Abstract
Many K-12 teachers struggle to assess learning over time because of high rates of student turnover. In this study, we compare the independent and paired-samples t-test with and without missing value substitution. Results indicate that under certain conditions, the independent samples t-test offers more statistical power than the paired-samples t-test.
