Univariate data

We are now ready to start playing with the data. A good way to get an initial feeling of the data is to create graphical representations with the aim of getting an understanding of the shape of its distribution. The word distribution has a technical meaning in data analysis, but we are not concerned with this kind of detail now. We are using this word in the informal sense of how the set of values in our data is distributed.
