Frequency distribution chart

Can someone point me in the right direction to get the chart made? The materials i was given dont make much sense to me.

You are the production manager for an operation that produces circuit boards. Each board is tested at the end of the manufacturing process. Rejected boards are discarded and have no future value. For product B-17, you have kept data on the number of rejects for the past 38 weeks. These data are:

Number of rejected boards.

I can find information on frequency tables, histograms, and polygons, but not "charts", so I'm not sure how to advise. However, in general, it appears that one starts with a table.

In your case, you would pick intervals for the numbers of items, and then count how many weeks had totals within those intervals. :wink:
