1

## What does blind mean?

### When the researcher and/or participant are unaware of information that might bias their responses.

2

## What is categorical data synonymous with?

### Synonymous with nominal data.

3

## What is concurrent validity?

### Assessing a measure by its correlation with a criterion that has already been measured or can be measured simultaneously.

4

## What is convergent validity?

### Occurs when different studies, using different operational definitions, produce similar findings.

5

## What is criterion?

### The variable that we are attempting to predict in regression.

6

## What is criterion-related validity?

### Measures, such as predictive and concurrent validity measures, that are established by correlation with known criterion measures.

7

## What is effective range?

### The range over which the dependent measure accurately reflects the level of the dependent variable.

8

## What is internal consistent reliability?

### Index of the homogeneity of the iterms of a measure.

9

## What is interrater reliability?

### Index of the consistency of ratings between separate raters.

10

## What is the interval scale?

### Scale of measurement in which the distance between adjacent scores is the same anywhere on the scale, but zero is not a true zero.

11

## What is measurement error?

### Any inaccuracy found in the measurement of a variable.

12

## What is the multimethod approach?

### In research, using several measures of a single concept to increas confident in the results.

13

## What is nominal data?

### Data that are frequencies of particpants in each category.

14

## What is the nominal scale?

### Scale of measurement in which the scores are categories.

15

## What is objective measure?

### Any measure that requires little or no judgement on the part of the person making the measurement.

16

## What is the operational definition?

### Procedures used to measure or manipulate a variable.

17

## What is ordered data?

### Data produced by ordinal scales of measurement.

18

## What is an ordinal scale?

### Scale of measurement in which the scores can be rank ordered, but the distance between adjacent scores varies.

19

## What is plagerism?

### The deliberate distortion of information by presenting another person's work as one's own.

20

## What is predictive validity?

### The degree to which a measure can accurately identify a person's future.

21

## What is a predictor measure?

### The variable used to predict the criterion measure.

22

## What is a ratio scale?

### Scale of measurement in which the intervals between scores are equal and the zero point on the scale represent a zero level of the quality being measured.

23

## What is reliability?

### Index of the consistency of a meaning instrument in repeatedly providing the same score for a given participant.

24

## What is response set bias?

### Any tendency for a participant to distort responses to a dependent measure and thus create measurement errors.

25

## What are scale attenuation effects?

### Any aspect of the measuring instrument that limits the ability of the instrument to make discrimination at the top of the scale.

26

## What are scales of measurements?

### How well scores on a measurement instrument match the real number system.

27

## What is score data?

### Data produced by interval and ratio scales of measurement.

28

## What is social desirability?

### Response set in which participants tend to say what they believe is expected of them.

29

## What is test-retest reliability?

### Index of the consistency in scores over time.
