In a short essay, list and discuss the three options available to the researcher for the treatment of missing responses on a questionnaire
What will be an ideal response?
a. Substitute a neutral value - a neutral value, typically the mean response to the variable, is substituted for missing responses. Thus, the mean of the variable remains unchanged and other statistics, such as correlation, may not be affected much if the proportion of missing values is small.
b. Casewise deletion - in casewise deletion, cases or respondents with any missing responses are discarded from the analysis. However, casewise deletion could lead to a significant reduction in the sample size and should be used with caution.
c. Pairwise deletion - in pairwise deletion, instead of discarding all cases with any missing values, the researcher uses only the cases or respondents with complete responses for each calculation. However, pairwise deletion could also lead to a reduction in the sample size.
