Below
is the hitting profile circle graph of the Yankee slugger.

Make a similar graph for his 2006 statistics. Here's what you do.
Download the Sketchpad
file.
(See above.)
Notice that the slices are determined by the size of the angle it
makes. To find out his home run slice angle:
- take the number of home runs he hit in 2006 (35) and
divide by the total number of at bats (572).
- This gives you the percentage of home runs to at
bats. (6.1%)
- Since one complete rotation is 360 then 6.1% of 360
will be Alex's home run slice angle which is 21.96 or rounded up to 22
degrees.
- Adjust the angle accordingly on the Sketchpad sketch.
- Repeat this for:
- singles
- doubles
- triples
- outs
- Compare
the new graph to the 2005
one. How is it different?
- Why is the
size of the making an
out (the green one) so much bigger than any of the other slices?
- What would
be a player's batting
averagebe if 50% of their circle is shaded green?
- Why?
