To find the key is very simple
just take one numbers from there and teach your reader how to read that number
EX:
6/8= 68
Just pick a random number and show them how to read it

Every proper stem-and-leaf plot must have a key given next to the plot.
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.
Here is the marks that each student has got after an exam in the class ploted out in a stem and leaf plot. 1-0234 2-34 3-56 4-678 5-0 6-134 7-689 8-049 9-26 Now for the key... Key: 6-9 means 69 The key is based on entirely what numbers you have used in the stem and leaf plot. The key is just the meaning for what sort of digits you are trying to talk about. If we don't use keys. Then when we look at 2-3, we might think that it is 2.3 Anyway you can get the key by looking at what data you are doing and just take out one section of the data. Here is another example: Here is the amount of pocket money received by a group of children represented in a stem and leaf plot: 1-345 2-167 3-89 Key: 2-6=2.6 In other words the key is just like the legend on a map. Just by looking at the stem and leaf plot you should be able to find it. I don't know if this would help... But I hope you would find this useful!! Good luck in stem and leaf plots! it is an example of the numbers
If you have a stem and leaf plot like this 4/567 5/234 6/2 you can use any of the number rows to make a key. Key: 6/2=62
The plot area is the rectangular area formed by the axes. The chart area is bigger and includes the title, the axes labels and values and the key (in its default positions).
