Box-and-Whisker Plots A box-and-whisker plot shows the spread of a data set. It displays 5 key points: the minimum and maximum values, the median, and the first and third quartiles. Box-and-Whisker Plots The quartiles are the medians of the lower and upper halves of the data set....
Measurement and Data Leveled Problems: Stem-and-Leaf PlotsCollins, Anne M
Central tendency worksheets have practice pages to determine the mean, median, mode, range, and quartiles of the data. Word problems have been included.
You can also visualize the data using a stem and leaf plot to figure out the range in which most of your values lie. How to calculate range and midrange The range is the simplest measure of spread (how varied a set of numbers is). To find the range, calculate the difference between ...
