Question

Which of the following are methods to control for confounding? (Select all that apply)

a. Stratification

b. Randomization

c. Regression

d. Correlation

e. Matching

Answer 1

b. Randomization

e. Matching

Explanation:

By using randomization and matching methods, we would control the confounding in the research study. The matching is useful for controlling the complex and multifaceted variables and we use this method in most of the case-control studies. Also, we use randomization for controlling the confounding variables when large sample size is given for the research study. We can also use the restriction method for the controlling of the confounding variables.
