Changes in mode

Look at this set of 8 numbers:

 4 7 6 7 3 2 2 2

How would the mode change if the number 7 replaced one of the 2's in the set?

 increase decrease no change

The mode is the number that appears most often.

Find the original mode. The number that appears most often is 2. So, the original mode is 2.

Now replace one of the 2's with 7.

 4 7 6 7 3 7 2 2

Find the new mode. The number that appears most often is 7. So, the new mode is 7.

The mode would increase from 2 to 7.
