Abstract
Previous research has shown that the independent samples t-test outperforms the paired-samples t-test with listwise deletion in pre-test/post-test situations if there is a high proportion of missing data. The present study builds on that research by demonstrating that the advantage holds when the missing data are missing not at random.
