seeks no additional information from the respondent

|
open-ended question
|
|
interviewer asks for additional information to encourage the respondent to provide information beyond the initial and possibly superficial first comments
EX: Did you have any other thoughts or reactions to the advertisement? Pros: elicits complete answers Cons: Difficult to code and interpret |
Probed open-ended question
|
|
has only two response options, such as yes or no

EX: If you were to buy a DVD player tomorrow, which brand would you be most likely to purchase? Would it be: a. Panasonic b. General Electric c. Sony d. JVC e. Some other brand Pros: allows for broad range of possible responses. simple to administer and code Cons: may alert respondents to response options of which they were unaware. Must distinguish "pick one" from "pick all that apply" |
Multiple category closed-ended question
|
|
scale may be purely numerical or only the endpoints of the scale are identified
EX: on a scale of 1 to 7, how would you rate the Sony DVD player on ease of operation? Pros: Allows for degree of intensity/feelings to be expressed. Simple to administer and code Cons: Respondents may not relate well to the scale |
Unlabeled scaled-response question
|
|
uses a scale chosen by the researcher to measure the attributes of some construct under study
EX: Do you disagree, strongly disagree, agree, or strongly agree with the statement 'Song DVD players are a better value than General Electric DVD players'" Pros:allows for degree of intensity/ feelings to be expressed. simple to administer and code. Respondents can relate to the scale Cons: scale may be unfamiliar or have more levels than respondents can relate to easily |
labeled scaled-response question
|
|
determining how much of a property is possessed by an object
|
measurement
|
|
specific features or characteristics of an object that can be used to distinguish it from another object
- objective properties- physically verifiable - subjective properties - cannot be directly observed |
property
|
|
the consumer
|
object
|
|
physically verifiable characteristics such as age, income, number of bottles purchased, store last visited.
are observable and tangible |
objective properties
|
|
unobservable and intangible onto a rating scale through the process of scale development
- mental constructs such as a person's attitude or intentionss |
subjective properties
|
|
description, order, distance, and origin
|
scale characteristics
|
|
use of a descriptor, or label, to stand for each "unit" on the scale
- yes, no, male, female, etc. |
description
|
|
relative sizes of the descriptors are known allowing us to say one is "greater/less than" the other.
|
order
|
|
differences between the descriptors are known
- there is a 10 degree difference between 90 and 100 degrees |
distance
|
|
there is a true, natural zero
- there is a zero level of dollars, market share, sales. |
origin
|
|
those that use only labels
- check all brands you would consider purchasing - abercrombie & fitch - hollister - ruehl's - aeropostale - american eagle - marc ecko |
nominal scales
|
|
those with which the researcher can rank-order the respondents or responses
- please rank each brand in terms of your preference - abercrombie & fitch - hollister - ruehl's - aeropostale - american eagle - marc ecko |
ordinal scales
|
|
those in which the distance between each descriptor is equal
- please rate each brand on a 1-7 scale in terms of its overall performace, with 1= very poor and 7= very good - nike - puma - reebok - new balance |
interval scales
|
|
ones in which a true zero exists
- please indicate your age x ----- years |
ratio scales
|
|
the scale affects what may or may not be said about the property being measured
- if you wish to calculate an average, you must use an interval or ratio scale - if you have a nominal or ordinal scale, you must summarize the results with a percentage or frequency distribution |
why the level of a measurement scale is important
|
|
respondents are asked to indicate their degree of agreement or disagreement on a symmetric agree-disagree scale for each of a series of statements
|
likert scale
|
|
psychographics inventory- which takes into account the avlues and personality traits of people as reflected in their unique activities, interests, and opinions (AIOs) toward their work, leisure time, and purchases
|
lifestyle inventory
|
|
specialized scaled-response question format that has sprung directly from the problem of translating a person's qualitative judgments into quantitative estimates
|
semantic differential scale
|
|
when a researcher develops questions for his or her questionnaire, he or she uses an intuitive form of judgment to evaluate the validity of each question
|
face validity
|
|
respondents responds in the same or a similar manner to an identical or nearly identical measure
|
reliability
|
|
truthfulness of responses to a measure
|
validity
|
