🗓️ Section-wise Topic Map​

Section A Topics (10 marks — computation or long conceptual)​

These topics dominate Section A. Expect 1 computation + 1 conceptual every paper:

Computation (Section A):

  • One-Way ANOVA (virtually every paper)
  • Spearman's Rho (2 of every 3 papers)
  • Regression equation (2 of every 3 papers)
  • Pearson's r (mostly older papers, occasionally post-2015)
  • t-Test (occasional)

Conceptual (Section A):

  • Parametric vs Non-parametric (every single paper)
  • Normal Probability Curve (very frequent)
  • Hypothesis Testing (very frequent)
  • Divergence from Normality (frequent)
  • Descriptive Statistics / Data Organisation (moderate)

Section B Topics (6 marks — medium computation or conceptual)​

  • Computation: Mann-Whitney U (nearly every paper), Chi-square (most papers), Kendall's Tau (frequent)
  • Conceptual: Two-way ANOVA/interactional effect, Levels of measurement, Standard error, Point biserial & phi, Partial correlation, Kruskal-Wallis, Biserial & tetrachoric

Section C Topics (3 marks — short notes)​

Rotating short notes (write 4–5 key points):

  • Type I and Type II errors (very frequent)
  • Level of significance (frequent)
  • Degrees of freedom (occasional)
  • Kurtosis / Skewness (frequent)
  • Standard error (occasional)
  • Partial correlation (occasional)
  • Wilcoxon test (occasional)
  • Histogram / scatter plot (occasional)

💡 Exam Insights​

Guaranteed Questions (Appear Every Year)​

  1. Parametric vs Non-parametric — in some form, every single paper
  2. One-Way ANOVA computation — almost every Section A
  3. Chi-square computation — almost every paper (Section A or B)
  4. Normal Probability Curve — properties or applications, every year

Safe Section A Strategy​

  • Always be ready to answer: Parametric/Non-parametric (conceptual) + ANOVA (computation)
  • Backup conceptual: Normal curve, Hypothesis testing, Divergence from normality
  • Backup computation: Spearman's Rho, Regression equation

Safe Section B Strategy​

  • Mann-Whitney U computation (nearly certain)
  • Two-way ANOVA / interactional effect (reliable)
  • Levels of measurement (reliable)
  • 4th choice: Kruskal-Wallis, Standard error, or Point biserial

Safest Section C Short Notes​

  1. Type I and Type II errors
  2. Level of significance
  3. Kurtosis (or skewness)
  4. Degrees of freedom
