For this I'm using the tabs from the recent National Law Debates in Galway and from the Cork IV in December. This is as they are the two most recent tabs I have and I am confident that I was able to identify female names from male names (I wouldn't be so confident with a Worlds or Euros tabs). I also used the total speaks for the competition, not the individual speaks. I could make up some valid reason, but it's 99% because I'm lazy and it's easier to work with.
IV | Male Mean | Male Standard Deviation | Female Mean | Female Standard Deviation |
---|---|---|---|---|
Cork | 362.2577 | 28.45621 | 361.3617 | 25.18145 |
Galway | 372.2174 | 21.89606 | 370.8286 | 23.90482 |
What does this teach us? Apart from the fact that judges at Galway were more generous, it clearly shows that there is no meaningful difference between an average male or female speaker. The boxplot of the cumulative results from both IVs also shows this in a nice visual way. It also shows that the 25% and 75% quartiles lie essentially at the same point, showing that the distributions are essentially the same. A t-test gives the probability of there being no difference in the actual means as 0.772; for there to be a statistically significant difference, that number would have to be less than 0.05.
So one thing is abundantly clear from this; there is no discernible bias towards male speakers from judges. One thing that has to be remembered here though, is that these were all mostly Irish judges. My own admittedly stereotyped view of the world would suggest that a bias is more likely to exist in not-so-liberal countries and thus would be more prevalent at Worlds (this is the angle I'm selling to try to get a research grant).
Where a difference does appear is in participation numbers. In both IVs the proportion of male to female speakers is approximately 2:1 (32.7% female in Cork, 33.6% male in Galway). Given the small total sample size, the 95% confidence interval (i.e. the range of possible values) for the true proportion of female debaters is between 27.3% and 39.35%. Clearly this is where there is a problem.
As a white, heterosexual, private-schooled male (and thus not part of any oppressed minority), I'm not going to spend too much time discussing the various options available to the debating community to help solve this problem. Just to say that when it comes to participation, I think the onus is much more on the individual societies to up their game in recruitment, training and retention than on changing the rules of the game. There clearly is nothing wrong with the game itself which handicaps women.
