Gap-fill
Ask the student a question, and give any hints about how they should answer this part.
| Wife $(X)$ | $\sum x=\;$ |
$\sum x^2=\;$ |
|---|---|---|
| Husband $(Y)$ | $\sum y=\;$ |
$\sum y^2=\;$ |
Also find $\sum xy=\;$
Hence calculate the correlation coefficient $r$ correct to 3 decimal places:
$r=\;$
Use this tab to check that this question works as expected.
