In this lesson, we are going to be starting to talk about normal distributions. We will talk about normal distributions in the next couple of lessons as well, and it will come up again and again in the future. It is a pretty important one. First we will talk about what a normal distribution actually is. We need to distinguish it to what we have been talking about before. We are also going to talk about how there are lots of normal distributions yet they all have the same shape and what that means. Then we are going to talk about some normal distribution problems but only problems that use the what we call empirical rules.
