By transferring the numerical data from the cumulative frequency curve into a box and whiskers plot.
They are some measure of the dispersion or range of numbers in the set of data.

No, they are two different things. Mainly because the Box And Whisker Plot has a different technique and focuses on highs and lows. The Stem and Leaf Plot has to do with key codes, grouping numbers, and amounts.
The box goes from the lower quartile to the upper quartile and has the median marked across it. The whiskers stretch out, from the box, to the minimum and the maximum.

The highest and lowest numbers in a box and whisker plot are shown by the two dots at the end of the "whiskers". To find the range, you must subtract the highest number from the lowest number.
The whiskers mark the ends of the range of figures - they are the furthest outliers. * * * * * No. Outliers are not part of a box and whiskers plot. The whiskers mark the ends of the minimum and maximum observations EXCLUDING outliers. Outliers, if any, are marked with an X.

The minimum - or outlier-adjusted minimum.
A box plot may be used at a preliminary stage to determine the centre and spread of a set of data. The box [and whiskers] plot measures the central point by the median and the range from the maximum and minimum or the quartile points.
Probably the box and whiskers plot, but there are others.
If the data are quantitative they must have a median. If there is no median it is only because the data are qualitative and, in that case, a box and whiskers plot is meaningless.
