WebBias is a statistical term which means a systematic deviation from the actual value. It is a sampling procedure that may show some serious problems for the researcher as a mere increase cannot reduce it in sample size. Bias is the difference between the expected value and the real value of the parameter. In this article, we are going to discuss ... Web7. Bias means that the expected value of the estimator is not equal to the population parameter. Intuitively in a regression analysis, this would mean that the estimate of one of the parameters is too high or too low. However, ordinary least squares regression estimates are BLUE, which stands for best linear unbiased estimators.
