The Morris water maze is used to examine spatial learning in animals. Mice, who are good swimmers, are placed in a large pool of water and must learn to find a clear platform located just under the water surface. The platform is their only escape from the pool. If they do not find the platform, they have to continue swimming until we take them out.
If we think that we may have some aberrant times, what is the best way to identify them?
A) create a boxplot
B) prepare a stem-and-leaf display
C) use a pie chart
D) calculate the variance

Creating a boxplot allows for easy identification of outliers or aberrant times in a dataset. It visually displays the spread of the data and any potential outliers or extreme values. Stem-and-leaf displays are more useful for smaller datasets and do not provide as clear of a visual representation of outliers. Pie charts are not useful for analyzing continuous data like swim times. Calculating the variance may provide information about the spread of the data, but it does not specifically identify outliers.
