Question

Approximate Height in Inches: Mean = 3012 Median = 69 Variance = 1226.5 Std. Dev. = 35.02 IQR = 7 Lower Quartile = 65 Upper Quartile = 72 Lowest = 5.4 Highest = 682 Boxplot 682 5.4 65 69 72

List 2 findings about the shape of the data and how it appears to be spread out in each of the quadrants.

Answer 1

Sol:

mean=70.2

median=69

mean>median

distribution is positively skewed.

range=max-min=682-5.4=676.6

no outliers seen from bxoplot

spread is less from Q1 to Q2 (69-65=4)

and also less from Q2 to Q3(72-69=3)

and is more from Q1 to Q3 (72-65=7)
