Sum these deviations

Find the median of these deviations

None of the above

Multiply these deviations

The values are closely packed around the mean

The mean of the dataset is zero

The dataset contains no outliers

The values are widely spread from the mean

Scores are more consistent

Scores vary more from the mean

The test was easier

All students scored the same

Reveals the spread of scores around the mean

Indicates the average score

Shows the highest score

Determines the passing rate

Class 1 had more consistent scores

Class 1 had lower scores
