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"? --Joshualouie711talk 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)
