If you can’t explain it simply, you don’t understand it well enough.
— Albert Einstein, Physicist
Exploratory data analysis is providing that ability to simplify the data, reveals important insights, and often provides hidden patterns from a data set by analyzing and investigating the data.
It is the first and foremost step to analyze any kind of data and try to come up with a hypothesis about it which we can later test using hypothesis testing. Statisticians use it to take a bird’s eye view of the data and try to make some sense of it.
