Question

Consider again the (x,y) values.

x	0	2	2	4	5
y	-1	0	4	6	7

Determine each of the following:

a) the sum of the x values

b) the sum of the y values

c) The sym of the xy values

d) The sum of the x-squared values

e) The sum of the y-squared values

f) The values of r, the correlation coeeficient

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.
