Question

d a study of gender bias. The Who is the Better L The Pew Research Center c study was conducted as given below. In the experiment, two separate random samples of more than 1000 registered voters were asked to read a profile sent to them online of a hypothetical candidate for U.S. Congress in their district. One random sample of 1161 respondents read a profile of Ann Clark, described as a lawyer, a churchgoer, a member of the local Chamber of Commerce, an environmentalist and a member of the same party as the survey respondent. They were then asked what they liked and didn't like about her, whether they considered her qualified and whether they were inclined to vote for her. There was no indication that this was a survey about gender or gender bias. A second random sample of 1139 registered voters was asked to read a profile of Andrew Clark, who-except for his gender-was identical in every way to Ann Clark. These respondents were then asked the same questions. (a) What are the two treatments in this experiment? the two samples O the districts the two names given to the participants O participants' answers to the questions given the party (b) what are the response variables in this experiment? the two samples the districts the two names given to the participants

Explanation / Answer

Since the districts, party, questions asked to the respondents are same for both the samples, they are neither treatments nor the response variable.

The treatments in the experiment are the two names given to the participants.

The response variable in this experiment is the participants answers to the questions given.

Taking two separate random samples has the same benefit as the random assignment to the two treatments in this experiment because this is same thing as choosing 2300 voters and randomly assigning 1161 to the female name and the rest to the male name.
