Question

71. A researcher wants to know whether writing an essay on a controversial topic will have an effect on the attitudes held by people. First, she administers an attitude survey that covers a number of topics, including electronic voting machines. She then randomly assigns subjects to write an essay either supporting or opposing the use of electronic voting machines. One week later, she administers the same attitude survey and compares those responses to the responses from the first time the survey was administered. In this experiment, the dependent variable (DV) is A) electronic voting machines B) the researcher's attitudes C) the essay D) the controversial topic E) the attitude survey 72. In experimental research, one variable is systematically changed. This variable is known as the A) confound B) dependent variable C) independent variable D) experimental group E) control variable 73. The procedure that ensures that participants are not assigned to an experimental condition on the basis of any individual characteristics is called A) informed consent B) generic subjectification C) random assignment D) confound control E) interaction 74. There are two important ethical issues involved in the use of deception in research These issues include the possibility of harming research participants by the deception and A) participants become too trustful of researchers in the future B) the research may be flawed because deception leads participants to react unnaturally in research settings C) participants may learn that deception is acceptable and appropriate behavior in other situations and settings D) participants may resent being deceived researchers maycome to vie w dece pthon as Consent

Answer 1

71. e)The attitude survey

Explanation: In a study looking at how essay impacts views, the dependent variable would be the participants' attitude, since that is what is being measured.

72. c)Independent Variable

Explanation: An independent variable means to change its level systematically so that different groups of participants are exposed to different levels of that variable, or the same group of participants is exposed to different levels at different times.

73. c)Random Assignment

Random Assignment ensures that each participant or subject has an equal chance of being placed in any group. Random assignment of participants helps to ensure that any differences between and within the groups are not systematic at the outset of the experiment.

74. e)Researchers may come to view deception as a rasonable and necessary approach to obtaining informal consent.
