Question

What is the mean and the median??

Answer 1

Answer:

Step-by-step 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.*

Hope I helped :)

The mean is where you add all the numbers in the data and divide it by the number of numbers there are in the given data. The meidan, you have to put all the numbers from smallest to largest and then cross of each number on each side. If, there is 2 medians then you add them together and divide it by 2.
