How to Make a Relative Frequency Histogram on Excel 2007

1. Create a column for your independent variables (your x-values). For example, if you are comparing the performance of salespersons, write 'Jim' in cell A2, 'John' in cell A3, 'Sue' in cell A4, 'Pat' in cell A5 and Joe in cell 'A6.'
2. Create a column with your dependent variables (your y-values). For the example given in Step 1, write 12 in cell B2,11 in cell B3,10 in cell B4, 9 in cell B5 and 4 in cell B6.
3. Sum the dependent variable column by clicking an empty cell at the bottom of the data and entering the summation formula. For the Step 1 example, you have information in cells B2 to B6, so the formula is =SUM(B2:B6).
4. Create a second set of y-values by calculating the percentage of sales for each item. Use a formula to calculate this for you; for the example given in the steps above, enter =B2/B7 in cell C2, =B3/B7 in cell C3, =B4/B7 in cell C4, and =B5/B7 in cell C5.
5. Click on the down arrow below 'Column' in the 'Insert' tab. Choose '2-D Column' from the menu.
6. Click on the column representing the total number of sales. Press the 'Delete' key. This action leaves you with the relative frequency distribution graph only.
