Advanced Counting Formulas
Figure 7-8: Creating a frequency distribution of test scores.
The formula in cell G2 that follows is an array formula that counts the number of scores that
qualify for an A:
{=SUM((Grades>=D2)*(Grades<=E2))}
You may recognize this formula from a previous section in this chapter. (See “Counting cells that
meet multiple criteria.”) This formula was copied to the four cells below G2.
The formulas in column H calculate the percentage of scores for each letter grade. The formula in
H2, which was copied to the four cells below H2, is
=G2/SUM($G$2:$G$6)
Using the Analysis ToolPak to create a frequency distribution
After you install the Analysis ToolPak add-in, you can use the Histogram option to create a
frequency distribution. Start by entering your bin values in a range. Then choose Data
Data Analysis to display the Data Analysis dialog box. Next, select Histogram and click OK. You
should see the Histogram dialog box shown in Figure 7-9.
