Question

what does mean, median, mode, and the other word mean

Answer 1

Mean: add all the numbers and divide by the number of numbers
    so if I had 1, 2, 2, 3, 4, I would add all of them together and get 12 then divide 12 by 5 because there are 5 numbers to get a mean of 2.4

Median: the middle number in a set
     in the set 1,  2,  2,  3,  4 the median would be 2 as it is in the exact middle of the set of numbers. ***Be careful! For this, the numbers HAVE to be in numerical order so it has to be 1, 2, 2, 3, 4   NOT something like 1, 2, 3, 2, 4

Mode: the number that appears the most in a set
     in the example 1, 2, 2, 3, 4  the mode is 2 because 2 appears more than the other numbers

Hope this helped!! 

Answer 2

so mean is when you add all the number you have and divide it how many number.

example: 1,4,5.6 if you add all the numbers the answer will be 16 and divide it 4 so you count how many number you have so 16 divide by 4 = 4.

the median is the one that are in the middle . to find it you have to place the number to least to greater and find the median.

Example:     4,6,10.5,3,1,8

so least to greater will be 1,3,4,5,6,8,10.  so when you count the median will be 5 because you count 1,3,4 and you count 6,8,10 so the middle is 5.

the mode is the number that occurs most often in the number like this

Example: 1,2,3,3,4,5, so the number that occurs most often is 3 .
