Statistics:the link provided suggest to pay to discover why the five articles: arithmetic mean, standard deviation, histogram, confidence interval and standard error are probably not useful to beginners. Another method is to read the articles themselves! Pldx1 (talk) 17:20, 25 May 2018 (UTC)

Statistics again. Concerning standard error, the situation is even worse. Painted with a large brush, the problem is as follows. You have a sample, and you compute $m,s$. Therefore $m,s$ (the mean and the deviation of the sample) are known fixed numbers. But your aim is $\mu ,\sigma$ (the mean and the deviation of the population). Therefore, you imagine what would happen if a large number of samples were drawn (at random). All the $m_{i}$ are now instances of another random variable, having its own mean $M$ and deviation $S$. But, as before, the only things you know are $m,s$: dreaming don't increase your knowledge. So you use $m$ to guess either $\mu$ or $M$ and you use $s$ to guess either $\sigma$ or $S$. And now, your problem is as follows: how sound is using your $s_{1}$ to guess how far is your $m_{1}$ from its target $\mu$ ? Exercise: what is the major difficulty here (not even mentionned in the article) ? Pldx1 (talk) 09:49, 26 May 2018 (UTC)

• "Results show that leaks of engagement at each step of the pipeline actually exist: 83% of internet users actually visited Wikipedia, while 68% only of users knows that Wikipedia is editable." Do you mean "only 68% of users know"? --Joshualouie711^talk 00:14, 26 May 2018 (UTC)

• Thanks for the summary of recent research. I enjoyed reading it! Rachel Helps (BYU) (talk) 20:35, 4 June 2018 (UTC)
• The concerning points out of the selected literature are that there's a false belief that we need more participation at Wikipedia and that of those that do participate, some number are doing so to WP:RIGHTGREATWRONGS. Chris Troutman (talk) 21:40, 6 June 2018 (UTC)
