Exam 5: Variables, Reliability, and Validity

Any change observed in the dependent variable is a result of the __________.

A subject variable is a characteristic or attribute of a participant that can impact a study.

Subject variables are true independent variables

In this reliability assessment procedure, you repeat the split-half method multiple times and obtain an average of the correlation coefficients.

What variables are essential to research?

with an Are You Equipped exercise highlighting the debate between Apple and Microsoft.In this example, the decisions of the buyers served as the __________.

Drews et al.2008) manipulated driving conditions i.e., driving while talking to a friend on the cell phone and driving while talking to a friend in the car) to see if this influenced the number of driving errors committed.Participants completed the task on a driving simulator.In this design, the driving condition served as the __________.

The experimental group is the group of participants exposed to the __________.

Consider the following research question, "Does the type of advertisement influence the level of interest in the toothpaste?" To answer this question, a marketing researcher has participants listen to the radio advertisement or watch the television advertisement about the toothpaste.Next, the researcher asks all participants to indicate their interest in buying the toothpaste.In this example, what is the independent variable?

The following terms are all examples of reliability measures: split-half, test-retest, construct, internal consistency and parallel forms.

A subject variable is similar to a dependent variable in that it is predicted to influence responses.

Imagine your professor asked the following question, "how stressed are you about taking research methods?" In this example, what would be the variable?

If a researcher is comparing a new method or technique to the current method or technique, what would participants in the control group be exposed to?

The dependent variable is __________.

Think about variables used in research.Of the following terms, which term below fits least well?

Internal validity is the extent to which obtained results can be generalized to other settings.

__________ is a reliability assessment where a measure is tested on two different occasions.

The following terms are all examples of validity measures: split-half, test-retest, internal consistency and parallel forms.

__________ is a reliability assessment where a measure is divided into two halves and the halves are compared.

The experimental group is the group of participants exposed to the independent variable.
