GOAL KICKING DATA: ACTIVITY 9
Class Activity / Discussion


Class Discussion: A Stem-and-Leaf Plot is a way to organise and represent data. In this activity we will be using a Stem-and-Leaf plot to present the average goals scored by AFL players.

For example:

Stevie-Lee Thompson
Ave. Goals: 0.4
Caitlin Gould
Ave. Goals: 0.5
Danielle Ponter
Ave. Goals: 0.7
Ashley Woodland
Ave. Goals: 1.8

The 'Stem' (the first digit or digits) and a 'Leaf' (usually the last digit).

STEM: LEAF:
0 7 8 9
1 3
Ashley Woodland

= Stem 1 and Leaf 8 is represented at 1.8

Class Discussion:

Plot these results as a class: The 'Stem' (the first digit or digits) and a 'Leaf'(usually the last digit) for this example.

Player 1 17
Player 2 15
Player 3 17

GOAL KICKING DATA: Activity 9 (Extension / Group Work Challenge)


When there are two sides or groups, we can use a two-sided Stem-and-Leaf plot.
Here is an example of a two-sided Stem-and-Leaf Plot.

Holding

Using your results from the first activity, create a Stem-and-Leaf plot comparing the ACL Men's (AFL) average goals to the AFC Women's (AFLW) average goals (Round to one decimal place).
