Question

In the analysis phase, what methods can be used to avoid, minimize or control for confounding?

Answer 1

In the analysis phase of a study, methods such as random assignment, control groups, and placebos can be used to avoid, minimize, or control for confounding.

Step-by-step explanation:

In the analysis phase of a study, there are several methods that can be used to avoid, minimize, or control for confounding. These methods include:

1. Random assignment: By randomly assigning participants to different treatment groups, the researcher can minimize the influence of confounding variables. This ensures that any differences observed between groups are due to the planned treatments and not other factors.
2. Control group: Including a control group that does not receive the treatment helps to isolate the effects of the treatment. By comparing the response of the control group to the treated groups, the researcher can determine the true effect of the treatment.
3. Placebo: In some studies, it is possible to use a placebo treatment that looks identical to the active treatment but does not have any actual effects. This helps to blind both the researcher and the participants, reducing the potential for bias.
