WebListwise and pairwise deletion are the most common techniques to handling missing data (Peugh & Enders, 2004). It is important to understand that in the vast majority of cases, an important assumption to using either of these techniques is that your data is missing completely at random (MCAR). In other words, the researcher needs to support ...
