Let us represent the given values as x and their values are given are 3, 4, 6, 7, 9 and 10.
00:15
Let us represent the frequency values as f, and they are given as 2, 1, 9, 4, and 6.
00:27
Now adding all this gives the total frequency of 26.
00:33
Now the values of x into f is calculated as 6, 4, 54, 28, 36 and 60.
00:49
Now adding this gives the value of 188.
00:54
Now the mean is calculated as summation xi into fi divided by summation f f by summation f i from the table the values of summation x i into f5 is one eighty eight divided by the summation f i value is 26 now simplifying this gives the mean value of 7 .23.
01:25
Now, for each of the term, the value xi minus x bar, which is the mean value, the whole square, into the frequency f, are calculated as 35 .79, 10 .43, 13 .62, 0 .21, 12 .62, 0 .21, 12 .5 .1 .1 .12...
