What Self selection is
Self selection is a form of selection bias in which participants in a study choose whether or not to participate. This type of selection bias can lead to inaccurate results as only participants who have a particular interest in the study may choose to participate.
Steps for Self Selection:
- Define the criteria for eligibility: The researcher must decide who is eligible to participate in the study.
- Inform potential participants: Potential participants must be informed of the study’s purpose, requirements, and risks.
- Invite participants to participate: The researcher must actively seek out potential participants and invite them to participate in the study.
- Allow participants to choose: The researcher should allow potential participants to choose whether or not they want to participate in the study.
- Evaluate the results: The researcher must evaluate the results of the study to ensure that the data is not biased by self-selection.
Examples

-
In observational studies, self-selection occurs when individuals are free to choose whether or not they want to be included in the study.
-
In clinical trials, self-selection occurs when participants are allowed to decide for themselves whether or not to take part in the study.
