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'.
