How do I figure his current average?

**jim**, Saturday, October 17, 2009 at 10:31amForget his current average for a minute.

Now, what batting average does 8 hits in 28 make? (Divide 8 by 28.)

We don't know how that .308 was made up, but we know that if 8/28 is greater than .308, he's batting better than his past average, so the average will go up. Equally, if it's less, it will go down.

Example:

Joe hits 4 in ten games, average is .4 = 4/10.

Now Joe hits 1 in the next 5 games. Average for those 5 is 1/5 = .2, which is lower.

Now consider his whole average: hit 5 in 15 games = 1/3 = .333, so we can see how the average was lowered by that streak of 5 games.

**Anonymous**, Saturday, October 17, 2009 at 11:38am8 divided by 28 is .2857. If the current average is .308 then the average would go down not up, right?

**Did Jim leave?**, Saturday, October 17, 2009 at 12:18pmIf the current average is .2857 then it would have gone down from .308?

Yes! Not that the _current_ average is .2857, just that the average of the new games that are added on is .2857.

If Harry batted exactly .308 in the next 28, his average would stay the same, at .308. If he bats lower, the average will go down. If he bats higher, the average will go up.
