Q

*continuous

A

rate object by posing mark at appropriate position on line

21
Q

*likert

A

strongly dis to strongly agree scale - neutral most likely to switch brnads

22
Q

*sematic

A

seven point raitng

23
Q

*staple

A

vertical scale ten categories from -5 to 5

24
Q

*balanced scale

A

extremely good, v good, good, somewhat good, bad, v bad, extremely bad

25
*unbalanced scale
extreme good, v good, bad, v bad
26
develop multiple items scale
1. detemerine what u r going 2 measure 2. generate as many items as possible 3. ask experts to eval 4. determine attitudinal scale to be used 5. include items to validate scale 6. administer to initial sample (PRETEST) 7. Eval + refine items 8. optimize scale length
27
itemized scale descions
categories, balanced, odd.even, physical form
28
*reliability
event to which measures are free from random error
29
*test-retest
same scale device, same sample, same conditions
30
*alt-forms
btw 2 equivalent forms, but same subject
31
split-half
btw equivalent group of items responses in multi item measurement device
32
split-half
btw equivalent group of items responses in multi item measurement device
33
internal consistency reliability
extent to which summated parts of scale are consistent about characteristics being measured
34
coefficient alpha
average of all possible split half coefficents
35
***validity
extent measurement free from systematic error
36
content (face) validity
subjective but systematic eval of how well content represents measurement task at hand
37
*citerion
reflects if scale performs as expected
38
*construct
addresses construct of what the scale is measure i.e. brand loyalty
39
*convergent validity
scales correlate positily
40
*discriminate validit
scales do not correlate possitivly
41
*nomological
scales correlate in theoretically predicted ways in the measure of the different but related constructs
42
predictive validity
compares current w predicted measurements
43
concurrent valdiity
compares two different measurements at the same point in time from the same theme
44
if a measure is perfectly valid
it is also relaible
45
if a measure is unrelaible
not valid
46
reliable measuer
may or may not be valid
47
**reliability is a necessity but
but not sufficient condition for validity
48
select a scale based on
reliability, sensibility, geralizability, relevance
