Search for "NCERT Class 11 Statistics for Economics" (Free official PDF). While Roy is for B.Com/MBA, the NCERT book covers 60% of the same basics (Mean, Median, Mode, Correlation) with exceptional clarity and is 100% legal to download from the NCERT website.

In an era of Big Data, a deep critique of traditional texts like Roy’s must acknowledge the lack of integration with modern statistical software (R, Python, or even advanced Excel). While the book builds a strong foundation in manual calculation—a necessary skill for understanding the logic—it lacks guidance on executing these analyses in a digital, high-speed business environment.

The book begins with the basics: classification, tabulation, and diagrammatic representation of data. Roy emphasizes bar diagrams, pie charts, and histograms as they appear in business annual reports.

This is where the book becomes advanced. It introduces large sample tests (Z-test) and small sample tests without getting lost in deep statistical jargon. The Chi-square test of independence (e.g., "Is product preference independent of gender?") is explained with typical marketing research data.
