So, I've been absent for the last couple of days from school and I got my homework and I don't understand it! Could you point me in the right direction?

Here's an example problem:

"The Following data represent the mass measured (in gram) of a certain mineral in a geology laboratory:

A. Prepare a frequency distribution

B. Create: a histogram, a polygon of frequency and an ogive

Is a frequency distribution something like a table where I can show something like

mass ===> total

30 - 39.9 ===> 6

Thanks!
