Figure 7-7: Frequency distributions created using the FREQUENCY function.
Using formulas to create a frequency distribution
Figure 7-8 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) qualifies for a B.
The formula in cell G2 that follows is an array formula that counts the number of scores that qualify for an A:
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
