  Mean = 1505, standard deviation = 339</p>
  <p><strong>Male</strong><br />

  <p>I don't think the average rating of men and women is a relevant statistic at all. For starters, female players are on average much younger, so we should correct for that.</p>

  <p>He makes a very good point.</p>
  <p>A fairer comparison would be to look at mean and standard deviation for the two sexes for the U20, 20-50 and over 50 age groups, roughly juniors, adults and seniors</p>

  Here are the statistics from the latest (February 2023) FIDE rating data:
  
  **Female all ages**  
  Mean = 1478, standard deviation = 336
  
  **Male all ages**  
  Mean = 1644, standard deviation = 346
  
  **Female U20**  
  Mean = 1282, standard deviation = 237
  
  **Male U20**  
  Mean = 1356, standard deviation = 279
  
  **Female 20-50**  
  Mean = 1614, standard deviation = 318
  
  **Male 20-50**  
  Mean = 1690, standard deviation = 330
  
  **Female over 50**  
  Mean = 1644, standard deviation = 357
  
  **Male over 50**  
  Mean = 1761, standard deviation = 300
  
  So, David was right. The difference between the "all ages" means is about 165 but when these statistics are calculated by age range the differences decrease.
  
  For U20 the difference is about 75.
  
  For 20-50 it is also about 75.
  
  For over 50 it opens up to just over 115.
