  Question A: Describe any distinctive features, including the shape, of the distribution for the variable age.

Summary statistics:

Question B: Calculate (by-hand) the upper and lower fences for the data resulting from the variable age using the appropriate descriptive measures generated by StatCrunch. According to your calculated values of the upper and lower fences, are there any outliers in this data set? Please be specific.

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

Solution- A. Mean =25.0167 and Median = 22.5

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

B. Fences are given by-

So upper fence = 41.5 and lower fence =5.5

C. Yes boxplot does supoort the right skewed distribution as quite visible from the concentration of values at the smaller frequency.

D. Yes there is a presence of one outlier greater than 60.

TY!
