Important note: The explanations on the interpretation of the confidence intervals for the variances/standard deviations of the random effects (random intercept, random slope) are not correct in the video, as these can never actually include 0 (because they cannot become negative). In my opinion, it makes sense to look at these CIs, but rather for the qualitative assessment of the range of the estimate, not for the statement significant yes/no.
