Sample interview questions: What steps do you take to minimize selection bias in your research studies?
Sample answer:
- Define the target population clearly. This involves specifying the inclusion and exclusion criteria for participation in the study. By carefully defining the target population, researchers can reduce the risk of selection bias by ensuring that the sample is representative of the population of interest.
- Use random sampling methods. Random sampling methods, such as simple random sampling, systematic random sampling, or stratified random sampling, give each member of the target population an equal chance of being selected for participation in the study. This helps to reduce the risk of selection bias by minimizing the influence of researcher discretion or other factors that could lead to bias.
- Control for confounding variables. Confounding variables are variables that are associated with both the exposure and the outcome of interest. If confounding variables are not controlled for, they can lead to biased results. There are a number of methods for controlling for conf… Read full answer
