(h)
i. Define response bias and provide an example.
ii. Define selection bias and provide an example.​

Answer 1

Answer:

1)Extreme responding is a form of response bias that drives respondents to only select the most extreme options or answers available. For example, in a survey utilizing a Likert scale with potential responses ranging from one to five, the respondent may only give answers as ones or fives

2)It gives biased results where it is unequal in regard to exposure and/or outcome. For example, in a test of a dieting program, the researcher may simply reject everyone who drops out of the trial, but most of those who drop out are those for whom it was not working
