Sr. # Questions Answers Choice
1 Formula to determine the size of a class is: X<sub>max</sub> - X<sub>min</sub> X<sub>max</sub> + X<sub>min</sub> Range/number of groups number of groups/Range
2 If variance is equal to 36 then the standard deviation will be: 36 6 -6 none of these&nbsp;
3 The measures that are  used to determine the degree or extent of variation in a data set are called: central value&nbsp; A.M measures of dispersion&nbsp; median
4 The harmonic mean of the observation 0,15,12, is: 3.7 7.3 6.7 no harmonic mean
5 The geometric mean of the a observations 2,4,8, is: 2 8 4 no geometric mean
6 The formula of group data of the median is: l + h/f (n/2 -c) l +∑fx/∑f x n, &nbsp;l + f<sub>m </sub>- f<sub>1</sub>/2f<sub>m</sub> - f<sub>1</sub> - f<sub>2</sub> x n, A + ∑fu/∑f x n
7 Coding formula of group data of the arithmetic mean is: X̅ = ∑fX/∑f X̅ = ∑fD/∑f X̅ = A + ∑fu/∑f x h X̅ = A + &nbsp;∑fu/∑f
8 The formula of grouped data of the arithmetic mean is:  X̅ = ∑X/n X̅ = A + ∑fX/∑X X̅ = ∑fX/n X̅ = l +n/f (n/2 - c)
9 Sum of the deviations of values x from its mean is always ''i.e ∑(x-x̅)’is to equal:  itself&nbsp; zero&nbsp; median&nbsp; mode&nbsp;
