2. Which of the following statements is TRUE (1 mark)? a) Selection bias can be reduced by increasing sample size. b) Loss to follow-up in a cohort study can bias findings either towards the null (reducing the magnitude of the true association) or the opposite (over-estimating the magnitude of the true association). c) Systematic error can be reduced by taking repeated measurements. d) Non-differential misclassification of exposure or outcome usually biases study findings away from the null (towards finding an...
