What mastery looks like

  • Correctly define and calculate the mean, median, mode, and range of a small data set
  • Use 'outlier' correctly to identify a value that doesn't fit the pattern, and explain its effect on the mean
  • Use 'correlation' correctly when describing the relationship shown in a scatter graph

Check your understanding

If Statistical Analysis Vocabulary looked at a set of test scores from their class, could they find the mean, the median, and the range — and explain what each one tells you about how the class did?

Prerequisites

None — this is a foundational concept.
