Question

The mean of a set of data is 4.68 and its standard deviation is 2.83. find the z score of the value

Answer 1

z=-0.35 ( Depending on value given)

Explanation:

Let the value be x. For calculation purposes, let us take x as 3.68. ( as mean is 4.68). We may assume a higher value as well. Depends on the given value.

The formula for z score is given as-

z=(value-mean)/Standard Deviation

z=(3.68-4.68)/2.83

z=-0.35
