Comparing measurements
Describe, interpret, and compare distributions of a single variable using appropriate measures of central tendency (mean, median, mode) and spread (range), including the effect of outliers
Teaching approaches
Gakuva’s recommended starting approach is selected. You can still compare every option.
1 approach
If your child had the test scores of a whole class, could they find the mean, median, and range, and explain what each tells you about how the class performed?
