Standard deviation for frequency distribution:
The formula for standard deviation
Where x - mid point of the class interval
f - frequency of each class interval
The formula to find the mid point is,
For first class 0 - 3, the midpoint is
Similarly the midpoints of the classes are 5.5, 9.5, 13.5, 17.5 and 21.5 respectively.
Number of customers are nothing but the frequencies.
The formula of mean is
The standard deviation is,
Standard deviation = 5.4
