What is the mean, mode and median for 2,7,3,7,9?

Mode: 7, Median: 7, Mean: 5.6

Median:  
First, we put it in numerical order:

2, 3, 7, 7, 9

Then we crossed out the two on the sides:

3, 7, 7

Then we do it again...

7

Then we are left with 7! So the median is 7!

Mode:
Mode is most common number in the group of number so the number that appeared two times is 7.  So the mode is 7.

Mean:
We add all numbers together:
2+7+3+7+9 =28

Then we divide that number by the number of numbers we have:
28/5 = 5.6.
