Interpret differences in shape, center, spread, and outliers in context.
Classify the shape of a dot plot
Problem
Classify the dot plot with counts \({1:4,2:3,3:1,8:1}\). Report its modality and shape, identify any gap, calculate \(Q_{1}\), \(Q_{3}\), \(IQR\), and the upper fence, and identify any outlier.

A
modality=unimodal with mode1; symmetry=symmetric about3; gaps=no values from4 through7; quartiles Q1=1,Q3=2.5,IQR=1.5, upper fence4.75; outlier=8
B
modality=unimodal with mode8; skew=left-skewed; gaps=no values from4 through7; quartiles Q1=1,Q3=2.5,IQR=1.5, upper fence4.75; outlier=none
C

D
modality=all values tied; uniformity=uniform; gaps=no values from4 through7; quartiles Q1=1,Q3=2.5,IQR=1.5, upper fence4.75; outlier=none despite8
