Answer 1

Selection type of bias can be introduced from the way in which cases and controls are chosen for a study.

First is what is actually the bias? The bias we can say is a type of error which usually occurs in the design as well as in the study of the particular process due to which it results in incorrect estimation with the association of the process.
