Correlation and Causation
Research Aptitude
Useful for: OSSC Art Education Instructor, OSSC Economics, OSSC English, OSSC Foundation Course, OSSC Geography, OSSC History, OSSC Mathematics, OSSC Odia
Overview
Correlation shows that two variables move together; causation means one variable produces change in the other — correlation alone does not prove causation.
Key points
- Correlation coefficients range from −1 (perfect negative) to +1 (perfect positive); 0 means no linear relationship.
- A third (confounding) variable may cause both.
- Reverse causation: the effect may actually be the cause.
- Spurious correlations occur by coincidence.
- Randomised experiments are the strongest way to show causation.
- Correlation is useful for prediction even without causation.
Explanation
- Scatter plots show the form of a relationship.
- Strong correlation is not the same as large effect.
- Longitudinal data help establish time order.
- Controlling variables reduces confounding.
- Be cautious with headlines claiming causes from surveys.
Step by step
- Identify the concept, method or policy asked.
- Recall the definition, thinker, year or rule.
- Apply it to the situation and eliminate extreme options.
Examples
- Ice-cream sales and drowning both rise in summer → confounding by temperature.
- Students who read more score higher → correlation; an experiment is needed to show reading causes the gain.
- r = −0.8 between absence and marks → strong negative correlation.
Traps and advanced points
- Trap: Inferring causation from correlation.
- Trap: Thinking r = 0 means no relationship of any kind.
- Trap: Ignoring confounders.
Quick revision
- −1 to +1.
- Confounding, reverse causation.
- Experiments for causation.
Practice MCQs
Choose the most defensible exam-ready conclusion about Correlation and Causation.
- A strong correlation always proves that X causes Y.
- Correlation and Causation is useful only for record keeping and has no effect on learning.
- Correlation and Causation should be applied identically in every situation without checking learner needs.
- Correlation alone does not establish causation because confounding, directionality and chance may explain an association.

Answer: (d) Correlation alone does not establish causation because confounding, directionality and chance may explain an association.. Choose the most defensible exam-ready conclusion about Correlation and Causation.: Correlation alone does not establish causation because confounding, directionality and chance may explain an association.
For scientific work involving Correlation and Causation, which practice would most improve quality?
- Use controlled designs, temporal order and converging evidence before making a causal claim.
- If two trends rise together, confounding variables cannot matter.
- Causal direction can always be inferred from a scatter plot alone.
- Correlation shows that variables vary together; causation requires stronger evidence that alternative explanations and confounding factors have been addressed.
