Basic EDA for Multilevel Data in R
Multilevel data is data that includes repeated measures of the same subject or variables over some period of time e.g:
A five-year study on the test scores of students grouped by cohorts and classes across a state’s K-12 schools
Patient satisfaction of care grouped by attending doctors and their respective practices
Police use of force incidents by race of suspect grouped by precinct, patrol, and arresting officer
Analysts can encounter data of this type in just about any conceivable industry that produces data and the grouping structure must be fully understood to properly explore, model, and simulate before creating any usable insight.
