Task 2: Perform descriptive summary of the variable write

a. Find the sample mean and sample standard deviation as well as the 5-number summary of the variable write.

b. Create a boxplot showing the distribution of the variable write. Comment upon the shape of the distribution, i.e., either symmetric, skewed to the left or skewed to the right. Use the whisker limits to determine whether any outliers present.

c. State which central measure (mean or median) would be best to use to describe the centre of this distribution and provide the reason(s).
