Data Analyst Job Description | What 4 Skills Will You Need To Be A Data Analyst?
In this video we are going to define the job description of a data analyst, what a data analyst does, and the best online course to become a data analyst. ► Full Playlist Explaining Data Jargon ( http://bit.ly/2mB4G0N ) ► Top 4 Best Laptops for Data Analysts ( https://youtu.be/Vtk50Um_yxA ) ► Break Into the Data Industry with the best data analytics online learning resources from Edureka! ( http://bit.ly/2yCbsac ) --- affiliate link to help support this channel!^ Currently the average pay for a data analyst is $76,419 on the button, according to glassdoor I receive a lot of questions about what it takes to become a data analyst and what is a data analyst. Clearing up what a data analyst does everyday and what that description means to someone looking to enter the data science industry What will you actually be asked to do on the day to day as a data analyst. ► Top 4 Responsibilities in the Daily Life of a Data Analyst: 1 ) Mathematics Although mathematics only makes up about 20% of the day to day life of a data analyst. It is still important to have a strong understanding of the foundations of mathematics. - Addition - Subtraction - Multiplication - Division - Most Importantly --- Statistics Data analytics is all about statistics. Most of the statistics will be handled by the tools you are working with, but in order to be a great data analyst it is best to know why the tools are producing specific results. A strong understanding of statistics will be useful to you. 2 ) Computer Programming You must be able to work proficiently in one or more computer programming languages. This make up for roughly 60%-70% of your daily work. in order to analyze data it must be queried (drawn) from a large data warehouse. You will use computer programming languages such as SQL, Python, and R to query data. Before we move on let me define the term Query, if it does not resonate with you. You need strong computer programming skills in order to accomplish this task. As a data analyst you will do a lot of drawing and analyzing data. ► For more info on databases, SQL, and other jargon check out our Video Series on Data Jargon ( https://www.youtube.com/playlist?list=PL_9qmWdi19yDhnzqVCAhA4ALqDoqjeUOr ) 3 ) Know the Tools of the Trade Once you query data from the database onto your workspace you will begin to utilize data analytics tools to process, scrub, and analyze data (data Jargon explained on our Video series ^^^). You will be able to perform these tasks by using tools like Hadoop, Open Refine, Tableau, Apache Spark, etc... As you process the data you will begin to see connections between the data sets. You will see some of the following errors and you will want to remove these in order to ensure that your data analysis is accurate: - Duplicated data - Improperly formatted data - Incomplete data - Inaccurate data - This data will corrupt your findings and could possibly lose you client or employer millions of dollars. Make sure you know how to use those data analytics tools WELL! 4 ) Communicate and Present Insights Data Analyst will also be called upon to clearly and consciously present your research to clients, managers, or executives. Ok, now I know you are curious if you are capable of learning all of these crucial skills. Yes, you can, but there is a clause. You have to learn from the best. The guys over at Edureka.co are the leading professionals in the big data training industry. Based out of India, home to over 101,000 individuals in the data science industry (at the time of this writing). They are eager to make a way for themselves in the new digital economy. They are on the cutting edge of data analytics and eager to teach it to anyone worldwide. Testimonies of increased salaries, new employment, and 597,089 (updated) satisfied learners make edureka the best choice to learn the skills you need in the data industry. Question is will you actually do it. Imagine deregulating yourself for the data industry. Right now, it is a black hole, you don't know what's inside, but it is screaming opportunity from the darkness. TURN ON THE LIGHT and break into the data industry.

