Question

Below is a set of data from a sample of n = 11:

X 3 6 10 12 4 9 15 18 7 5 8
Y 9 18 30 36 12 27 45 54 21 15 24

Answer the following questions:
(a) Calculate the covariance.
(b) Calculate the coefficient of correlation.
(c) What conclusions can you reach about the relationship between X and Y? Explain.

Definition Definition Relationship between two independent variables. A correlation tells the degree to which variables move in relation to each other. When two sets of data are related to each other, there is a correlation between them.
