Overall Summary

Figure 1. Overall summary of missing values
Overall summary of missing values

The overall summary of missing values displays three pie charts that show different aspects of missing values in the data.

  • The Variables chart shows that each of the 10 analysis variables has at least one missing value on a case.
  • The Cases chart shows that 525 of the 1000 cases has at least one missing value on a variable.
  • The Values chart shows that 792 of the 10,000 values (cases × variables) are missing.

Each case with missing values has, on average, missing values on roughly 1.5 of the 10 variables. This suggests that listwise deletionwould lose much of the information in the dataset.
