Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Why yeeeeesssssss, I haaaaaaaave. Remind me how that matters at all, considering we are talking about the specific selection that is being made? Here, since I was already using wikipedia as a source:

Selection bias is the bias introduced by the selection of individuals, groups, or data for analysis in such a way that the association between exposure and outcome among those selected for analysis differs from the association among those eligible`

Note that selection bias is when you are sampling. We're not talking about a sample here, we're talking about the entire population. In statistics, we call that a parameter. It's generally rare that you can accurately determine a parameter, but since the amount of people who have tried to summit everest is so small, and records have been pretty good (aye, we're certainly missing a few), that 400/13000 number is pretty damn close.

My point is that the number of people who attempted Everest is so low, because the only people who attempt it are those who are very very good, and confident in their skills. So yes, of course the % is going to be relatively high.
