How do I identify class width for a histogram with four classes in which the lowest value-10.4 highest-97.7
I tried subtracting the highest from the lowest and dividing by four and started the limits from 1 but then that doesnt include the 90.
And then the class widths should be equal.

Don't start from 1. Start from 10.4 since that is the lowest value you have. You started corredtly by subtracting and dividing by 4. This gives you the length of each class and by my calculations it is 21.825. Therefore you add this to 10.4 and continue this way until you get to 97.7:

10.4 to 32.225
32.225 to 54.05
54.05 to 75.875
75.875 to 97.7
 
Wow. Nothing can say how silly I feel right now. Was it really that simple? Lol! Thank you.
