FIGURE 14.6
Frequency distributions created by using the FREQUENCY function
Using formulas to create a frequency distribution
Figure 14.7 shows a worksheet that contains test scores for 50 students in column B (the range is named
Grades). Formulas in columns G and H calculate a frequency distribution for letter grades. The minimum
and maximum values for each letter grade appear in columns D and E. For example, a test score between
80 and 89 (inclusive) earns a B. In addition, a chart displays the distribution of the test scores.
The formula in cell G2 that follows is an array formula that counts the number of scores that qualify for an A:
=COUNTIFS(Grades,”>=”&D2,Grades,”=D2)*(Grades
