Finding the mean, median, mode and range of a list, and reversing a stated mean.

Author note — to cover

  • Working backwards — a missing value from a stated mean, and the mean of two combined groups through their totals (4 questions).
  • Order and outliers — single-choice questions catching the median of an unordered list, and naming which average an outlier drags (4 questions).
