Question
What is spurious correlation? Give some examples.
✓
Answer
When two variables reflect correlation statistically but logically we can't expect them to be correlated, it is called spurious correlation. Two examples are as follows:
- Where there were more doctors, death rates were high.
- When there was high rainfall, more students has A grades.
- Number of storks and birth rate in Denmark.
- Number of priests in America and alcoholism.
- In the start of the 20th century it was noted that there was a strong correlation between 'Number of radios' and 'Number of people in Insane Asylums'.
