Do you find quizzes irresistible? I do.

Here’s a little quiz about working with missing data:

**True or False?**

1. Imputation is really just making up data to artificially inflate results. It’s better to just drop cases with missing data than to impute.

2. I can just impute the mean for any missing data. It won’t affect results, and improves power.

3. Multiple Imputation is fine for the predictor variables in a statistical model, but not for the response variable.

4. Multiple Imputation is always the best way to deal with missing data.

5. When imputing, it’s important that the imputations be plausible data points.

6. Missing data isn’t really a problem if I’m just doing simple statistics, like chi-squares and t-tests.

7. The worst thing that missing data does is lower sample size and reduce power.
