Chapter 7: Measures of Dispersion of Grouped Data
What you need to learn in this chapter
In this chapter, we will be learning about measures of dispersion for grouped data. Dispersion refers to how spread out the data is. We will learn how to construct a histogram and frequency polygon for a set of grouped data. These graphs will help us visualize the data and understand its dispersion. We will also learn how to compare and interpret the dispersions of two or more sets of grouped data using the histogram and frequency polygon. This will allow us to make conclusions about the data sets.
