About this worksheet

What students practice

Students calculate mean, median, interquartile range, and mean absolute deviation from care records.
Students describe distribution patterns and interpret a striking outlier in context.
Students use statistical summaries to evaluate feeding and tank-care plans.

How to use

Have students show calculations on separate paper. Review how quartiles and absolute distances are found, then discuss what the summaries can and cannot tell aquarium staff.
