Make Connections

Performance Task

Ways of Thinking: Make Connections

  • Take notes about any interesting discoveries that your classmates made about how adding or removing data points from a line plot affects the measures of center.

Hint:

As your classmates present, ask questions such as:

  • What was your goal when you explored the Line Plot with Stats interactive? How did you reach that goal?
  • What determines whether the mean will change and how it will change when you add data to a data set?
  • What determines whether the median will change and how it will change when you add data to a data set?
