5. The Decision Tree
Black & White Version available to download for your student folders.

6. Activity 1: Sorting the Decision Tree
Activity 1: Sorting the Decision Tree. The purpose of this activity is to help your students remember the layout and structure of the Decision Tree.

7. Activity 1: Sorting the Decision Tree

8. Activity 2: 3D Decision Activity 2: 3D Decision
The aim of this resource is to help students select and justify their choice of inferential statistical tests.

9. Activity 2: 3D Decision Activity 2: 3D Decision
Students need to select and justify the appropriate test for 6 scenarios, using the 3D method:
Difference? (Test of difference or correlation)
Design? (Independent groups or repeated measures/matched pairs)
Data? (Nominal, Ordinal, Internal)

10. Independent measures design Interval level data
Unrelated t-test
Test of difference
Independent measures design
Interval level data
Poll: Which statistical test would you select?
Pearson’s r
Unrelated t-test
Related t-test
Wilcoxon
Difference?
Design
Data?

11. Activity 3: Choosing the Right Test – Temple Run
The aim of this activity is to develop knowledge and understanding of inferential tests, by introducing an element of competition…

12. Activity 3: Choosing the Right Test – Temple Run
There are 8 different question cards and you’ll need one set of card per group.
Groups of 3 or 4 work perfectly for this activity. Each group is give Q1 face down…

13. Activity 3: Choosing the Right Test – Temple Run
In groups, they write their answer on the back of the card, plus a justification.
The ‘runner’ brings the card to the front and if correct they are given question 2…and the process repeats itself.
Mann-Whitney:
Test of difference
Independent groups design
Ordinal level data

14. 10 Application Handouts
We have also provided 10 Statistical Test Application Handouts that would make perfect starters, plenaries, homework activities, etc.
