data organisation (1 Viewer)

Hey
I have a data set that I need to organise into a frequency distribution table. The data consists of random numbers (it is not discrete, it's continuous data) and I was thinking of grouping the data into groups of like five. But then I got stuck with this:

Say the data was 2.75, 2.5, 2.8, 3.1, and 3

What I would have done is to organise that into 2-3 and then 3-4. But then I have two groups that cover three. How do I fix this?

Thanks
mitch

I can see why it's tricky because the data is continuous and up to 2 decimal places. Maybe try groups like 2.01-3, 3.01-4, 4.01-5, etc... which covers every possible 2 decimal number without overlapping.

I hope that helps.

think i might end up doing that,

thanks

Or something like :

2 < x ≤ 3
3 < x ≤ 4
4 < x ≤ 5, etc

and that sort of stuff. That would cover any value that would come up.
