Validities
subjective ways to measure construct validity?
content and face validity
name all 4 big validities
internal validity
external validity
construct validity
statical validity
measured variables: predicator variables and dependent variables
manipulated variables: randomly assigned variables
What is opened ended mean
Respondents can answer how they want
B in Bruso mean
brief
what are empirical ways to access construct validity
criterion validity
- concurrent validity
- predictive validity
convergent validity
discriminant validity
What Internal Validity ?
How much we have ruled out other explanations for their relationships so we can say the only remaining explanation is x causes y
what is a conceptual variable
the name of the abstract concept being studied
what does close ended items mean?
respondents must choose from a set response option
R in relevant mean
relevant to the construct aka the research question
what is criterion validity
what is external validity
how much the results generalize (apply to people in situations beyond those in the study)
what is a conceptual definition
a careful theoretical definition of the construct
What is forced choice items
Choose from the giving options(a type of closed ended item)
U in BRUSO mean
Unambiguous
discriminant validity
hoe much the measure dos does not correlate with the measure to dissimilar constructs
what construct validity
how well a construct is operationalized
what is a operational definition
how the construct is specially measure or manipulated in a study
what verbal labels called
anchors
S in BRUSO
Specific : about the topic and without double barreled questions
what is convergent validity
how much the measure statistically correlates with the measure of similar/ the same construct
what statistical validity
How well statistics support the claim
what happens when the rating scale is odd vs even
when the rating scale is odd there is a neutral point vs when it is even you must choose a side
What does the O in BRUSO mean
Objective: Does not reveal researchers' personal opinions and no leading questions.
