Clojure for Data Science

Descriptive statistics

Descriptive statistics are numbers that are used to summarize and describe data. In the next chapter, we'll turn our attention to a more sophisticated analysis, the so-called inferential statistics, but for now we'll limit ourselves to simply describing what we can observe about the data contained in the file.

To demonstrate what we mean, let's look at the Electorate column of the data. This column lists the total number of registered voters in each constituency:

(defn ex-1-6 []
  (->> (load-data :uk-scrubbed)
       (i/$ "Electorate")
       (count)))

;; 650

We've filtered the nil field from the dataset; the preceding code should return a list of 650 numbers corresponding to the electorate in each of the UK constituencies.
