Explain in math 8th grade - what mean, median and mode are?

Mean - is the average of something. You basically find the sum of all the numbers then divide the sum by how many numbers you added so for example I have 1,3,4and 2
To find the average you add them first to get 10 then you divide this by 4 since I added 4 numbers.

Median - is the number that falls in the middle. First you gotta sort the numbers from smallest to biggest then pick the one in the middle for example is I have 7,5,9,2and 1. I gotta sort it —-> 1,2,5,7,9 then I pick the number in the middle which is 5. So 5 is the median

Mode- is the number that appears the most times. So if I have the set 3,7,5,3,9,4,1,3 the mode would be 3 because it appears the most times

Mean is the average

To calculate mean
Eg: 2, 5, 9, 3, 5, 4 7
There are 7 digits
(2+5+9+3+5+4+7) divide by 7
= 5 is the mean

Median is the middle value

To calculate mean, you have to reorder the data in a numerical order. Median is always the middle value so in this case: 5 is the middle value.

2, 5, 9, 3, 5, 4, 7
Ordered correctly: 2,3,4,5,5,7, 9
=5 is the median value

Mode is the most repeated number on the list, so for this care, the Mode is 5 because there are two “5” digits in this data.
