I can’t provide or link to pirated copies of books. I can, however, help with lawful alternatives and useful text-based material:

  • Summary: A concise overview of the typical contents of "Statistical Methods" by S. C. Gupta / S. P. Gupta or similarly titled textbooks (since "Ng Das" might refer to a different author—please confirm if you meant "G. N. Das" or another author). Typical chapters: descriptive statistics, probability, sampling distributions, estimation, hypothesis testing, regression and correlation, ANOVA, nonparametric tests, categorical data analysis, and multivariate methods.

  • Key formulas and concepts (compact reference):

    • Measures of central tendency: mean, median, mode.
    • Dispersion: variance, standard deviation, IQR.
    • Probability rules: P(A∪B)=P(A)+P(B)−P(A∩B); conditional probability P(A|B)=P(A∩B)/P(B).
    • Bayes’ theorem.
    • Discrete distributions: Binomial (mean=np, var=np(1−p)), Poisson (mean=λ, var=λ).
    • Continuous distributions: Normal N(μ,σ²), standardization z=(x−μ)/σ.
    • Sampling distribution of the mean: for large n, x̄ ~ approx N(μ, σ²/n).
    • Central Limit Theorem.
    • Confidence interval for mean (σ known): x̄ ± z*(σ/√n). (σ unknown: use t-distribution)
    • Hypothesis testing: test statistic, p-value, type I/II errors, power.
    • Two-sample tests: pooled/unpooled t-test formulas.
    • Linear regression: y = β0 + β1 x + ε; β1̂ = Cov(x,y)/Var(x); SSE, SSR, SST, R².
    • ANOVA: F = MSbetween / MSwithin.
    • Chi-square test for independence: χ² = Σ (O−E)²/E.
    • Nonparametric: Wilcoxon, Mann–Whitney U, Kruskal–Wallis brief uses.

  • Short worked example — two-sample t-test (assume unequal variances):

    1. Data: sample means x̄1, x̄2; sample variances s1², s2²; sizes n1, n2.
    2. Test statistic: t = (x̄1 − x̄2) / sqrt( s1²/n1 + s2²/n2 ).
    3. Degrees of freedom (Welch’s approx): ν ≈ (s1²/n1 + s2²/n2)² / [ (s1^4)/(n1^2 (n1−1)) + (s2^4)/(n2^2 (n2−1)) ].
    4. Compare |t| to t_ν,α/2 or compute p-value.

  • How I can help next (pick one):

    1. Generate a detailed chapter-by-chapter summary for a standard "Statistical Methods" text.
    2. Produce printable formula sheets (1–2 pages) for exams.
    3. Create worked examples and step-by-step solutions for specific topics (e.g., ANOVA, regression).
    4. Point to legal sources: open textbooks, library copies, or publisher pages (I can search for those).

Tell me which option you want (or confirm the exact author/title) and I’ll prepare it.

📚 Review of Statistical Methods by N.G. Das

Target Audience: Undergraduate and postgraduate students of statistics, economics, commerce, and social sciences, especially in Indian universities.

Content Overview:

  • Descriptive statistics (measures of central tendency, dispersion, skewness)
  • Probability theory basics
  • Random variables and probability distributions
  • Sampling theory and estimation
  • Hypothesis testing (z, t, F, chi-square tests)
  • Correlation and regression analysis
  • Non-parametric tests
  • Analysis of variance (ANOVA) – introduced, but not exhaustive
  • Index numbers and time series

Strengths: ✅ Clear and simple language – beginner-friendly
✅ Many solved examples and practice problems
✅ Step-by-step mathematical derivations
✅ Wide coverage of traditional statistical techniques
✅ Good for exam preparation (B.Com, B.Sc, M.A. Economics)

Weaknesses: ❌ No coverage of modern computational statistics (no R, Python, SPSS examples)
❌ Very limited explanation of statistical software or data visualization
❌ Some sections feel outdated compared to newer textbooks (e.g., Gujarati, Gupta)
❌ Not suitable for advanced/mathematical statisticians – lacks rigorous proofs
❌ Minimal real-world case studies

Verdict:
⭐ 3.5/5 – A solid, no-frills textbook for university exams in social sciences and commerce. However, for data science, research methodology with software, or advanced statistics, consider Statistics for Business and Economics by Anderson or Introductory Statistics by Wonnacott & Wonnacott.

Better legal alternatives (many with free legal previews):

  • Fundamentals of Mathematical Statistics – S.C. Gupta & V.K. Kapoor
  • Statistical Methods – S.P. Gupta
  • Introduction to the Practice of Statistics – Moore, McCabe (free chapters online)
