Every proper stem-and-leaf plot must have a key given next to the plot.
how do i make a stem and leaf plot with decimals
a leaf is part of 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.
The range is the difference between the maximum score and the minimum score. Let's look at an example. [Figure2] The smallest number in the stem-and-leaf plot is 22. You can see that by looking at the first stem and the first leaf. The greatest number is the last stem and the last leaf on the chart. In this case, the largest number is 55. To find the range, subtract the smallest number from the largest number. This difference will give you the range. 55 - 22 = 33 The range is 33 for this set of data.
