Exam 9: The Fundamentals of Research Methodology

When the design of an experiment simulates real-life conditions, it is said to be high in

When secondary variance is allowed to occur in experimental research,

It is virtually impossible to manipulate such variables as age, sex, race or income.

The whole point of using one of the various experimental designs is to

An example of a manipulated independent variable would be

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 dependent variable was based on the riots.

When subjects change their behavior simply as a result of the experimenter paying attention to them, this is called

Questions below will be bases on the following study: A researcher wishes to test whether the drug, magnesium pemoline, has any influence on intelligence. Two groups of subjects are randomly selected from the population of Omega University students. Group A is given the magnesium pemoline and then tested on the Stanford-Binet IQ test. Group B is given a placebo and, then, also tested on the Stanford-Binet. Both groups are tested under identical environmental conditions. -The group which received the placebo 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 research technique used in this study is an example of

In a study on whether college graduates earn more money then non-college graduates, the research method is almost certainly

The two basic types of research are

Experimental methodology demands the use of a manipulated independent variable.

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. -The fact that the two groups were led by different persons created the possibility of incurring

Whenever the hypothesis of difference is tested, the research method must have been experimental.

In this study the independent variable was

When a significant difference is found between the scores of the experimental and control groups, there is no possibility that this result could have occurred on the basis of chance.

When the measurement scale provides information regarding greater than or less than, but not how much greater or less, it is in the form of
