How do you find range to estimate a sum?
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

What is the level of measurement for the mean math scores of students who take math in the morning compared to those who take math in the afternoon?
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.
What is a median score?

What is the trick for calculating mean. I mean some decent trick to make me do it in my head?
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.

If average test scores are 89 and then a sixth test score is 95 what is new average?
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
