Question

Exit polls do not always predict correctly. Why? ​

Answer 1

Explanation:

The sorry state of exit polls is illustrated again and again in India where many of the popular exit poll results fail to predict the final result with reasonable accuracy. No wonder people tend to treat them as pure entertainment.

There is enough doubt on the techniques and sample sizes of many polling organisations. Even if the sampling is random and representative of the population, and the sample sizes are adequate, other kinds of errors exist, including ‘non-response biases’.
