The width of each of five continuous classes in a frequency distribution is 5 and the lower class limit of the lowest class is 10. The upper limit of the highest class is
If the width of each of five continuous classes in a frequency distribution is 5 and the lower class limit of the lowest class is 10, then the upper limit of the highest class can be found as follows:
The upper limit of first class = 10+5=15
The upper limit of the fifth class=15 + 4 x 5 = 35.
