Vocabulary
Mean: The average of a set of numbers.
Median: The middle number in an ordered set.

Common Mistakes
  • Forgetting to order numbers for Median
  • Confusing Mean and Median
  • Not ordering numbers for median
  • Confusing mean/median/mode
  • Incorrect range calculation
  • Arithmetic errors during mean
Differentiation
SupportFocus on Mode and Range first.
ChallengeFind the mean of a set with a decimal answer.
Discussion Questions
  • Which average (mean, median, mode) is best for describing the data?
  • When is the mean most useful?
  • Why is ordering important for median?
  • Can a data set have no mode?
  • How does an outlier affect range?
Extension Activities
  • Collect class data (shoe size) and find the stats.
