What we're going to do in this video is start to compare distributions. So for example here we have two distributions that show the various temperatures different cities get during the month of January. This is the distribution for Portland, for example they get eight days between one and four degrees Celsius, they get 12 days between four and seven degrees Celsius, so forth and so on, and then this is the distribution for Minneapolis. Now when we make these comparisons, what we're going to focus on is the center of the distributions to compare that, and also the spread. Sometimes people will talk about the variability of the distributions, and so these are the things that we're going to compare. And in making the comparison, we're actually just going to try to eyeball it. We're not gonna try to pick a measure of central tendency, say the mean or the median, and then calculate precisely what those numbers are for these.
