Exam 2: Research Methodology

Which of the following is likely to be associated with observer bias?

If a researcher's data are reliable:

If a researcher wants to be able to generalize about a population using data pulled from a sample, it is best to use:

A psychologist wants to create two groups that are as similar as possible at the beginning of an experiment. To do this, she should use:

Investigators who are interested in gaining a lot of information about group attitudes quickly are likely to use what kind of research approach?

Anam is studying the intelligence of a group of people as they progress through early adulthood to old age. Her approach should involve:

Wilhelm randomly assigns participants to two groups and compares the group that receives a treatment with the group that receives no treatment. The group that gets the treatment is the:

When identifying the pool of participants who will be in a research project, psychologists generally use:

Psychologists have greater confidence in research results when:

If a participant always shows fast reaction times on a visual task not because she is good at the task but because she can hear the experimenter start the presentation and can get ready for the stimulus, her data will show a high level of:

The matter of who has access to data collected in an experiment is associated with what ethical issue?

One issue that a research ethics board is likely to concern itself with is:

When data collected in research are not useful in addressing the issue that the investigator is studying, we say that the data are not:

Using correlational studies, psychologists have studied whether exposure to violence in the media leads to violent behaviour. They have found that participants who have been exposed to more violence in the media are, in general, more violent. It is not clear from such research which one causes the other. The problem in interpreting these results involves:

Suppose a researcher intended to study people's level of happiness by monitoring how often they smile or laugh when watching a movie. If this measurement does not really indicate level of happiness, psychologists would say that the data are not:

In observational studies, participants sometimes show reactivity. A related phenomenon in self-report studies is called:

When researchers study multiple groups and report means of each group, they are reporting:

Samir is conducting a correlational study, and he cannot determine whether one variable causes another. One reason is that the additional variables that he did not study could influence the variables he did study. This reflects the problem with:

The variable that a researcher manipulates in an experiment is called the:

A researcher is interested in understanding how people like Kimveer Gill (the man who shot 19 people at Dawson College in Quebec) could commit murderous outbursts. In order to study these extremely rare individuals, a psychologist would most likely conduct:
