17. Explorative Analysis = Find Insights =
Interesting Variables
Mean , Mode, Median, Standard Deviation + Factor Analysis + Variate
Analysis
EDA explores data to find relationships between measures that tells us they exist, without the cause.
They can be used to formulate hypotheses.
Write Travel Journal

Applied in physical or engineering sciences, situations that require
high precision and little room for error(only noise in data is
measurement error)
Designed to understand a biological or behavioral process, the
pathophysiology of a disease, or the mechanism of action of an
intervention.
