Analysing the IPSOS MORI data
- To analyse, we undertook the chi squared test of significance
- Measure the relationship between age and satisfaction with life

- You will not be asked to explain chi-squared. It is a statistical test like Spearman's rank (which you DO need to know!)
Null hypothesis
- In statistics, you assume there is no relation until one is proven.
- No relation = null hypothesis
- We proved (using chi squared) that there WAS a relation, hence we reject the null hypothesis,
