INDEX< SCALES AND TYPOLOGIES
Most common in survey research and other quantitative methods
Often used in quantitative research because:
Difficult to devise a single measure of complex concepts
o Especially true with regard to attributes and
o Research devise several items, each providing some
indication of the variable.
*We look at the measuring excellence ranking 49 universities (not
all but a lot)
*now we know there are three categories (we looked at
comprehensive)… looks at 6 broad areas and looking at indicators.
This is really an index of an index… each braod category its an
index itself brought into another index. Indexes and Scales
A single indicator proides a valid and reliable measure of some
E.g marital status; # of children in a fmialy
Other variables are more difficult and complex to measure
Some mat require > 1 indicator of a variable
Some may involve a # of dimentions that calls for multiple
E.g compassion (feeling vs. action)
Some may be concerned with degree to which a variable is present.
Eg physically fit

Indexes and Scales: Differences
Way scores are assigned in each :
Index: accumulate scores assigned to individual attributes
scale: assign scores to patterns of responses
uses differences in intensity among the attributes of the same
variable to identify distinct patterns of response.
**ideally you want a scale score rather than the index score
because it has more information.. they will use the term index
