Measuring the truthfulness of an instrument. Does the instrument measure what it is supposed to measure.
What is validity?
100
The group of people who participate in a study.
What is the sample?
100
The questions on surveys that ask for basic information, such as age, gender, ethnicity, etc.
What are demographic questions?
100
The form given to individuals before they participate in a study that tells them the general nature of the study, and ensure they agree to participate.
What is an informed consent form?
200
Giving the same test on two different occasions.
What is test/retest reliability?
200
This assess whether a test looks valid on its surface.
What is face validity?
200
This allows each member of a population to have an equal opportunity to be chosen as part of the sample.
What is random selection?
200
A type of numerical scale often used in surveys developed by Renis Likert in 1932.
What is the Likert rating scale?
200
The variable that is measured.
What is the dependent variable?
300
This correlates scores on one half of a test with scores on the other half.
What is split-half reliability?
300
This assess the tests content to determine if it covers the behaviors that are to be measured.
What is content validity?
300
This sampling method finds participants wherever they can be found because it is convenient for the researcher.
What is a convenience sampling?
300
This research method establishes a cause-and-effect relationship.
What is the experimental method?
300
Lying to subjects about the true nature of a study because knowing the truth might affect their performance.
What is deception?
400
This uses two different yet equivalent forms of a test and assesses their relationship.
What is alternate-forms reliability?
400
This test whether an instrument accurately measures a theoretical construct or trait.
What is construct validity?
400
This type of sample is most similar to the population.
What is representative sample?
400
This method assess the degree of relationship between two variables.
What is the correlational method?
400
The group receives some level of the independent variable.
What is the experimental group?
500
This assessing the agreement of observations made by two or more judges.
What is interrater reliability?
500
This assesses if an instrument accurately predicts behavior or ability in a given area.
What is criterion validity?
500
When using this sampling technique each member of the population has a known probability of being selected for the sample.
What is probability sampling?
500
Research that compares naturally occurring groups of individuals, variables cannot be manipulated.
