Exam 2: Research Methodology

If a researcher wanted to study the behavior of protesters who were in a closed group and did not easily admit new people,the researcher would probably use which of the following approaches to study them?

It would NOT be possible for a researcher to study creativity in an experiment if the researcher:

Socially desirable responding is a potential problem in research because it may:

Why do scientists and researchers use statistical methods to determine whether their results are statistically significant?

The mean,median,and mode are all examples of:

Dr.Smith reads about a research study investigating whether a reading intervention has a positive effect on children's performances in school.She decides to repeat the same study to see if she obtains similar results.She is engaging in:

Pablo is conducting research and trying to determine whether he should monitor the presence versus the absence of a behavior or how long a behavior occurs.What approach to research is he most likely using?

Psychologist Jean Piaget observed children to see how they solved problems.Over the course of many studies,he was able to spot general patterns of behavior.This led him to connect different concepts and behaviors within a single:

Dr.Sherman is studying marital relationships and wants to be able to determine which types of couples are at the highest risk for divorce.Which of the four primary goals of science is he addressing?

Operational definitions make it possible for researchers to:

The range and standard deviation are examples of:

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 a(n):

How is a meta-analysis different from other types of studies?

In which of the following types of study do researchers examine the extent to which variables are naturally related in the real world (that is,there is NO attempt by the researcher to influence the relation among the variables)?

Why is the range often the LEAST useful measure of central tendency?

Researchers assess people's performances with respect to a given behavior at the beginning of a study before manipulating a variable so they can identify what happens to behavior when they manipulate a variable.The use of control groups and groups that experience a manipulation of a variable is characteristic of:

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

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

Which of the following sampling techniques gives each member of the population an equal and independent chance of being selected to participate?

When an experiment lacks the proper control,which of the following unintended variables can influence the outcome of a study?
