THE SUMMARY OF THE ANALYSIS (So far) As some of you know, I did a bit of statistical analysis lately regarding this question. In a previous thread, I focused on the top 50, using ATP points (as of June 4th) as a measure of players' success on the court. I tested the statistical significance of the difference between the average points gathered by each backhand group. The conclusion I reached was that there existed a statistically significant advantage for a two handed backhand within the scope of the top 50. However, as I warned people originally, there are limits to every analysis. I won't list them all here, but I looked for different ways of interpreting the results I got, searching for other correlations within the top 50. I did find something interesting: the top 10 seemed to heavily bias the test I performed. Because of the elitist point system of the ATP, the weight of the top 10 was much greater than any other ten ranks segments in the top 50. Following this observation, I computed the correlation coefficients for each segment of ten ranks and, overall, you can find the opposite relationship: as you get further away from the top 10, the one handed backhand actually seems to become an advantage (I did not test the statistical significance of this correlation, so I've only used it to decide what I would be looking for). So, I tried to go around the elitism of the ATP point system to see what we would get. I attributed a score ranging from 50 to 1, going from the top player to the 50th player, and I produced a new test. The result is very different: if you set aside the point system of the ATP and just bother about where you'll be in the ranking system, there exist no statistically significant advantage in using either a two handed backhand or a one handed backhand. DISCUSSION I could expand the scope of this analysis to make it more useful to settle this debate. However, upon what I have found, I would make the hypothesis that the difference between both strokes is not statistically significant in general. Beyond the top 20, the coefficient of correlation between your backhand type and your ATP points is either roughly null or slightly favorable to the one handed backhand. If the tendency is maintained throughout lower rankings, we could get to a point where we'd definitely claim either way is good.
