. What is meant by differential misclassification bias? Generally speaking, how does this bias the results (i.e., in what direction)? 8. What is meant by non-differential misclassification bias, and how does this bias the results (i.e., in what direction) ? 9. a) Assume that the true and estimate relative risks are greater than 1. If the true relative risk is greater than the estimated relative risk, what direction is the bias (i.e., toward or away from the null?). You should use an example with actual numbers (fictional is fine) to clarify your answer. b) Assume that the true and estimated relative risks are less than 1 and the true relative risk is greater than the estimate risk – what direction is the bias (i.e., toward or away from the null?).
