Scales that labels mutually-exclusive characteristics
What is a nominal scale?
100
This hypothesis states that there is no effect of IV on DV
What is the null hypothesis
100
"These questions all appear to be on-topic" is an assessment of
What is face validity
100
When a single individual takes the same test at two different times
What is test/retest reliability
100
When each person in a population has a known chance of being selected for a sample
What is probability sampling
200
A scale that indicates relative quantity
What is an ordinal scale?
200
This alternative hypothesis specifically states that condition A will be greater than condition B
What is a one-tailed hypothesis?
200
Criterion validity assesses this type of DV
What is a self-report measure
200
When scores from two judges are correlated with each other
What is inter-rater reliability
200
When every person in a population has an equal chance of being selected for the sample
What is simple random sampling
300
This scale has a true zero point
What is a ratio scale?
300
This error is when you find a statistically significant result when the IV does not, in fact, influence the DV
What is a Type I error
300
When two different operational definitions of the same conceptual variable are assessed simultaneously
What is convergent construct validity
300
This measure assesses how well each individual item on a scale correlates with every other item on the scale
What is Cronbach's alpha
300
This type of sampling is most useful when the population of interest is very small
What is snowball sampling
400
Interval and ratio scales are both considered
What is continuous measures?
400
In the real world, the IV actually influences the DV; In your research study, you found a statistically significant result. The inference drawn will be
What is a correct inference?
400
When an investigator shows that scores on an IQ test are not related to prior education
What is discriminant construct validity
400
This measure of inter-rater reliability accounts for both chance agreement and degree of disagreement
What is Cohen's kappa
400
All subgroups are represented in equal numbers in the sample even though the population includes unequal numbers within each subgroup.
What is disproportionate stratified sampling
500
Reaction time and response frequency are examples of this type of scale
What is an interval scale?
500
The likelihood of detecting a true effect of IV on DV
What is statistical power
500
A question of whether the results from a research study will "hold-up" in the real world
What is external validity
500
These psychological constructs would not be expected to have high alternate-forms reliability
What are states
500
This type of sampling is most useful when a sampling frame is unavailable for the whole population
