Chapter 12: Measures of Central Tendencies

What you need to learn in this chapter

In this chapter, we will be learning about measures of central tendencies. This means we will be finding the mode, mean, and median of a set of data. The mode is the value that appears most frequently, the mean is the average of all the values, and the median is the middle value when the data is arranged in order. We will also learn how changes in the data can affect the mode, mean, and median. By the end of this chapter, we will be able to analyze data and draw conclusions based on these measures.
