Just need answers to questions C and D ..

Question A: Describe any distinctive features, including the shape, of the distribution for the variable age. (Third time is a charm!)

Mean =25.0167 and Median = 22.5

So mean > median and thus distribution should be right skewed.

Question B:

Fences are given by-

Upper fence = Q3 + (1.5 * IQR)

Lower fence = Q1 – (1.5 * IQR).

IQR is given by Q3 - Q1

So upper fence = 41.5 and lower fence =5.5

PART C & D

Question C: Does your graph (boxplot) support the distribution shape you reported in Question A? How do you know-? Explain.

Question D: Does your graph (boxplot) support the existence or non existence of outliers? Compare your findings to your answer to Question B.

column n mean variance std. dev. Std. err. median range min max Q1 Q3 age 60 25.016667 73.101412 8.5499364 1.103792 22.5 48 17 65 19 28 Ages of FLCC Students age

Explanation / Answer

Question C - Yes, the box plot supports the distribution of the shape. The boxplot have whiskers that extend more towards the right, which indicates that the distribution is right skewed.

Question D - The graph supports the existance of outliers

Upper fence is 41.5. But the maximum value is 65. The three dots in the right side indicates that these three points are beyond the upper fence of 41.5 and hence, these points are outliers.
