4 The formula is sum of scores divided by number of scores.
An average is worked out by dividing the total of the scores by the number of scores. You have 4 scores already so when you have done the next test it will be 5 scores. If you multiply 5 scores by 90 it gives you a total score of 450. The 4 scores you already have adds up to a total of 354. If you subtract 354 from the 450 you get 96 and that is your target for the final test. The average for the first 4 tests comes out at 88.5

recess does improve test scores.
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.
They cannot. Test scores are either marks or percentages based on marks (out of the total) and so are discrete.
There may be a correlation between the presence of a library and higher test scores
To get better scores on the Test you must better know the material on the test prior to taking it.
I seem to remember seeing that homeschoolers had higher scores. Correct !!
Chicago schools have the lowest test scores.)~:
