Solution:
Bias in a sampling method means that the sample results will systematically misrepresent the population in the same way when one takes repeated samples.
Bias in sampling means when a sample statistic is not able to correctly represent the true value of of the population characteristics. For example, a bias will occur if the average salary for the sample observations does not accurately reflect the true average salary of the members of the population.
Therefore, bias in the sampling method means the sample results will systematically misrepresent the population in the same way when one takes repeated samples.
