A cost spreadsheet shows unit costs in B2:B5 of 12, 15, 9 and 14. Cell C1 contains the formula =IF(AVERAGE(B2:B5)>12,"Review","OK"). What does C1 display if the value in B4 is changed from 9 to 13?

C1 displays Review. After B4 changes to 13, the four unit costs total 54 and average 13.5. This exceeds the test value of 12, so the IF condition is true and returns the text Review rather than OK.

Explanation

Originally the average is (12+15+9+14)/4 = 12.5, which is already above 12. After changing 9 to 13, the total is 54 and the average is 13.5. Since 13.5 is greater than 12, the IF test is true and the cell shows Review. OK would arise only if the average were 12 or below.
