Exam 9: The Fundamentals of Research Methodology

The frequency of occurrence within mutually exclusive categories provides nominal data.

The issue of which scale of measurement has been used largely determines

The concept of "mutually exclusive" categories is central to

Questions below will be based on the following: A researcher wishes to test the hypothesis that intelligence is a sex-linked characteristic. A random sample of 1000 women is selected and given IQ tests. Similarly, a random sample of 1000 men is selected and also given IQ tests. The mean IQ's of the two groups are compared and the difference is found to be significantly in favor of the females. -This study proves that

In the following questions, you are to identify the alternative which is NOT appropriately grouped with the others

When it is established that a change in the independent variable actually produces a change in the dependent variable, then the research must be

The main purpose of post-facto research is to establish equivalent groups subjects.

When an independent variable is actively manipulated, the research must be post-facto.

In studies of prison riots, it has been found that prison riots increase as security measures are heightened (Useem & Kimball,1989). In these studies the independent variable is the heightened security.

In the classic Kansas City preventive control study (1973) it was found that applying different police patrol strategies had absolutely no impact on crime rates. The dependent variable in this study was based on the crime rates.

In experimental research on humans, the dependent variable is

In the classic Kansas City preventive control study (1973) it was found that applying different police patrol strategies had absolutely no impact on crime rates. The independent variable in this study was based on the crime rates.

When a person is viewed as being positive in one area, and then is assumed to be positive in other areas, this is called

Questions below will be based on the following: A researcher wishes to test the hypothesis that intelligence is a sex-linked characteristic. A random sample of 1000 women is selected and given IQ tests. Similarly, a random sample of 1000 men is selected and also given IQ tests. The mean IQ's of the two groups are compared and the difference is found to be significantly in favor of the females. -The results of this study suggest that

Comparing the experimental method with the quasi-experimental method

Post-facto research techniques may only be used to test the hypothesis of difference.

Whenever the independent variable had been assigned, the research must be post-facto.

Questions below will be based on the following: A researcher was interested in discovering whether attitude changes can be more effectively brought about when persons are made to feel part of the decision making process. A group of women was selected and randomly assigned to one of two groups, one group being placed in a large lecture hall, and the other in a small discussion-group setting. In the lecture setting, a speaker exhorted the women to use less expensive cuts of meat, whereas in the small-group setting a different group leader, although raising the same issues as the lecture had, also encouraged the subjects to participate in the discussion and offer suggestions, Several weeks later both groups of women were checked at home to determine whether they were indeed using the meat cuts which had been urged. Only 3% of the lecture group members had the meat cuts, whereas 32% of the discussion group members had the meat cuts. The difference was clearly significant. -Whether or not the women later had the meat cuts defined

In the following questions, you are to identify the alternative which is NOT appropriately grouped with the others

In any antecedent-consequent relationship, the independent variable
