I'm david and i'm here to have you and change your question.
00:02
In the question here, we're going to discuss about the sample of correlation coefficient denoted by the r.
00:08
The formula will be the n times summation of the xy minus summation of the x times summation of the y, divided by the square root of the n times summation of the x, totally square, same thing for the y.
00:28
Now here we're given a dataset for the x and y, so let me bring it up here.
00:32
And from the dataset here, we need to find the volume the end, the summation of the x, the summation of the y, submission of the x square, submission of the y square, and the summation of the xy.
00:46
Now let me pass the data into the calculator.
00:50
I will have the minus 2 .5, 10 .3, minus 1 .7, 6 .1, 03, 3, 2 .3, 2 .3, 2.
01:03
4, 2, 6 minus 0 .5.
01:09
And then we get n equal to the 6 and the summation on the x equal to 8 .1.
01:17
Submission on the y equal to the 22 .9...
