1
Q

A variable whose levels are categories

A

Categorical variable

2
Q

Concurrent validity

A

An emperically supported type of measurement validitythat represents the extent to which a measure is related to a concrete, simultaneous outcome that it should be related to.

3
Q

The extent to which a measure captures all parts of a defined construct.

A

Content validity

4
Q

An emperically supported type of measurement validity that represents the extent to which a measure is associated with other measures of a theoretically similar construct

A

Convergent validity

5
Q

a number from -1 to 1 used to indicate the strength and direction of an association

A

Correlation coefficient, r

6
Q

Cronebach’s alpha

A

a correlation-based statistic that measures a scale’s internal reliability

7
Q

An empirically supported type of measurement validity that representsthe extent to which a measure does not associate strongly with measures of other, theoretically different constructs.

A

Discriminant validity

8
Q

The extent to which a measure is subjectivelyconsidered a plausible operationalization of the conceptual variable in question

A

Face validity

9
Q

Internal reliability

A

In a measuring instrument that contains multiple items, the consistency in pattern of answers no matter how the question is phrased

10
Q

A quantitative measurement scale that has no true zero and in which numbers are equally spaced.

A

Interval scale

11
Q

Observational measure

A

A variable whose values can be recorded as meaningful numbers

12
Q

Ordinal scale

A

A quantitative measurement scale with levels representing a ranked order. It is unclear the distance between variables

13
Q

A variable measured by recording biological data

A

Physiological measure

14
Q

Predictive validity

A

An empreically supported type of measurement validitythat represents the extent to which a measure is related to a concrete, future outcome that it should be related to

15
Q

Quantatative variable

A

A variable that can be recorded in numbers

16
Q

A quantitative scale in which the numerals have equal intervals and a true zero

A

Ratio scale

17
Q

consistency of a measure

A

reliability

18
Q

A method of measuring a variable in which people answer questions about themselves in a questionare or interview

A

self-report method

19
Q

A description of an association including how closely the data points in a scatterplot cluster along a line of best fit.

A

strength

20
Q

the consistency in results every time a measure is used

A

Test-retest reliability
