If there was a shoe that I liked but it also had some padding in the sole(and a thick heel) that would also make me look taller; would you look down on me if you thought I was 5'10''ish and turned out to be 5'8''ish? It's weird asking this question because no one has mentioned my height and a lot of guys give themselves 1-2 inches anyway but I know women/girls think about it. California surveyed men at age 18 and the average was 5'9.6" with a deviation of something like 1.2-1.4. I'm in STAT 1220 so 66% of men are between 5'8.3'' to 5'10.9'' or within one standard deviation of the average. <------just for noobs. Height is a good example of continuous random variable.
