Frequency Polygon

When making a grouped frequency table for the polygon if you had a number say 3 with a frequency of 7 and there were two groups 1> x >3 and 3> x >7 which group would it go in the first or the second?

Neither: this scenario should never occur. One group should always go to less than or equal to, or more than or equal to. For instance, group 1 would be
1<x<=3 <= is less than or equal to
3<x<7

In which case it would go in the first group.

No problem.

Just in case this wasn't a one-off: in your original post you got the limits the wrong way round. 1>x>3 implies x is greater than 3 and less than 1 which is impossible - you want 1<x<3 (or "less than or equal to") :smile:
