Algebra I Module 2, Topic A, Lesson 2

Class in Lecture Hall

Student Outcomes

  • Students construct a dot plot from a data set.
  • Students calculate the mean of a data set and the median of a data set.
  • Students observe and describe that measures of center (mean and median) are nearly the same for distributions that are nearly symmetrical.
  • Students observe and explain why the mean and median are different for distributions that are skewed.
  • Students select the mean as an appropriate description of center for a symmetrical distribution and the median as a better description of center for a distribution that is skewed.
