All of these data points are zero, while these, they change a good bit from data point to data point. So we have a sense that there is more variability in this data set. Now one of the things we will start doing a lot in statistics is trying to measure how much more, how much variability is, how can we quantify that? How can we put a number on it? How can we measure variability? This is a big aspect of statistics, but we won't do that in this video. There are future videos for doing that.
