Because you can compare the values easily, for instance, you can compare the highest and lowest value and compare this to the mean, does the highest and lowest value differ greatly from the mean? Then you know the correlation is a bit unpredictable, you can also use this to compare two box plots, putting them together you can see through the median and quartile range the best way to do something, etc.
never, you will never use it
No because box and whisker plots are related to cumulative frequency curves
Nothing. Most box and whisker plots do not have 88 on them!

it is absolutely cazy and stupiddunno

On a standard box-and-whisker plot, the averages used are medians. Arithmetic means are used in some box-and-whisker plots, but most use medians.

Yes, I believe they can.
Parallel box and whisker plots are regular box and whisker plots, but drawn "one-above-the other" on the piece of paper. To enable to do this easily, draw an x-axis which is big enough for the largest value in the data, and small enough for the smallest value in the data (in the entire collection of data). Plot each box-and-whisker diagram below each other.

More people in different professions are finding use for box and whiskers plots. It can be used very effectively in time series analysis, which may include engineers, economists, earth scientists, statistician, social sciences and medicine, to name a few professions. Stock market analysis using the open, hi, low & close format as used in Excel is not really the same, but it does show the range of the values for a stock, and relavent values. Excel (by Microsoft) does not have box and whisker plots, but there are many companies selling add in programs to make these plots. I use the Matlab program, which has the capabilities to make box and whisker plots. See related links.
It's eaiser to see the outlier ( odd number) out of the data.

They are never used there is no point in learning about them. We have to because it is required in school. So learn it but you will never use it.
Box-and-whisker plots highlight central values in a set of data. In order to construct a box-and-whisker plot, the first step is to order your data numerically and find the median value.
