The Maths Habit Handout to print

Two players threw five darts each. Who would you pick to be reliable? Why?

Player A
Player B

Player A: the darts land close together. Player B is all over the board. Close together is consistent.

Mode
The value there is most of.
Range
The biggest value take away the smallest value.
Consistent
Close together, with a small range.

  1. Ring the smallest and the biggest.No need to order every card.
  2. Range: biggest − smallest.A: 9 − 6 = 3. B: 10 − 3 = 7.
  3. The smaller range is more consistent.The numbers are closer together.
A is more consistent

Which group is more consistent? Ring the smallest and the biggest. Range: biggest − smallest. A 6, B 2: B
