Calculate (1) sample mean, (2) sample variance, (3) standard error of the mean, and (4) use bootstrapping to calculate other important analysis of uncertainty in statistics.
A1: great question!
Q: fave type of tree?
A1: Princess Flower
Q: why were there arrows with mu and sigma on slide 17? does that mean something intuitively?
A1: I’m not seeing the arrows on my copy of the slides. You mean in the first slide after the watermelon slide?
A2: On one of the slides there were arrows overlayed over the PMF with arrows going up for mu and accross for sigma
A3: Ah, in the diagram… those are just visual to show you the location of the mean and that the standard deviation is a measure of left-to-right spread. It’s just a visual cue and nothing else.
