Exploratory data analysis - Wikipedia, the free encyclopedia

"Exploratory data analysis (EDA) is an approach to analysing data for the purpose of formulating hypotheses worth testing, complementing the tools of conventional statistics for testing hypotheses[1]. It was so named by John Tukey to contrast with Confirmatory Data Analysis, the term used for the set of ideas about hypothesis testing, p-values, confidence intervals etc. which formed the key tools in the arsenal of practising statisticians at the time."
