Here are the lengths (cm) of Red Pine needles taken at random: Growing in Sudbury Growing in Killamey Park Summarize in a figure and comment on the distribution of the observations. What do measures of central tendency indicate about the distribution? Is the sample size adequate?

Solution

5

a) Growing in Sudbury

This corresponds to the fact that on the bar graph, the bars get shorter as we look from left to right. A distribution that has those properties is called skewed to the Right.

8.5

mean > median > mode

Growing in Killernry Park

Mode> Mean>Median

c) No, the sample size is not adequate because we donot conclude that which data follows which distribution

Mean	9.7
Median	9.4
Mode	8.5
