Test validity is the consistency of a measure with a criterion; the degree to which a measure actual measures what is claimed.
100
What is Test-retest reliabilty?
Giving the measure twice and reporting consistency between scores.
100
What has an actual Zero Point?
Ratio Scale
200
What is the Nominal Scale?
Use of numbers as simple identifications of variables.
200
What does reliability mean?
Reliability means getting the same results every single time.
200
What is Experimental Validity?
Experimental validity refers to the absence of errors that prevent researchers from drawing unequivocal conclusions.
200
What is Alternate forms Reliability ?
Constructing different forms of the same test from a common pool of measurement items, giving them to a group of people, and determining the degree of consistency between them .
200
What equals consistancy?
Reliability
300
What is the Ordinal Scale?
Measurement involving rank order on some variable.
300
What is an example of Reliability?
1.Stepping on the scale multiple times.
2.Same amount of liquid in every manufactured bottle
3.Same amount of slices in a pizza pie
300
What is the Essential question that must be asked in regards to Validity?
Are you measuring what your supposed to measure?
300
What is Split-half Reliability?
Computing measurement reliability by dividing a test into two parts, scoring them separately, and checking the consistency between the two scores.
300
When asking this question, what are we referring to ?
"Are you measuring what your supposed to measure?"
Validity
400
What is the Interval Scale?
Assignment of numbers to items as a matter of degree such that “the intervals between the numbers are EQUAL in size.”
400
What is Reliabilty?
The internal consistency of a measure
400
What is promised when you have validity?
Reliability.
400
What is Item to total Reliability?
Computing measurement reliability by correlation of items with the total test.
400
What is the goal of measurements?
To make sure that however we measure, our measurements are both reliable and valid.
500
What is the difference between the Interval Scale and the Ratio Scale ?
The Interval scale has a arbitrary zero point, and the Ratio scale has an actual zero point.
500
What must you have in order to have Reliabilty?
Validity.
500
What is an example of Validity ?
Did they ACTUALLY measure whether or not it was faster to walk or drive to school.
500
What is Intercoder Reliability ?
Determining the consistency of different raters who respond to the same events by using some sort of check sheet.
