PISA - Program for International Student Assessment Interpreting PISA Data Results Questions and Answers

Question 1

An analyst observes that Country A has a mean mathematics score of 510 and Country B has a mean score of 500.
To determine if Country A's performance is genuinely higher, what is the most critical piece of information the analyst must consider?

Accepted Answer

The standard error of the mean for each country.

Answer

The raw scores of the highest-performing students in each country.

Answer

The number of students who participated in the assessment from each country.

Answer

The OECD average score for that assessment cycle.

Question 2

A PISA report shows that the performance gap in reading between students in the top and bottom quarters of the PISA index of economic, social, and cultural status (ESCS) is 95 points in Country X. Which of the following is the most accurate interpretation of this finding?

Accepted Answer

Socio-economic background is strongly associated with student performance in Country X.

Answer

Students from wealthy families in Country X are guaranteed to have high reading scores.

Answer

Educational resources are the only factor influencing reading scores in Country X.

Answer

Country X has a larger reading performance gap than all other participating countries.

Question 3

When analyzing PISA data, it is crucial to use student weights (W_FSTUWT). Which of the following is the primary reason for applying these weights?

Accepted Answer

To ensure the sample accurately represents the entire 15-year-old student population of a country.

Answer

To give higher-performing students more influence on the country's mean score.

Answer

To adjust for the different difficulty levels of the test questions.

Answer

To standardize the scores so that the OECD average is always 500.

Question 4

Country Y's mean science score was 490 in PISA 2018 and 505 in PISA 2022. Country Z's mean science score was 510 in 2018 and 515 in 2022. Based only on this information, which conclusion is invalid without further statistical analysis?

Accepted Answer

Country Y showed more significant improvement than Country Z.

Answer

Country Z performed better than Country Y in both cycles.

Answer

Country Y's score increased by 15 points.

Answer

Both countries saw an increase in their mean science scores.

Question 5

An analyst notes that Country C has a smaller standard deviation in its mathematics scores compared to most other countries, even though its mean score is near the OECD average. What does this smaller standard deviation most likely indicate?

Accepted Answer

A more equitable distribution of mathematics performance among its students.

Answer

A less challenging mathematics curriculum.

Answer

That its top-performing students are not as strong as in other countries.

Answer

A sampling error occurred during the data collection process.

Question 6

Which of the following describes a PISA proficiency level?

Accepted Answer

A description of the specific knowledge and skills students at a certain score range can typically demonstrate.

Answer

A percentile rank showing a student's performance relative to all other students globally.

Answer

A raw score based on the total number of questions a student answered correctly.

Answer

A grade equivalent, such as 'Grade 10 level', assigned based on the PISA score.
