Statistics

I am posting the same question but in a different way. What width could I use for my histogram bars ? I would appreciate it. Sorry, for some reason my pictures are tilted.

The sides of your bars will be on the class boundaries (same issue as your previous thread as to where exactly those are) and for a histogram there are no gaps between the bars.

So, what do you think the width of your classes should be?

I used the upper class boundaries. For example, I did 20.5 first then 22.5 etc.

Those class boundaries are determined by assuming that data is rounded to the nearest integer. And class width, which is what you were asking about is 2; as it would be even if you were rounding down to the highest integer less than or equal to the value.
