Is my taste in music sexist? I noticed as I listened to the new Rough Trade "Best of 2019" list (https://www.roughtrade.com/us/albums-of-the-year-2019-top-100) that I was often giving female singers lower scores than male singers.

Rating Number Male Female
10 6 4 2
9 5 4 1
8 15 10 4
7 12 9 3
6 17 11 6
5 11 7 4
4 16 9 7
3 9 6 3
2 7 4 3
1 2 2 0
100 66 33

So, since I love statistics, I wanted to test that theory. My ratings follow a normal distribution quite closely (skewness=-0.0309 and kurtosis=-0.8327, which is pretty good). However, given my average album score of 5.73, I gave men an average rating of 5.88 and women a lower rating of 5.48.

t-value 0.6122992 0.6298863

My hypothesis is that my average rating for female singers of 5.48 is too far from the norm to be expected by chance. This gives a t-statistic of T = (pbar-p0)/(s/sqrt(n)) or (0.573-0.548)/(2.28/(33^0.5)). This equals 0.063. A two-tailed 5% p-value for 32 degrees of freedom is 0.950158, and that is much greater than 0.05, so my hypothesis is rejected. In other words, my average rating for female singers is NOT too far from the norm (at p < 0.05), at least I think so if I did the math correctly.

However, looking at my trending chart for "Ratings by Sex", I can see that at lower ratings, the percentage of female singers goes up. So, yes, I still worry that I am sexist, but not by a statistical significance.
