construct a frequency and a cumulative frequeny histogram based on the table below.

the range for the table are:1-10,11-20,21-30,41-50

The frequency is 2, 3 , 4,4,7,

I need to find the cumulative frequency then graph it , I know how to graph it

You have 4 ranges for scores, but 5 frequencies. What category (range) does the extra one go into (31-40)? In statistics, you need to pay attention to these details.

If they are in order, the first bar in the histogram for a

*cumulative* frequency will have a value of 2, the second 5, the third 9, and so on.

I searched Google under the key words "

*cumulative histogram*" to get these possible sources:

http://www.itl.nist.gov/div898/software/dataplot/refman1/ch2/histogra.pdf
In the future, you can find the information you desire more quickly, if you use appropriate key words to do your own search.

I hope this helps. Thanks for asking.
