We know scattered diagram means that it is the simplest way of the diagram metric representation of via variate data and thus for for via variate data and thus for via y rate distribution x i comma y i that is i is equal to one to two to n if the value of variables x and y are plotted along x x x x and y respectively in x y plane the diagram of dots so obtained is known as scatter diagram now in our problem let x is the placement test and y is the course crate that that is it is 50, 35, 55, 35, 90, 60, 60, 55, 55, 65, and other 53, 61, 168, 11, 79, 54, 48, 71, 53, and 57.

Now, scattered diagram is, this is the scattered diagram and here we can say x, y, x, square, y square, xy, in tabler form.
03:05
Where values is 20, 23, 8, 29, 14, 12, 11, 11, 27.
03:19
And 18.
03:22
Then finally its total.
03:28
This is the table calculations and the total value is of the summation x is 172.
03:38
Summation of y is 200 then summation of x squared is 3308, summation of y square is 4 to 5 to, summation of xy is 3667.
03:58
Now, x, war, that is, summation of x over n, that is 172 over 10, which is 17 .2.
04:10
Then y -war, summation of y over n, that is 200 over 10, that is 20...
