Statistics:

1. Hypothesis Testing:
   Explain the steps involved in hypothesis testing. What is the difference between a Type I error and a Type II error?

2. P-value Interpretation:
   What is a p-value in the context of hypothesis testing? How do you interpret it in deciding whether to reject the null hypothesis?

3. Confidence Intervals:
   Define a confidence interval. How does the choice of confidence level (e.g., 95% vs. 99%) affect the interval?

4. Linear Regression:
   What is the purpose of linear regression analysis? Explain the method of least squares and its role in determining the best-fit line.

5. ANOVA (Analysis of Variance):
   What is ANOVA used for? How does it help in comparing more than two group means?

6. Correlation vs. Causation:
   Differentiate between correlation and causation. Why is it important not to confuse the two in statistical analysis?

7. Standard Deviation and Variance:
   How are standard deviation and variance related? Why is standard deviation more often used in practice than variance?

8. Sampling Techniques:
   Explain the difference between stratified sampling and cluster sampling. When is each method preferable?

9. Bias and Variance Trade-off:
   What is the bias-variance trade-off in the context of model performance? How does it affect the generalization of a statistical model?

10. Chi-square Test:
    What is the chi-square test used for? Provide a scenario where a chi-square test might be appropriate for hypothesis testing.
