Question

10 ways to calculate mean mode and median

pls answer me

Answer 1

To find the mean, sum all the numbers and then divide by the number of items in the set. For example, to find the mean of the following set of numbers: 21, 23, 24, 26, 28, 29, 30, 31, 33
First add them all together:
21 + 23 + 24 + 26 + 28 + 29 + 30 + 31 + 33 = 245
Then divide your answer by the number of items in your set. There are 9 numbers, so:
245 / 9 = 27.222


Mode is the most common number in a set. For example, the mode in this set of numbers is 21:
21, 21, 21, 23, 24, 26, 26, 28, 29, 30, 31, 33


Mean is the middle number in a data set. To find the median, list your data points in ascending order and then find the middle number. The middle number in this set is 28 as there are 4 numbers below it and 4 numbers above:
23, 24, 26, 26, 28, 29, 30, 31, 33

Note: If you have an even set of numbers, average the middle two to find the mean. For example, the mean of this set of numbers is 28.5 (28 + 29 / 2).
23, 24, 26, 26, 28, 29, 30, 31, 33, 34

ther are not 10 ways to find it....but i hv given you one....Hope it helps!!
