James's weekly quiz scores are shown in the stem-and-leaf plot below.

If he drops his scores from the first two weeks, his mode score increases by 2. How much would his mean score increase?

Perhaps you should answer some questions first, 

 

What is a mode?

What is his mode to start with?

 

What does the new mode need to be.

Which 2 scores need to be dropped?

 

What is the average score now?
