Three binwidths

Before you take these plots for granted, it's a good idea to see how things change when you alter the binwidth. The binwidth determines how smooth your distribution will appear: the smaller the binwidth, the more jagged your distribution becomes. It's good practice to consider several binwidths in order to detect different types of structure in your data.

Instructions

100 XP

Create the following three plots, adding a title to each to indicate the binwidth used:

  • A histogram of horsepower (i.e. horsepwr) with a binwidth of 3.
  • A second histogram of horsepower with a binwidth of 30.
  • A third histogram of horsepower with a binwidth of 60.
