14. 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 present data in a clear and meaningful way using tables, bar graphs, histograms, and frequency distributions. These methods help in understanding large amounts of information easily.

 

The chapter also explains important statistical measures such as mean, median, and mode, which help describe the central tendency of data. Students also learn about cumulative frequency and ogive curves to analyze grouped data. Understanding statistics is very useful in real life for interpreting data in areas such as education, business, economics, research, and social studies.
