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 $\sum xy=\;$
$\displaystyle SSX = \;$
$\displaystyle SSY = \;$
$\displaystyle SPXY = \;$
Hence calculate the correlation coefficient $r$:
$r=\;$
