This award-winning series helps students to build confidence in their ability to "do math" and develop the knowledge and skills required to become mathematically literate. In this lesson we introduce the graphing calculator which has made possible the study of statistics earlier in a student's academic career. Statistics allows the student to see the usefulness of mathematics. Here, statistics is introduced using sets of data. The data is analyzed to measure tendency and variation. The concept of outlier is introduced. The box plot, a graphic display of data, is used to compare sets of data. Qualitative analysis of data is discussed. Students will learn to find the mean and median of a set of numbers and why the median is a better measure of tendency when the data contain extreme values.
