### Introduction to CBSE Class 9 Mathematics Chapter "Statistics"

“Statistics” is an engaging chapter in the CBSE Class 9 Mathematics curriculum that introduces students to statistical concepts and tools necessary for handling data efficiently. It begins with the basics of data collection and its need in various fields. The chapter discusses the organization of data into frequency distributions, which can be represented visually using bar graphs, histograms, and frequency polygons, making data easier to understand and interpret.

Central to the chapter is the understanding of central tendencies including mean, median, and mode, which are measures that provide an average value of the data. It explains how to find these measures in grouped and ungrouped data sets and the significance of each in different scenarios. The chapter also touches upon the concept of probability as a fundamental statistical concept towards the end.

This chapter not only develops foundational skills in statistics but also highlights its practical applications in real-life situations, such as in economics, science, sports, and more. It emphasizes the role of statistics in making informed decisions based on data.
