Answer:
r =0.4437
Step-by-step explanation:
We have the follwoing dataset:
X: 20,23,53,4,24,32,35,24,31,23
Y: 30,35,40,38,37,45,50,34,42,32
n=10
The correlation coefficient is a "statistical measure that calculates the strength of the relationship between the relative movements of two variables". It's denoted by r and its always between -1 and 1.
And in order to calculate the correlation coefficient we can use this formula:
For our case we have this:
n=10
Th excel figure attached shows the calculations for each sum.
So then the correlation coefficient would be r =0.4437
