ASSIGNMENT 2 - ANALYSIS OF DATA 3 Question 2 - Summary of a metric variable The distribution of fruit eaten per day by Australians in a random sample of 2000 observations is displayed in Figure 1. The distribution is positively skewed with 50% of fruit eaten per day is 1. Typically, the amount of fruit eaten per day by Australians was between 1 and 2, with half the observations within this range. 6 observations had an exceptionally high amount of fruit per day of 5.
