Statistics: Practical Concept of Statistics for Data Scientists
By John Slavio
()
About this ebook
Statistics are not a tool but rather a set of techniques that you have access to that will help you analyze a set of data that you either generate, receive, or give. Statistics are absolutely vital for those attempting to study Big Data because it allows the scientists studying the data to make sense of the information when the information is on such a large and global scale. Unlike local neighborhood statistics or marketing statistics, big data encompasses a huge range of information and often this big data will be populated by thousands if not millions of data points. Statistics help you break down these data points so that you can reasonably understand them and work with the data that comes into you.

Exploratory Data Analysis
What is EDA?
Exploratory data analysis is not a tool but rather a set of techniques that, if possessed, will help one analyze a set of data that had been previously generated, received, or given. Exploratory data analysis is absolutely vital for people attempting to study big data because it allows them to make sense of information on a large or global scale. Unlike local neighborhood statistics or marketing statistics, big data encompasses a huge range of information and is often populated by thousands if not millions of data points. Exploratory data analysis helps to break down these data points so that they can be reasonably understood and put into good use.
What Can EDA do?
Insights into a Data Set
Exploratory data analysis helps in two different ways. By presenting a graphical view of the data set being analyzed and the quantitative view that the data can be seen from. With the graphical view of the dataset, one can begin to see trends in data without a need to run algorithms to see if such a pattern exists. By using Scatter Plots or bar graphs, one can also easily gauge where certain commonalities are occurring for better predictions and understanding of the data being studied. With the quantitative view, one is able to take those graphical views and explore them in depth while also determining the reasoning behind the patterns that can be seen in the dataset. Additionally, the quantitative view of the dataset may be used to test hypotheses and provide an estimated guess as to what future data will look like during certain intervals.
See Underlying Structure
Thanks to the fact that the information can be viewed in a more graphical form, you can begin to understand the underlying structure that comprises the variables present in such information. When viewing the raw data format, all one sees is a large mass of numbers that doesn't really provide a cohesive relationship of everything that is going on inside of those numbers but whenever the graphical form of the numbers is adapted, an understanding of how these numbers come into existence is realized. One can then take it even further by using quantitative formulas to break down the data points and test hypotheses so as to see the true underlying structure that make up the data points, how those data points got to that location and how those data points
