Given
The above table
Required
The standard deviation
First, calculate the class mid-point. This is the average of the class interval.
The mid-point x is:
So, we have:
Calculate mean
The standard deviation is:
[] The fractions are
[] I see that 21 is a multiple of 7, so this one will be simple to solve.
-> 21 / 7 = 3, so we can do the following:
[] Now they have a common denominator of <u>21</u>