What is GROUNDED THEORY? What does GROUNDED THEORY mean? GROUNDED THEORY meaning & explanation
I MAKE CUTE BABIES - https://amzn.to/2DqiynS What is GROUNDED THEORY? What does GROUNDED THEORY mean? GROUNDED THEORY meaning - GROUNDED THEORY definition - GROUNDED THEORY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. Grounded theory (GT) is a systematic methodology in the social sciences involving the construction of theory through the analysis of data. Grounded theory is a research methodology which operates almost in a reverse fashion from social science research in the positivist tradition. Unlike positivist research, a study using grounded theory is likely to begin with a question, or even just with the collection of qualitative data. As researchers review the data collected, repeated ideas, concepts or elements become apparent, and are tagged with codes, which have been extracted from the data. As more data are collected, and as data are re-reviewed, codes can be grouped into concepts, and then into categories. These categories may become the basis for new theory. Thus, grounded theory is quite different from the traditional model of research, where the researcher chooses an existing theoretical framework, and only then collects data to show how the theory does or does not apply to the phenomenon under study. Grounded theory combines diverse traditions in sociology, positivism and symbolic interactionism as it is according to Ralph, Birks & Chapman (2015) "methodologically dynamic". Glaser's strong training in positivism enabled him to code the qualitative responses, however Strauss's training looked at the "active" role of people who live in it. Strauss recognized the profundity and richness of qualitative research regarding social processes and the complexity of social life, Glaser recognized the systematic analysis inherent in quantitative research through line by line examination, followed by the generation of codes, categories, and properties. According to Glaser (1992), the strategy of Grounded Theory is to take the interpretation of meaning in social interaction on board and study "the interrelationship between meaning in the perception of the subjects and their action". Therefore, through the meaning of symbols, human beings interpret their world and the actors who interact with them, while Grounded Theory translates and discovers new understandings of human beings' behaviors that are generated from the meaning of symbols. Symbolic interactionism is considered to be one of the most important theories to have influenced grounded theory, according to it understanding the world by interpreting human interaction, which occurs through the use of symbols, such as language. According to Milliken and Schreiber in Aldiabat and Navenec, the grounded theorist's task is to gain knowledge about the socially-shared meaning that forms the behaviors and the reality of the participants being studied. Once the data are collected, grounded theory analysis involves the following basic steps: 1. Coding text and theorizing: In grounded theory research, the search for the theory starts with the very first line of the very first interview that one codes. It involves taking a small chunk of the text where line by line is being coded. Useful concepts are being identified where key phrases are being marked. The concepts are named. Another chunk of text is then taken and the above-mentioned steps are being repeated. According to Strauss and Corbin, this process is called open coding and Charmaz called it initial coding. Basically, this process is breaking data into conceptual components. The next step involves a lot more theorizing, as in when coding is being done examples are being pulled out, examples of concepts together and think about how each concept can be related to a larger more inclusive concept. This involves the constant comparative method and it goes on throughout the grounding theory process, right up through the development of complete theories. 2. Memoing and theorizing: Memoing is when the running notes of each of the concepts that are being identified are kept. It is the intermediate step between the coding and the first draft of the completed analysis. Memos are field notes about the concepts in which one lays out their observations and insights. Memoing starts with the first concept that has been identified and continues right through the process of breaking the text and of building theories. 3. Integrating, refining and writing up theories: Once coding categories emerges, the next step is to link them together in theoretical models around a central category that hold everything together.

Statistical Text Analysis for Social Science
What can text analysis tell us about society? Corpora of news, books, and social media encode human beliefs and culture. But it is impossible for a researcher to read all of today's rapidly growing text archives. My research develops statistical text analysis methods that measure social phenomena from textual content, especially in news and social media data. For example: How do changes to public opinion appear in microblogs? What topics get censored in the Chinese Internet? What character archetypes recur in movie plots? How do geography and ethnicity affect the diffusion of new language? In order to answer these questions effectively, we must apply and develop scientific methods in statistics, computation, and linguistics. In this talk I will illustrate these methods in a project that analyzes events in international politics. Political scientists are interested in studying international relations through *event data*: time series records of who did what to whom, as described in news articles. To address this event extraction problem, we develop an unsupervised Bayesian model of semantic event classes, which learns the verbs and textual descriptions that correspond to types of diplomatic and military interactions between countries. The model uses dynamic logistic normal priors to drive the learning of semantic classes; but unlike a topic model, it leverages deeper linguistic analysis of syntactic argument structure. Using a corpus of several million news articles over 15 years, we quantitatively evaluate how well its event types match ones defined by experts in previous work, and how well its inferences about countries correspond to real-world conflict. The method also supports exploratory analysis; for example, of the recent history of Israeli-Palestinian relations.

YOW! Lambda Jam 2016 Tim Thornton - Data Analysis with Vector Functional Programming #YOWLambdaJam
Vector / array functional programming languages have been around for a long time, beginning with the introduction of APL. Modern dialects of APL such as j, k, and q offer a radical paradigm of functional programming wherein arrays are at the forefront of computation, and through the use of specific higher-order functions known as ‘adverbs’, programmers can concisely express complex algorithms and programs without resorting to loops, and rarely resorting to explicit recursion. This talk will provide an introduction to the paradigm of vector functional programming through the use of the q programming language, a very efficient, interpreted, dynamically-typed vector language from Kx Systems. After giving a brief history of vector languages, select syntax and semantics of the language will be introduced, emphasizing the terse notation as a facilitator of thought, as expressed in Iverson’s Turing Award paper 1. Through small examples of vector and atomic operations, to run-length encoding, key ideas such as verbs and adverbs, atomic vector operations, and array-based functional programming adhering to the “rule” of “no stinking loops” 2 will be demonstrated. After an introduction to the language, an end-to-end example will be shown within a practical domain for vector functional programming: fast data analysis. The analysis will involve reading data from CSV files, scraping and processing data from the web, joining gathered data, and analysis — all using Q. The attendee will leave the talk with a basic understanding of the vector functional paradigm, how it may be useful in practical domains, an understanding of array-based thinking (practical in any functional programming language), and hopefully, an appreciation — or at least openness — toward terse and precise syntax. 1 http://www.jsoftware.com/papers/tot.htm 2 http://nsl.com Tim Thornton is a q and web developer and functional programming enthusiast. Working at FD Labs (formerly Bedarra Research Labs), Tim spends his days applying vector programming to various data analysis challenges, primarily within data visualization. His interest in type theory motivated his undergraduate thesis designing a static refinement type system for q. For more on YOW! Lambda Jam, visit http://lambdajam.yowconference.com.au

