Is a stem and leaf plot the same as a box and whiskers 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.
How do you work out key in stem and leaf diagram?
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
How do you get the key in a stem and leaf plot?
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

What is a modal group in stem and leaf diagrams?
If you had a stem and leaf diagram like this for example 1/1,2,6 2/4,4,4,5,7,8,9 3/1,6 4,2 5/4,7 Key 1/1- 11 years old The mode would be the value on the "leaf" that appears most frequently so in this case it would be 24. However, the modal group would be the group from the "stem" that has the most values, so in this case it would focus on the 20's. You would write it from the number on the stem to the highest in the group, like- 20-29. You would write it from 20 even if there is nobody who is actually 20 years old, as there isn't in this case.
