q2 · i? · associational · r?
The report's analysis of district turnover rates finds an association between turnover and student poverty; it also notes roughly 1 in 10 districts has turnover rates of 25% or more while nearly 1 in 10 has rates under 5%.
"Districts with higher turnover rates also have greater proportions of students from low-income families compared to those with the lowest turnover rates."
