1. Which of the following statements is true about analyzing panel data? (Choose all that apply) *

1 point

To run a first-differences model, data must be in long form

To run a fixed effects model, data must be in long form

To run an ANCOVA model, data must be in long form

A first-differences model is biased if you’ve done an RCT

A fixed effects model is biased if you’ve done an RCT

An ANCOVA model is biased if you’ve done an RCT

None of the above

Required

Reshape the data long so that there are two observations per student.

2. How many test score variables are in the reshaped data? *

1 point

Run a fixed effects model to estimate the impact of treatment on the change in Hindi test scores. Don’t forget to cluster standard errors by village.

3. What is the estimated treatment effect? Round to the nearest 0.01 *

1 point

4. What is the correct interpretation of the coefficient on the binary variable denoting the testing round? *

1 point

The average score at endline for the whole sample

The average score at endline in the treatment group

The average score at endline in the control group

The average change in scores from baseline to endline for the whole sample

The average change in scores from baseline to endline for the treatment group

The average change in scores from baseline to endline for the control group

None of the above

Now reshape the data wide and run the equivalent ANCOVA model to estimate the treatment effect on Hindi test scores.

5. Which of the following statements is true about the differences between the ANCOVA model vs the fixed effects model? (Choose all that apply) *

1 point

The estimated treatment effects are the same in the two models

The estimated treatment effect is larger in the FE model than in the ANCOVA model

The estimated treatment effect is larger in the ANCOVA model than in the FE model

The estimated standard errors on the treatment coefficients are the same in the two models

The estimated standard error on the treatment coefficient is larger in the ANCOVA model than in the FE model

The estimated standard error on the treatment coefficient is larger in the FE model than in the ANCOVA model
