4 The formula is sum of scores divided by number of scores.
91. The sum of all scores is 728, and then dividing by 8, the total number of quizzes, the quotient is the answer.
9;9;9 Mean = sum of scores / number of scores = 9+9+9 / 3 = 27 / 3 = 9 another example is 7, 9, 11 8, 9, 10 etc even: 7, 8, 12
Example:Problem:Cheryl took 7 math tests in one marking period. What is the range of her test scores?89, 73, 84, 91, 87, 77, 94Solution:Ordering the test scores from least to greatest, we get:73, 77, 84, 87, 89, 91, 94highest - lowest = 94 - 73 = 21-The range of these test scores is 21 points.so:find the range for each list of scores80,79,85,75,84,76,88,8075,76,79,80,80,84,85,88highest - lowest = range88 - 75 = 13hope this helps :)http://www.mathgoodies.com/lessons/vol8/range.html
The sum of four and the product of three and a number xxxx.
4 The formula is sum of scores divided by number of scores.
1694 you multiply 22 by 77
0 (Zero)
sum of scores: 24 mean of scores : 24/4 = 6 squared deviations from the mean: 9, 4,4,9 sum of these: 26 sample variance: 26/4 = 6.5
If 5 scores average 80, their sum is 400.If 6 scores average 83, their sum will be 498.The sixth score must be (498 - 400) = 98% .
If, by SX, is meant the sum of the scores, then the answer is 48/4 = 12
If the raw math scores are available for all of the students then you could probably apply a t test to the results. Alternatively you could use a Wilcoxon rank sum test. The difficulty you face is that, without a measure of the variability in the scores you cannot be sure that the difference in the means is due to actual difference or just variability. To get that measure you need th raw scores.
the sum of the scores divided by the number of scores submitted
You add the scores together and then divide by the number of scores. So if you rolled a dice and your scores were, 3, 5, 2, and 6 You would add these together, getting 16, and then you would divide this by 4 (because you have 4 scores) and so your mean would be 4 (16/4=4) sum of scores / number of scores = mean. Hope this helps.

V + W + X + Y + Z) / 5 = 89 (V + W + X + Y + Z + 95) / 6 = ? 89*5= the sum of the 5 test scores. therefore, (445+95)/6 is the new average. 540/6=90. Your average test score is 90
