Transcript of Histograms and Polygons Problem 24 page 42. Here I copied the data created in the other section....
Here I copied the data created in the other section. Notice how I put the labels. I put Frequency instead of total.
Here I added other columns we will need to make our histograms and polygons.
Notice the midpoint is really half way between the two values defining the class. Take the range, divide by 2, and add it to the lower value to get the midpoint.
Go to insert on the main menu and scroll to chart.
Click this box and then get the data in the Percent column – without the label or the total. Then click the box to return. Our data is in columns so make sure that is clicked. Then click next.
To get a polygon go back to insert chart. Click on the Line Chart Type and pick the sub type as shown. At this you point follow the same directions as for the histogram (except you will not have to shrink spaces between bars).
