Boxplots Outliers, how are there values outside of the minimum and maximum whiskers?

101 viewsMathematicsOther

I don’t know much about statics but looking at a boxplot there’s a minimum whisker to the left and a maximum whisker to the right. Then, there’s outliers laying outside of both whiskers.

If the minimum whisker marks the lowest value for the data, why are there values outside of the minimum or maximum whiskers?

Alright, imagine you have a bunch of toys in a box, and you want to see how heavy they are. You line them up from lightest to heaviest and draw a picture to show their weights. That picture is like a boxplot.

Now, most of your toys might be around the middle, with a few really light ones and a few really heavy ones. The box in the middle of the picture shows where most of the toys are. The line in the middle of the box is the “median” weight, which means half the toys are heavier and half are lighter.

The “whiskers” are like lines that show how far most of the toys go. The whiskers reach up to where most of the toys are, but they don’t show every single toy. So, if there’s a really, really heavy toy or a really, really light toy, it might be outside of the whiskers. These are called “outliers.”

Think of it like this: most kids might have toys that are not too heavy or too light, but there might be a few kids with really heavy or really light toys that are different from the rest. These outliers show up as points outside of the whiskers on a boxplot.
