Abstract:
This study looked at the effect of a number of factors such as the choice of analytical
method, the handling method for missing data, sample size, and proportion of missing
data, in order to evaluate the effect of missing data treatment on accuracy of estimation.
In order to accomplish this a methodological approach involving simulated data was
adopted. One outcome of the statistical analyses undertaken in this study is the
formulation of easy-to-implement guidelines for educational researchers that allows one
to choose one of the following factors when all others are given: sample size, proportion
of missing data in the sample, method of analysis, and missing data handling method.