Overview of �Big Data� Research at TU Berlin
Intro - By Volker Markl Part 1 - Query Optimization with MapReduce Functions, Kostas Tzoumas Abstract: Many systems for big data analytics employ a data flow programming abstraction to define parallel data processing tasks. In this setting, custom operations expressed as user-defined functions are very common. We address the problem of performing data flow optimization at this level of abstraction, where the semantics of operators are not known. Traditionally, query optimization is applied to queries with known algebraic semantics. In this work, we find that a handful of properties, rather than a full algebraic specification, suffice to establish reordering conditions for data processing operators. We show that these properties can be accurately estimated for black box operators using a shallow static code analysis pass based on reverse data and control flow analysis over the general-purpose code of their user-defined functions. We design and implement an optimizer for parallel data flows that does not assume knowledge of semantics or algebraic properties of operators. Our evaluation confirms that the optimizer can apply common rewritings such as selection reordering, bushy join order enumeration, and limited forms of aggregation push-down, hence yielding similar rewriting power as modern relational DBMS optimizers. Moreover, it can optimize the operator order of non-relational data flows, a unique feature among today's systems. Part 2 - Spinning Fast Iterative Data Flows, Stephan Ewen Abstract: Parallel data flow systems are a central part of most analytic pipelines for big data. The iterative nature of many analysis and machine learning algorithms, however, is still a challenge for current systems. While certain types of bulk iterative algorithms are supported by novel data flow frameworks, these systems cannot exploit computational dependencies present in many algorithms, such as graph algorithms. As a result, these algorithms are inefficiently executed and have led to specialized systems based on other paradigms, such as message passing or shared memory. We propose a method to integrate "incremental iterations", a form of workset iterations, with parallel data flows. After showing how to integrate bulk iterations into a dataflow system and its optimizer, we present an extension to the programming model for incremental iterations. The extension alleviates for the lack of mutable state in dataflows and allows for exploiting the "sparse computational dependencies" inherent in many iterative algorithms. The evaluation of a prototypical implementation shows that those aspects lead to up to two orders of magnitude speedup in algorithm runtime, when exploited. In our experiments, the improved dataflow system is highly competitive with specialized systems while maintaining a transparent and unified data flow abstraction. Part 3 - A Taxonomy of Platforms for Analytics on Big Data, Thomas Bodner Abstract: Within the past few years, industrial and academic organizations designed a wealth of systems for data-intensive analytics including MapReduce, SCOPE/Dryad, ASTERIX, Stratosphere, Spark, and many others. These systems are being applied to new applications from diverse domains other than (traditional) relational OLAP, making it difficult to understand the tradeoffs between them and the workloads for which they were built. We present a taxonomy of existing system stacks based on their architectural components and the design choices made related to data processing and programmability to sort this space. We further demonstrate a web repository for sharing Big Data analytics platform information and use cases. The repository enables researchers and practitioners to store and retrieve data and queries for their use case, and to easily reproduce experiments from others on different platforms, simplifying comparisons.

Data analysis to improve service quality and customer satisfaction:suzuki's Group
The Suzuki Laboratory is pursuing a broad range of research based on data analysis. This includes the development of statistical methodologies and applied research on quality control and marketing, as well as statistical quality control. The Suzuki Lab also does investigative research on customer relationship management, consumer behavior analysis, and sports management. Q.One of our projects is to improve customer satisfaction with pro baseball through field surveys. Our students actually do this work at ballparks, by such means as collecting opinions from spectators and conducting questionnaire surveys. By collecting and analyzing this data, we evaluate the quality of services and investigate how satisfied customers are. The first stage of data analysis is simply collecting statistics. Students design questions, then hand out questionnaires at ballparks. The students first of all propose their own hypotheses, so they can design questionnaires to see what sort of things customers want, or what sort of things should be evaluated. The data brought back to the Suzuki Lab then enters the analysis stage. The analysis method used is covariance structure analysis, an advanced form of multivariate analysis. Covariance structure analysis shows how each factor affects the results, and how the factors influence each other. For example, if a team has better fan services, customers are more inclined to support the team, watch it play, and be satisfied overall. Also, the figures show that fan services have a big impact on overall satisfaction, and that they function effectively. Results like these are displayed in graphical forms that can be understood at a glance. This makes it possible to verify, from various perspectives, what constitutes improvements in service quality and customer satisfaction, and what must be done to achieve them. The Suzuki Lab also has partnerships with a variety of businesses, and is steadily getting results through hands-on surveys and analysis. Q.We firmly believe that these results are helpful. In fact, weve actually demonstrated this already. Looking ahead, wed like to continue forming industrial-academic partnerships with businesses, so we can not only make academic contributions, but do research that is relevant to business and has a social impact as well. Data analysis methodologies evolve day by day. The Suzuki Lab makes progress by considering the social environment in which businesses operate.

