### Reliability and validity should be considered...

before you start analyzing data

reliability

validity

are not valid

### Reliability and validity specifically relate to

the quality of the data themselves

### The outcome variable in an analysis is called...

the dependent variable

### The predictor variable in an analysis is called

the independent variable

nominal

ratio

### This is the level of measurement where outcomes are based on some underlying continuum where it is possible to speak about how much more a higher performance is than a lower one:

interval level of measurement

### This is the level of measurement where outcomes can only be placed into unranked categories

nominal level of measurement

### This is the level of measurement where outcomes can be rank ordered.

ordinal level of measurement

### This is the level of measurement where outcomes are based on some underlying continuum that also contains a true or absolute zero.

ratio level of measurement

ratio

### Moving from the nominal to the ratio levels of measurement, your data becomes...

more precise and detailed

### Which of the following is concerned with monitoring estimates of present performance and predictions of future performance?

predictive validity

content validity

### If you want to know that a test measures some underlying psychological construct, what type of validity evidence would you want to collect?

constrict validity

### If you correlate scores from your test with some other valid measure that assesses the same set of abilities, what type of validity evidence are your collecting?

criterion validity

content validity

### What is the key to establishing Criterion validity?

quality of criterion

### Which of the following is NOT a measure of validity?

parallel forms validity

content validity

### This type of validity is determined by determining the association between the test scores and some specified present or future criterion.

criterion validity

### This type of validity is based on the judgment of how well a test reflects an underlying idea

construct validity

### High school class rank is highly correlated with college GPA. This is an example of what type of validity

predictive validity

observed score

test-re test

### The correlation between scores from time 1 and time 2 is called:

test- re test reliability

### The correlation between two forms of the same test is called:

parallel forms reliability

### Cronbach'a Alpha is used to calculate the following

internal consistency reliaility

### The number of agreements between your two raters divided by the total number of possible agreements is the way to calculate:

interrater reliability

### This is the type of validity that examines how well a test outcome is consistent with a criterion that occurs in the present.

concurrent criterion validity

### This is the type of validity that examines how well a test outcome is consistent with a criterion that occurs in the future.

predictive validity

true score

### The actual or measured score is called:

the observed score

the error score

1.00

inter ratee

reliable

### Which of the following is NOT a measure of reliability?

multiple forms reliability

### When we calculate reliability, we know the observed score. What are the two unknown components of the reliability equation?

true and error scores

### Inter-rater reliability measures consistency _________________.

from rater to rater

A.

### Test-Retest reliability is an example of which of the following?

measure of reliability over time

### Parallel forms reliability is an example of which of the following?

measure of equivalence

### Inter-rater reliability is an example of which of the following?

measure of agreement

0.90

### What are the four levels of measurement?

nominal, ordinal, interval, ratio

### The maximum level of validity possible is equal to:

the square of the reliability coefficient

### Which level of measurement is concerned only with the characteristics of an outcome that fits into a category?

nominal level of measurement

### If you are interested in describing the order of variables along a continuum, what level of measurement would you use?

ordinal level of measurement

### If the underlying continuum we are measuring assumed equal intervals, at what level of measurement is the associated variable being measured?

interval level of measurement

### Which of the following levels of measurement provides the most information about a variable?

ratio level of measurement

Lee J. Cronbach

measurement

### What is the difference between the true score and the observed score?

observed score: what you actually get on the test
true score: the true , 100% accurate reflection of what you really know.
