How do you calculate the class width if you have a data set of 70 entries and you are asked to construct a 6 class frequency distribution?

I divide 70/6=11.66666, I round it up to 12; the class width is 12.

I divide 6/70=0.875, I round it up to 9; the class width is 9.

I choose a class width of 10 because it looks fine.

As there are 70 entries, each class width is 6.
