This is a Massaschusetts Department of Elementary and Secondary Education (DESE) public data set on student retention. This report presents data on grade retention rates in Massachusetts public schools. The Massachusetts Department of Elementary and Secondary Education defines a student retention as: a student who was reported to have repeated the grade in which he or she was enrolled during the previous school year.
Combined all available years into one dataset. I calculated the dataset's quartiles and assigned each row to a quartile.
What are the most attending districts? Are there geopraphical patterns to absenteeism? Is there a correlations between retention and absenteeism?
Year (quantitative), District Name (Categorical), Chronically Absent (10% or more) (quantitative)
