How do you find the modal group in a back to back stem and leaf diagram?
To find the modal group in a back-to-back stem-and-leaf diagram, you need to look for the group with the highest frequency on both sides of the diagram. This group represents the mode for the data set. The mode is the value that appears most frequently in the data. In a back-to-back stem-and-leaf diagram, the modal group will be the one with the highest frequency on both sides of the stem.

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.
How do find the average on a stem and leaf plot?
You would take all the numbers from the data and then divide by the number of numbers added. In a stem and leaf plot, the tens or hundreds, and so on are on the left and the ones are on the right.
