What is the difference between stem and leaf and how do you find the range
Stem and leaf plots and finding the range are both ways to organize and analyze data.
A stem and leaf plot is a way to display numerical data in a visual format. In a stem and leaf plot, the stem represents the first digit or digits of each data point, while the leaf represents the last digit of each data point. For example, in the data set {23, 25, 28, 32, 35, 38, 42, 45}, the stem and leaf plot would look like:
2 | 3 5 8
3 | 2 5 8
4 | 2 5
Finding the range of a set of data involves determining the difference between the highest and lowest values in the data set. To find the range when presented with a stem and leaf plot, you would simply need to look at the extremes of the plot - the lowest and highest values listed. For example, in the stem and leaf plot above, the lowest value is 23 and the highest value is 45, so the range would be 45 - 23 = 22.
