Measurement

Casey is evaluating humor in individuals by how many jokes they say. He scores each person and adds up the total. Casey's advisor tells him that he needs to have another person also score the same individuals, and that he should then compare the scores given.

This is checking for:

• test-retest reliability

• convergent validity

• inter-rater reliability

• predictive/

  concurrent validity

Dave is worried if the IQ test he is using is a sound measurement of intelligence. To check this, he has the same participants take the IQ test two times, both a month apart to check for consistency.

• alternate forms reliability

• test-retest reliability

• convergent validity

• content validity

Using different versions of a survey to compare results for reliability is

checking for

• stablity

• equivalence

• internal consistency

• precision

Which word describes how well a an instrument measures the concept being examined.

• reliability

• consistency

• readability

• validity

The extent to which a study can be generalized beyond the study sample is?

• internal validity

• external validity

• accuracy

• reliability

A threat to external validity includes:

• the setting of the study

• a large sample size

• operational defintions

• test-retest design

The difference between the true measure and what is actually measured is:

• stability

• measurement error

• equivalence

• convergence
