NCERT Solutions Class 9 Chapter 12 FAQs

What are the main topics in Class 9 Statistics?

Class 9 Statistics covers data collection, data presentation, graphical representation (bar graphs, histograms, frequency polygons), and measures of central tendency (mean, median, mode).

Why is Statistics important for Class 9 students?

Statistics helps students understand how to collect, organize, and interpret numerical data. These skills are useful in daily life and higher studies.

How do I calculate the mean of ungrouped data?

To calculate the mean of ungrouped data, sum all observations. Then divide this sum by the total number of observations.

What is the difference between a bar graph and a histogram?

A bar graph uses separate bars to compare different categories. A histogram uses adjacent bars to show frequency distribution for continuous data.

What are frequency distribution tables?

Frequency distribution tables organize raw data. They show how often each value or range of values appears in a dataset.
