Optional Activity 3 – Correlation & Chi-Squared Tests

[Kspann]

1. What does the correlation coefficient suggest about the link between social anxiety and study hours?

The correlation coefficient is -0.90, which is a strong negative relationship. This means that as social anxiety increases, study hours decrease. Students with higher anxiety tend to study less.

2. Is the relationship statistically significant?

Yes. The p-value is 0.0003, which is well below 0.05. This relationship is statistically significant, meaning the link between social anxiety and study hours is unlikely due to chance.

3. Does attendance level predict whether a student passed?

Yes. The Pearson Chi-Square test was significant (p = .020). This means attendance level and passing outcome are not independent — they are related. So, yes, attendance level can help predict whether a student passed.

4. Which result would you prioritize when designing academic interventions?

Honestly, I would prioritize attendance for practical and effective interventions. While anxiety is strongly related to study habits, improving attendance is more manageable in a school setting. It is also statistically linked to passing, as seen in the results of the Chi-Square test.
