What is the difference between exploratory and confirmatory data analytics projects?
-Exploratory projects involve testing hypotheses and finding patterns in data, while
confirmatory projects involve verifying existing hypotheses.
, -Exploratory projects involve analyzing data from a single source, while confirmatory
projects involve integrating data from multiple sources.
-Exploratory projects involve analyzing data that is already structured, while
confirmatory projects involve analyzing unstructured data.
-Exploratory projects involve analyzing large datasets, while confirmatory projects
involve analyzing smaller datasets. - ANSWER-Exploratory projects involve testing
hypotheses and finding patterns in data, while confirmatory projects involve verifying
existing hypotheses. (Exploratory data analytics projects are typically used when
little is known about the data or when researchers look for patterns or trends that
may not have been previously identified.)
