13. Statistics

Statistics is the branch of mathematics that deals with the collection, organization, analysis, and interpretation of data. In this chapter, students learn how to represent large amounts of data using frequency distribution tables, histograms, and cumulative frequency curves (ogives). These graphical methods make it easier to understand patterns and trends in data.

 

The chapter mainly focuses on finding the mean, median, and mode of grouped data, which are measures of central tendency. These concepts help summarize and analyze information in a meaningful way. Understanding statistics is very useful in real-life fields such as education, economics, research, business, and social sciences, where data analysis is essential for making decisions.
