This document outlines an activity where students will use Gapminder to investigate relationships between two statistical variables over time. Students will find a noticeable relationship, discuss possible reasons for it, and conduct research to justify their proposed reasons. They will then create a Smart Notebook presentation with slides showing the relationship, their proposed reasons, and the results of their research. Finally, each group will report their findings and the relationship they determined was most noticeable and easily explained to the class.

1. Mathematics Stage 5 – Year 10 –
Statistics and Probability – Bivariate
Data Analysis
Outcomes:
- Selects appropriate notations and conventions to communicate mathematical
ideas and solutions. MA5.2-1WM
- Constructs arguments to prove and justify results. MA5.2-3WM
- Investigates relationships between two statistical variables, including their
relationship over time. MA5.2-16SP
Group 2: Joshua Woodland, Mark Hamilton, Geoffrey Lee, Matt Lovegrove & Wesley Lummis

2. Gapminder
• Students will use Gapminder, and look at real life
statistic variables until they find a noticeable
relationship between two variables. Eg. Income per
person and life expectancy.

3. Discussion
• Once students have found a relationship between
two statistic variables, they will get into groups of 4,
where they will have time to come up with ideas for
why the relationships they noticed may occur.
Students should then use the internet to investigate
possible reasons for their relationship.

4. Smart Notebook
• Once research has been completed, students should
use smart notebook to create three slides per
relationship, the first should contain a screen capture
of the relationship they have been researching, the
second the possible reasons the group thought might
be the reason for this and the third an argument
constructed to justify possible reasons this
relationship may have occurred. Students will use
self regulation to ensure they will have finished their
slides at the same time as the other members of
their group.

5. Discussion
• Once students have created their three slides they
must discuss their findings with the other members of
their group until it is agreed which relationship was the
most noticeable and easily explained. They should then
add in any additional information or ideas they have
found onto those slides.

6. Report
• Finally each group should report their findings on
this relationship to the class, ensuring they use their
smart notebook slides to show the relationship they
chose, what they thought might be the reason this
relationship occurred and finally what their research
showed the relationship may be caused by.
