The resulting graph visualizes the overall result of the two test conditions in form of a boxplot[fn:boxplot]: the average task times in the \emph{tagstore} condition and the folders condition.

The label keyword above created a reference to Figure \ref{fig:boxplots}

Every single step from the raw data from the \myacro{CSV} file to the graph can be completely checked and re-created by anybody who wants to do so. This method of Reproducible Research guarantees the highest level of transparency and confirmability.
