Kurtosis is critically important and it's not typically discussed in entry- or even intermediate-level statistics courses. So happy to see you covering it here, your content deserves an Olympic gold medal. Thank you so much

Skewness measures the degree of asymmetry of the distribution, while Kurtosis measures the degree of peakedness and flatness of a distribution

Very good. A slight clarification though: heavy tails does not necessarily mean "a lot of outliers." A single observation that is 7 standard deviations from the mean is enough to indicate a heavy tail. After all, such an observation would not happen, for all intents and purposes, under normality. The tails of heavy tailed distributions, while much higher than normal tails, are still very close to zero.

Problem with these higher moments is with their sensitivities to outliers. How much more data we need to "reliably" estimate these (ever-increasing) higher moments?

I think the full distribution in visual form is the best for non-technical audiences. Then you don't have to dumb down and you don't have to explain it much either. If graphs are forbidden for some odd reason, maybe "buckets" can be a good way. Like 20% of the students had less than 30p, 30% in range 30-50p etc. Honestly even standard deviation is tricky to understand even for technical people. Ask someone who "should know" to explain - on the spot - the difference between standard deviation and the mean deviation.

One thing that kills me is when, like in the video example, the blue distribution is skewed to the left, my brain wants to understand as the other way around, e.g, 'to the right', because that is what the figure looks like, as if it was 'pending to the right'. D:
