So let's look at the two data sets. This has 10 times the standard deviation. Which makes sense intuitively. I mean, they both have a 10 in here, but each of these guys, 9 is only 1 away from the 10, 0 is 1 away from the 10. So the standard deviation is 10 times the standard deviation. So the standard deviation, at least in my sense, is giving a much better sense of how far away, on average, we are from the mean. Anyway, hopefully you found that useful.
