2.1 You are given n = 5 measurements: 0, 5, 1, 1, 3.

a. Draw a dotplot for the data. (HINT: If two measurements are the same, place one dot above the other.) Guess the approximate "centre."

b. Find the mean, median, and mode.

c. Locate the three measures of centre on the dotplot in part

a. Based on the relative positions of the mean and median, are the measurements symmetric or skewed?
