Our Statistical Variability lesson plan goes over vocabulary and concepts such as variability, range, interquartile range, and outliers. It also spends time on how to interpret this data from various types of graphs. During this lesson, students are asked to complete a fun and interactive activity in which they craft a sculpture out of clay, weigh it, and record it along with the weights of everyone else’s sculptures; they are then asked to answer questions about the data and create a box and whiskers plot for it. Students are also asked to individually complete practice problems in order to demonstrate their understanding of the lesson.
At the end of the lesson, students will be able to recognize the difference between measures of center and variability. The students will also be able to calculate the measure of variability and compare side by side graphs.
