Examples of mean, median, and mode
valina [46]

Answer:

in a group of numbers (2,4,7,9,7,5,7,8,3)

The mean would be 5.2

The mode would be 7

The median would be 7

Explanation:

Say we have a group of numbers<u> (2,4,7,9,7,5,7,8,3)</u>

Lets start by finding the Median! *Remember, the median is the MIDDLE!

So, if the median is the middle, it would be 7.

Lets do the mode now. *Remember the mode is the one that happens the MOST!*

If we take a look at the numbers, we see that 7 occurs the most (it appears 3 times)

Our mode would be 7.

Lastly, lets do the mean. *You add and divide for the mean*

So, we start by adding all of the numbers together.

Basically, ( 2 + 4 + 7 + 9 + 7 + 5 + 7 + 8 + 3) you then get 52.

Next, we divide 52 by all the numbers that we added together (9)

And we get our mean: 5.2
