Question

HOW WELL CORRELATED ARE THESE VARIABLE? WE MUST CALCULATE THE CORRELATION COEFFICIENT (r) USING THE SAME (X,Y) DATA POINTS

	X	X^2	Y	Y^2	X*Y
	4		6
	3		7
	5		12
	11		17
	10		10
	14		14
SUMS = ∑	47		66

nƩ (X*Y)=

(ƩX) * (ƩY) =

'nƩX^2 =

(ƩX)^2 =

n ƩY^2 =

(ƩY)^2 =

'CORRELATION COEFFICIENT (r) =

Answer 1

TOPIC:Correlation coefficient.

INTERPRETATION:

There is a moderately high and positive relationship between X and Y.(ANSWER)
