Exploratory Data Analysis

Powell & Associates Science Services has extensive experience in using exploratory and inferential data analysis (EDA) to analyze complex problems and find the causes of and solutions for those problems. Links to an EDA introduction and two detailed examples of the use of EDA are provided below.

J.W. Tukey coined the term “exploratory data analysis,” in 1977. He defined and described EDA as follows:

“…the examination of data with minimal preconceptions about its structure through which it is hoped that relationships and patterns, at least some of which are unanticipated, will be uncovered.”
