Explain the difference between a biased and an unbiased statistic.

To determine

**To Explain:** The difference between a biased and an unbiased statistic.

Explanation

When the average value of the statistic is equal to the population parameter then that sample statistic is known as unbiased estimator. Similarly, when the average value of the statistic is not equal to the population parameter then that sample statistic is known as biased estimator. For instance, unbiased estimator mathematically shown as:

Similarly, biased estimator is shown as:
