Answer by oberobic(2304) (Show Source): You can put this solution on YOUR website!
To raise your current average, you must add a score higher than the average. Similarly, if you add a score lower than the current average, you will lower your average.
.
Given you current average is 86,
Adding a score of 73+5 = 78 will lower the average, while adding a 97 will raise the average.
.
The magnitude of the effect will depend on how many observations have be included in the current average and how great the difference is between the score being added and the average.
