In: Statistics and Probability
Which of the following is a biased estimator? That is, which of the following does not target the population parameter?
Choose the correct answer below.
Mean, Proportion, Median, Variance
Answer:
Given Data
The answer is median because the mean of the sample median doesnot give an estimate of the population median.
But if this is a multiple correct mcq then you can also choose variance because the sample variance with divisor
n sample size) is a biased estimator of the population variance. Sample variance with divisor n-1 is unbised for population variance.
