Exam 2: Research Methodology

If a researcher believes that participants in a single group will score very differently from one another on a task, that researcher can find out if that is true by looking at the:

The fact that small samples are generally less reliable indicators of typical behaviour than large samples is associated with the principle of:

Something that can be measured or manipulated by an experimenter is considered:

The approach that would be LEAST useful in identifying how a specific region of the brain functions with a person engaged in a given task would be:

When a researcher joins a social group and talks to the members in order to study that group, the approach is referred to as:

The variable that a researcher measures in an experiment to see if it has changed after a treatment is called the:

According to some psychologists, Sigmund Freud's theory of the meaning of dreams was not a successful theory because:

Self-report questions on which the respondent can generate his or her own responses are called:

Bai is conducting a study on learning. When she manipulates an independent variable, it is possible that some other factor, like noise in the hall, can affect learning in one of the groups but not in the other. This possibility reflects the presence of:

When collecting data in a study, if researchers unconsciously code a person's behaviour to match their expectations, we say that there is:

Research has shown that some types of behavioural or psychiatric disorders show higher levels among people with low levels of education. This pattern of data is associated with:

When you pair two variables, and as one increases the other decreases, your data will show:

If a researcher publicly discussed a participant's responses and named the participant, that researcher would be guilty of violating what specific ethical principle?

A research team told one group of people that they would hear a set of jokes that were very funny and a second group that they would hear jokes that were not very funny. A third group was not told anything about the jokes. The jokes in all conditions were the same. Research with this design is:

The values in a data set range from 60 to 90. If a researcher knows this, then the researcher is aware of the:

Transcranial magnetic stimulation investigates the activity of a given region of the brain through the:

If a researcher defined happiness based on the number of times a person smiled in a 15-minute period, the number of smiles would be:

A researcher believes that presenting possible suspects in a lineup one at a time instead of in a group would lead to more accurate identification of the true suspect. This belief represents:

When people are aware of being observed, they might change their behaviours. This phenomenon illustrates:

When researchers report a measure of central tendency, they might present:
