Compute the product moment correlation coefficient briefly comment on the value acquired
The produce moment correlation:
Workings:
x¯ = 4020/10 = 402
y¯ = 3550/10 = 355
= 0.89
Comment: The value acquired 0.89 suggests that the correlation between annual expenditure and annual income is high and positive. This shows that the more one earns the more one spends.
