\begin{question}
In the following figure the distributions of a variable
given by two samples (A and B) are represented by parallel boxplots.
Which of the following statements are correct? \emph{(Comment: The
statements are either about correct or clearly wrong.)}
\setkeys{Gin}{width=0.7\textwidth}
\includegraphics{boxplots-002}
\begin{answerlist}
\item The location of both distributions is about the same.
\item Both distributions contain no outliers.
\item The spread in sample A is clearly bigger than in B.
\item The skewness of both samples is similar.
\item Distribution A is right-skewed.
\end{answerlist}
\end{question}
\begin{solution}
\begin{answerlist}
\item True. Both distributions have a similar location.
\item True. Both distributions have no observations which deviate more than 1.5 times the interquartile range from the box.
\item True. The interquartile range in sample A is clearly bigger than in B.
\item True. The skewness of both distributions is similar, both are about symmetric.
\item False. Distribution A is about symmetric.
