What is validity?
Your friend Dominic is complaining about having to take the Graduate Record Examination (GRE), a test that is required to go to graduate school and is similar to the ACT and SAT. He complains, “Tests like the GRE don’t really measure how well people actually do in graduate school.” By questioning whether the GRE predicts a related behavior (performance in graduate school), Dominic is questioning the ______________ of the test.
What is criterion validity?
A researcher plans to use the following scale to measure narcissism:
This scale would be said to have _____ internal reliability.
What is low?
A researcher is planning to measure resilience by having participants work on an impossible puzzle. She will record the order in which participants give up (e.g., the person who gives up first, second, third, etc.). The dependent variable uses a ______ scale.
What is ordinal?
A researcher wants to know whether using social media can increase feelings of belonging. She could use a _________ scale to determine how much the participant agrees with statements about belongingness.
What is a Likert scale?
A researcher intends to measure relationship satisfaction using a new self-report measure. The measure demonstrates high internal and test-retest reliability. Based only on this evidence, the researcher can conclude that they have high ______ but can make no claims about _______.
What is reliability and validity?
We can use known information about groups to establish this kind of validity.
What is criterion validity?
If a researcher gives a measure to a group of participants at the start of the semester and the end of the semester and finds the scores are similar, the measure would be said to have this type of reliability.
What is test-retest reliability?
What are test-retest and internal reliablitiy?
Asking participants how stressed they are from stressed to calm would be an example of this.
What is semantic differential? Operationalizing?
Dr. Rodriquez is concerned about the validity of the measure of narcissism recommended by her colleague. She sends a copy of the measure to the faculty members in her psychology department to look at, and they all tell her it looks like it will measure narcissism. She now has evidence of ____ validity.
What is face validity?
Participants’ self-esteem scores are weakly correlated (r = .05) to their scores on a measure of physical health. This information helps to provide _______ validity.
What is discriminant validity?
When scatterplot data trend extremely close to forming a perfectly diagonal line, we would say this indicates a _______ relationship.
What is strong?
A researcher comparing their survey results to those of other similar well-established surveys would be looking at ________ and ________ validity.
What is discriminant and convergent validity?
A researcher wants to conduct an experiment in which they see if public speaking increases participant stress levels. They _______ them to one of two conditions, give or listen to a 5-minutes speech and then assess their stress levels.
What is randomly assign?
Reliability is necessary, but not sufficient for _____.
What is validity?
Participants’ self-esteem scores are highly correlated (r = .75) with their scores on a measure of self-confidence. This information helps to establish _______ validity?
What is convergent validity?
If we used a scatterplot to represent interrater reliability, each dot or datapoint would represent this.
What is a participant?
