I am trying to see how the appearance of the interviewer create response bias. My survey question is: "do you exercise on a weekly basis?"
I conducted a survey of 80 students using cluster sampling by choosing one room in each hallway, then four students in random from each. My control group of 40 students were asked by the interviewer in plain clothing, while the 40 left were asked while wearing sports attire.
The results of the survey are as follows:
a. Control Group: 65% said Yes (14 males and 12 females), 35% said No (3 males and 11 females)
b. Experimental Group 60% said Yes (18 males and 6 females), 40% said No (3 males and 13 females)
Since the interviewer in the experimental group was dressed in sports attire, we expected the students to be more compelled to say that they do exercise--but that is not that case. Am I missing something here? Or should I just conclude that wearing sports attire did not adversely affect student responses? In fact, there were 5% less people who said yes in the experimental group--would that small a number be just attributed to chance variation?
