Part20 Introduction to Exploratory Data Analysis & Descriptive Statistics."

Objectives: To learn how to analyze data sets, applying methods of descriptive statistics and visualization in R.

“In statistics, Exploratory Data Analysis (EDA) is an approach to analyzing data sets to summarize their main characteristics, often with visual methods. A statistical model can be used or not, but primarily EDA is for seeing what the data can tell us beyond the formal modeling or hypothesis testing task.”" (Wikipedia)

“Descriptive statistics aims to summarize a sample, rather than use the data to learn about the population that the sample of data is thought to represent. This generally means that descriptive statistics, unlike inferential statistics, are not developed on the basis of probability theory.”" (Wikipedia)
