36 What are the worst (commonly adopted) ideas/principles in statistics? 36 Confused about independent probabilities. If a fair coin is flipped 5 times, P(HHHHH) = 0.03125, but P(H | HHHH) = 0.5 33 Maximum Likelihood Estimation (MLE) in layman terms 33 Big disagreement in the slope estimate when groups are treated as random vs. fixed in a mixed model 26 Why is the marginal distribution/marginal probability described as “marginal”?
