Exploratory Data Analysis (EDA) Definition/Meaning:
A term invented by J. W. Tukey to denote
techniques for looking at numerical data with a view to discerning pattern.
Exploratory data analysis is open-ended and makes few prior assumptions about
the nature of any pattern that may be found. Graphical techniques are freely
used. It can be contrasted with model-fitting techniques, which make highly
specific prior assumptions. Statistical methods contain aspects of both these
processes.
