A recent article in the Make-Believe Journal of Social Science states that "A large scale study concluded that Junior-high students who played dodge-ball had a lower weight compared to those who did not play dodge-ball".

The specifics of the test were:

n=30,000 Junior-high students in each group (those who played dodge-ball vs. those who did not). P-value= 0.0015

Average difference in weight= 20.0 pounds.
