Which of the following is true regarding bias and/or confounding?
A.Blinding is a method to control for the effects of confounding.
B.A strategy that will help to reduce selection bias is enrollment of all cases in a defined time and region.
C.Bias occurs when a separate risk factor is associated with both the outcome variable and one of the other predictor variables.
D.Confounding could be caused by a separate risk factor that is associated with both the outcome variable and one of the other predictor variables.
Homework Answers
Ans) C.Bias occurs when a separate risk factor is associated with both the outcome variable and one of the other predictor variables.
Explaination:
- Bias is any trend or deviation from the truth in data collection, data analysis, interpretation and publication which can cause false conclusions. Bias can occur either intentionally or unintentionally. Intention to introduce bias into someone’s research is immoral. Nevertheless, considering the possible consequences of a biased research, it is almost equally irresponsible to conduct and publish a biased research unintentionally

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...

1. Each of the following statements is descriptive of situations which may be likely to present one of the major types of bias or confounding. If bias or confounding is probable, select the type which is most likely to occur by writing ‘confounding’, ‘information bias’, ‘selection bias’, or ‘no bias’, and a brief justification (in one sentence) to support your choice. a).

1) True or False? When a new prevention measure for a disease is developed, both the incidence and prevalence of the disease will decrease over the long term. 2) In 2015, a diagnostic code for Asperger’s disease was added to the ICD-10 (a cookbook for medical disease). Prior to 2010, there was no code to assign for the condition and thus, clinicians were inaccurately diagnosing Asperger’s disease cases with “unspecified autism”. To individuals not aware of this coding scheme, it...
Which one of the following statements is true regarding the evolution of risk and risk management?...
Which one of the following statements is true regarding the evolution of risk and risk management? The definition of risk has evolved to include positive as well as negative attributes. Risk management now involves only those areas where the organization has some degree of control over the outcome. The definitions of risk and risk management have become considerably more focused over the years. Risk management is increasingly being applied to the risks associated with accidental losses.
