Answer:
Explanation:
The values are: 8, 4, 1, 9, 3, 6, 3, 5, 12.
Mean
To find the mean, you first must add up all of these numbers:
The sum is 51. Then, you have to divide it by the amount of numbers that you just added, which is 9.
51/9 = 5.667
Your mean is 5.667
Median
To find the median, we first have to order the numbers from smallest to largest:
1, 3, 3, 4, 5, 6, 8, 9, 12
Then, all you have to do is find the number in the middle. You can choose to eliminate one number on each side in order to do this:
3, 3, 4, 5, 6, 8, 9
3, 4, 5, 6, 8
4, 5, 6
5
Your median is 5.
*Note: if you happen to have 2 numbers in the middle, you just add the two numbers and then divide by two.*
