To calculate the average of the test score 90, you would need at least one more score for comparison. However, if 90 is the only score, the average is simply 90. If additional scores are provided, you would sum all the scores and divide by the total number of scores to find the average.
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

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.
recess does improve test scores.
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 !!
