Thread: data entry and histograms

Hi;
I need to make a histogram on a ti-83 but don't know where to start.


The data I have is as follows.

class boundaries frequency
99.5-104.5 2
104.5-109.5 8
109.5-114.5 18
114.5-119.5 13
119.5-124.5 7
124.5-129.5 1
129.5-134.5 1
Thanks.

Thanks.

You can't enter intervals, you will need to enter the midpoint of each interval instead.

Ok thanks what do I do with the frequencies.

Ok getting somewhere select histogram xlist(is the data in L1) freq(frequencies contained in L2) got that.

but wont display graph which is selected on.

Not sure why?
