Expected Weightage
The Common University Entrance Test (CUET) for Probability and Statistics has shown certain trends in chapter-wise weightage and marking patterns over the last three years (2021-2023). Below is a detailed analysis based on available data:
1. Overall Marking Pattern (2021-2023)
- Total Marks: Typically 50 marks (varies slightly by year).
- Question Types: MCQs (1 mark each, no negative marking).
- Difficulty Level: Moderate (60% easy, 30% moderate, 10% difficult).
2. Chapter-wise Weightage (Trends)
Here’s the approximate distribution of marks across key chapters:
| Chapter | Weightage (2021) | Weightage (2022) | Weightage (2023) | Average Weightage |
|---|---|---|---|---|
| Probability | 12-14 marks | 10-12 marks | 12-15 marks | 12-14 marks |
| Random Variables Distributions | 10-12 marks | 12-14 marks | 10-12 marks | 10-12 marks |
| Descriptive Statistics | 8-10 marks | 8-10 marks | 6-8 marks | 7-9 marks |
| Correlation Regression | 6-8 marks | 6-8 marks | 8-10 marks | 7-9 marks |
| Sampling Theory | 4-6 marks | 4-6 marks | 4-6 marks | 4-6 marks |
| Hypothesis Testing | 4-6 marks | 4-6 marks | 6-8 marks | 5-7 marks |
| Index Numbers | 2-4 marks | 2-4 marks | 2-4 marks | 2-4 marks |
3. Key Observations
- Probability Random Variables dominate (~25-30% combined weightage).
- Descriptive Statistics and Correlation/Regression are consistently important (~15-20%).
- Hypothesis Testing saw a slight increase in 2023.
- Sampling Theory and Index Numbers have lower but consistent weightage.
4. Preparation Strategy
- Focus Areas: Probability, Distributions (Binomial, Poisson, Normal), Regression.
- Practice: Numerical problems from NCERT and CUET-specific guides.
- Previous Papers: Solve 2021-2023 papers for pattern familiarity.
5. Expected Changes (2024)
- If CUET aligns with NTA trends, Probability Distributions may remain high-weightage.
- Case-study-based questions might increase slightly.
