(c) Determine and interpret the coefficient of
correlation.
The coefficient of correlation = _______.
It indicates a ( Answer
)moderate/strong/weak (Answer ) negative/ positive
(Answer ) curvilinear/ linear/ quadratic relationship of
the two variables.
(d) Determine and interpret the coefficient of
determination.
The coefficient of determination = _____
It implies that ________% of the variation in
the (Answer) number of visitors in Christmas/ Halloween/
