The S.D. of 7 scored `1, 2, 3, 4, 5, 6,7` is

The S.D of 7 scores 1, 2, 3, 4, 5, 6, 7, is

The S.D. of 5 scores 1, 2, 3, 4, 5 is :

The standard deviation of 7 scores 1,2,3,4,5,6,7 is

The standard deviation of 7 scores 1,2,3,4,5,6,7 is

Statement-1 : The S.D. of 5 scores 1 2 3 4 5 is sqrt2 . Statement-2 : S.D. = sqrt"variance"

Find the mode of the scores 4, 5, 3, 2, 5,3,6,5,7,1

The standard deviation for the scores 1,2,3,4 ,5,6,and 7 is 2. Then , the standard deviation of 12,23,34,45,56,67and78 is a)2 b)4 c)22 d)11

For the binary operation xx_7 on the set S={1,\ 2,\ 3,\ 4,\ 5,\ 6} , compute 3^(-1)xx_7 4 .
