{{short description|Approach of analyzing data sets in statistics}}

{{Data Visualization}}

In [[statistics]], '''exploratory data analysis''' (EDA) is an approach of [[data analysis|analyzing]] [[data set]]s to summarize their main characteristics, often using [[statistical graphics]] and other [[data visualization]] 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 and thereby contrasts traditional hypothesis testing. Exploratory data analysis has been promoted by [[John Tukey]] since 1970 to encourage statisticians to explore the data, and possibly formulate hypotheses that could lead to new data collection and experiments. EDA is different from [[Data analysis#Initial data analysis|initial data analysis (IDA)]],<ref>{{cite book |last=Chatfield |first=C. |year=1995 |title=Problem Solving: A Statistician's Guide |publisher=Chapman and Hall |isbn=978-0412606304 |edition=2nd }}</ref><ref>{{cite journal |doi=10.1371/journal.pcbi.1009819|title=Ten simple rules for initial data analysis|year=2022|last1=Baillie|first1=Mark|last2=Le Cessie|first2=Saskia|last3=Schmidt|first3=Carsten Oliver|last4=Lusa|first4=Lara|last5=Huebner|first5=Marianne|author6=Topic Group "Initial Data Analysis" of the STRATOS Initiative|journal=PLOS Computational Biology|volume=18|issue=2|pages=e1009819|pmid=35202399|pmc=8870512|bibcode=2022PLSCB..18E9819B |doi-access=free }}</ref> which focuses more narrowly on checking assumptions required for model fitting and hypothesis testing, and handling missing values and making transformations of variables as needed. EDA encompasses IDA.
