Is kitab ke baare mein
The PCTB Statistics textbook for Class 11 (English Medium) takes students from raw data to probability theory in 9 chapters: Introduction to Statistics, Representation of Data, Measures of Location, Measures of Dispersion, Index Numbers, Probability, Random Variables, Probability Distributions, and the Binomial and Hypergeometric Probability Distributions — with a full answers section at the back.
The book's design is relentlessly practical: Chapter 2 teaches tables, graphs and charts for real data; Chapters 3–4 build the central-tendency and dispersion toolkit (mean, median, mode, variance, standard deviation); Chapter 5 applies them to index numbers; and Chapters 6–9 develop probability from basic rules to named distributions. Every chapter is packed with solved examples and exercises, and the answers section (page 250) lets students verify their working.

Ustad ka mashwara
Measures of Location aur Dispersion (Ch 3-4) mein formulas ki list chart par likhwa dein — yeh do chapters aadhe paper ka wazan rakhte hain. Probability mein tree diagram banane ki aadat dalwayein; bacha diagram bana le to sawal aadha hal ho jata hai.