Stanford Seminar - Towards theories of single-trial high dimensional neural data analysis
EE380: Computer Systems Colloquium Seminar Towards theories of single-trial high dimensional neural data analysis Speaker: Surya Ganguli, Stanford, Applied Physics Neuroscience has entered a golden age in which experimental technologies now allow us to record thousands of neurons, over many trials during complex behaviors, yielding large-scale, high dimensional datasets. However, while we can record thousands of neurons, mammalian circuits controlling complex behaviors can contain tens of millions of behaviorally relevant neurons. Thus, despite significant experimental advances, neuroscience remains in a vastly undersampled measurement regime. Nevertheless, a wide array of statistical procedures for dimensionality reduction of multineuronal recordings uncover remarkably insightful, low dimensional neural state space dynamics whose geometry reveals how behavior and cognition emerge from neural circuits. What theoretical principles explain this remarkable success; in essence, how is it that we can understand anything about the brain while recording an infinitesimal fraction of its degrees of freedom? We present a theory that addresses this question, and test it using neural data recorded from reaching monkeys. Overall, this theory yields a picture of the neural measurement process as a random projection of neural dynamics, conceptual insights into how we can reliably recover neural state space dynamics in such under-sampled measurement regimes, and quantitative guidelines for the design of future experiments. Moreover, it reveals the existence of phase transition boundaries in our ability to successfully decode cognition and behavior on single trials as a function of the number of recorded neurons, the complexity of the task, and the smoothness of neural dynamics. We will also discuss non-negative tensor analysis methods to perform multi-timescale dimensionality reduction and demixing of neural dynamics that reveal how rapid neural dynamics within single trials mediate perception, cognition and action, and how slow changes in these dynamics mediate learning. About the Speaker: Prof. Surya Ganguli triple majored in physics, mathematics, and electrical engineering and computer science at MIT, completed a masters in mathematics and a PhD in string theory at Berkeley, and a postdoc in theoretical neuroscience at UCSF. He is now a professor of Applied Physics at Stanford where he leads the Neural Dynamics and Computation Lab, and is also a consulting professor at the Google Brain Research Team. His research spans the fields of physics, machine learning and neuroscience, focusing on understanding and improving how both biological and artificial neural networks learn striking emergent computations. He has been awarded a Swartz-Fellowship in computational neuroscience, a Burroughs-Wellcome Career Award at the Scientific Interface, a Terman Award, NIPS Outstanding Paper Award, an Alfred P. Sloan foundation fellowship, a James S. McDonnell Foundation scholar award in human cognition, a McKnight Scholar award in Neuroscience, and a Simons Investigator Award in the mathematical modeling of living systems.

OpenfMRI allows neuroscientists to share brain research data - Science Nation
Researchers around the world can compare notes on one of the most powerful tools available for imaging human brain function, the fMRI, thanks to support from the National Science Foundation (NSF). An fMRI is a functional magnetic resonance imaging scan that measures brain activity by detecting changes in blood oxygenation and flow. Researchers use fMRI to watch how blood flows through active areas of the brain in real time, and the scans can be used to produce "maps" of activity during a brain's thought processes. These maps change based on what a person is thinking. Globally, researchers run more than 2,000 fMRI studies every year, but currently, there is limited infrastructure for sharing results. With support from NSF's Directorate for Computer and Information Science and Engineering (CISE), cognitive neuroscientist Russell Poldrack and a team at Stanford University launched new infrastructure to enable sharing. The project, called OpenfMRI, allows scientists to share their data easily and securely in a standardized format. The advantages are clear to Stanford neuroscientist Vinod Menon, who researches brain development in children with ADHD and autism. Menon is using OpenfMRI to validate his research because he says the more fMRI scans he can analyze, the more certain he can be of his conclusions. Menon says as more studies are added to OpenfMRI, it becomes a powerful tool for diagnosing and treating neurological disorders. The research in this episode is supported by NSF grant #1131441 , CRCNS Data Sharing: An open data repository for cognitive neuroscience: The OpenfMRI Project. CRCNS stands for Collaborative Research in Computational Neuroscience.
