To find the score needed on the last test to achieve an average of 88, first calculate the total score required for four tests. An average of 88 over four tests means a total score of 88 × 4 = 352. The total score from the first three tests is 84 × 3 = 252. Therefore, the last test score must be 352 - 252 = 100.

To find Stacey's first test score, we can use the formula for average: (sum of all scores) / (total number of scores). Stacey's total score on three tests is 84 x 3 = 252. Her last two test scores total 79 + 93 = 172. To find her first test score, we subtract the total of the last two tests from the total score: 252 - 172 = 80. Therefore, Stacey's first test score was 80.
To find out what Melinda needs on her third test to maintain an average of at least 90, we first calculate the total points needed for three tests. The average is determined by dividing the total score by the number of tests, so for an average of 90, she needs a total score of at least 270 points (90 x 3). With her first two test grades of 87 and 94, she has 181 points so far. Therefore, she needs to score at least 89 on her third test (270 - 181 = 89).
It is above the average of 100, or the average spread which is 90 to 110. That is usually taken as "good". Of course, what kind of IQ test is a factor. And how valid IQ tests are is a factor.
The average IQ for all people at all ages is a standard score of 100. The average range for some tests (such as the KABC-2) includes standard scores from 85 - 115. For some tests (such as the WISC-IV, WPPSI-III, WAIS, WNV, SB5) is 90 - 109. Either way, 100 is dead average.

The average score on an IQ test is about 100. If you score higher than that, your score will be above average.
This depends on what kind of average score you are asking for. To find the average score on a test, you will need to take the scores from all the tests and divide them by the total number of tests.
