What is the difference between biased and unbiased in literature?
An unbiased estimator is an accurate statistic that’s used to approximate a population parameter. “Accurate” in this sense means that it’s neither an overestimate nor an underestimate. If an overestimate or underestimate does happen, the mean of the difference is called a “bias.”Mar 23, 2015.

What is the meaning of biased and unbiased coin in probability?
In unbiased coin both the sides have the same probability of showing up i.e, 1/2 =0.50 or 50% probability exactly when experimented with both sides alternately facing up before tossing the coin in air under identical conditions. In a biased coin probabilities are unequal.
How do you determine an unbiased estimator?
Unbiased Estimator Draw one random sample; compute the value of S based on that sample. Draw another random sample of the same size, independently of the first one; compute the value of S based on this sample. Repeat the step above as many times as you can. You will now have lots of observed values of S.
Why is it important to have an unbiased sample?

What is the difference between biased and unbiased estimators?
The bias of an estimator is concerned with the accuracy of the estimate. An unbiased estimate means that the estimator is equal to the true value within the population (x̄=µ or p̂=p). Within a sampling distribution the bias is determined by the center of the sampling distribution.

What is meant by unbiased error?
Unbiased errors are those errors that arise not because of the personal judgement but because of the problem in determining samples i.e. difference between the items that are included for the sampling purpose and items that are not included.
