I realised that a block of participants are all missing data on one question on my Friendship Questionnaire. Where this happened on the AQ I filled in the missing data with the mean scores, however this one is ranked data, i.e. the participants were asked to rank order three options. I’ve looked at filling in the score with the mean but it doesn’t make sense because of how the survey is scored (5 points if they rank a certain option first, 0 if they rank either of the other options first). Is there any way I can fill in this data?
Dear Hannah
Since it is related sample data, if you contact the respondents it would be better. Otherwise, and as the tests should be related statistical tests.Then, the incomplete surveys should be discarded /neglected, and the remaining (>30) surveys are sufficient for statistical analysis.

Dear Hannah,
Its not suggestive to fill missing value in case of rank data.
