Chapter 8 : Measures of Dispersion of Ungrouped Data

What will you learn in this chapter

In this chapter, we will be learning about measures of dispersion for ungrouped data. Dispersion refers to how spread out or scattered the data is. We will learn about different measures of dispersion, such as range, mean deviation, and standard deviation. We will also learn how to compare and interpret the dispersion of two or more sets of data using stem-and-leaf plots and dot plots. By the end of this chapter, we will be able to draw conclusions based on the dispersion of the data.
