In this lesson, we are going to be talking about the transformations of data. First we are going to talk about why we even transform data and then we are going to talk about two different broad types of transformations, shape preserving and shape changing transformations. Then we will talk about some common shape changing transformations that you might need to know. Some of them you already know. Later on we will move on to log transformations to see when we need to change one variable and when we need to change both of them.
