Describe the distribution of the somatic cell count scc. (5 marks)

b) Using a boxplot, histogram and the descriptive statistics (mean, min, max, median, and quantiles).

Describe the distribution of the log of the somatic cell counts scc. (5 marks)

c). Using a boxplot, histogram and the descriptive statistics (mean, min, max, median, and quantiles).
