Each student is paired with another student who has similar characteristics, helping to eliminate potential confounding variables and providing a fair comparison between the online and in-person SAT preparation methods.
To eliminate potential confounding variables and providing a fair comparison between the online and in-person SAT preparation methods.
1. Identify the 30 students who have already taken the SAT once and are willing to participate in the experiment.
2. Pair the students based on relevant factors that may influence SAT score improvement, such as their initial SAT scores, GPA, or academic strengths.
3. Randomly assign one student from each pair to the online SAT preparation program group, and the other student to the in-person SAT preparation class group.
4. Ensure that both groups receive the same amount of preparation time and resources, keeping the experiment fair and unbiased.
5. Administer the SAT exam to all participants after they have completed their respective preparation programs.
6. Calculate the improvement in SAT scores for each student by subtracting their initial SAT score from their post-preparation SAT score.
7. Analyze and compare the average improvement in SAT scores between the online program group and the in-person class group using statistical methods.
8. Draw conclusions based on the findings, considering factors such as the mean improvement, variability, and statistical significance between the two groups.
By using a matched pairs design, the counsellor ensures that each student is paired with another student who has similar characteristics, helping to eliminate potential confounding variables and providing a fair comparison between the online and in-person SAT preparation methods.
