MKT 360 Exam 2 Study Guide
administrative error
(non-sampling error) An error caused by the improper administration or execution of the research task. ex: incorrect data entry, interviewer error, interviewer cheating
affective (emotional) components
(physiological measure) these measures provide: - a means of assessing affect without verbally questioning of the respondent - a gross measure of like or dislike
GSR
(physiological reaction) measure of involuntary changes in the electrical resistance of the skin
facial EMG
(physiological reaction) used to observe emotional reactions via muscle activity around the mouth
eye-tracking
(physiological reaction) used to observe eye movements
social desirability bias
(response bias) Bias in responses caused by respondents' desire, either conscious or unconscious, to gain prestige or appear in a different social role. luxury, high-end goods
interviewer bias
(response bias) The presence of the interviewer influences respondents' answers.
extremity bias
(response bias) some individuals tend to use extremes when responding to questions
acquiescence bias
(response bias) tendency for a respondent to try to agree with the viewpoint of a survey
4 levels of scale measurement
1. Nominal 2. Ordinal 3. Interval 4. Ratio
response rates
The number of questionnaires returned and completed divided by the number of sample members
measurement
The process of describing some property of a phenomenon of interest, usually by assigning numbers in a reliable and valid way.
content analysis
The systematic observation and quantitative description of the manifest content of communication.
attribute
a single characteristic or fundamental feature of an object, person, situation, or issue - the measures of these are often combined to represent some less concrete concept
absolute zero
defining characteristic in determining between ratio and interval scales
disadvantages of surveys
easy to make errors (causes misleading results)
sampling error
error that occurs because the research only has a sample to calculate parameters and not the entire population sample mean is not the same as population mean
confound
extraneous variable that might affect the results of the experiment
placebo
false experimental treatment
experimental group
group in which an experimental treatment is administered
control group
group in which no experimental treatment is administered
true experiment
has both experimental group and control group
experimenter bias
if participants recognize the experimenter's expectation or demand, they are likely to act in a manner consistent with the experimental treatment (even slight nonverbal cues may influence reactions)
brand equity scale
image, value, trust, attachment, performance
relevancy
in relation to a questionnaire, all information collected addresses a research question that will help the decision maker address the current marketing problem
inaccurate responses
inability to respond telescoping- respondent misremembers something averaging- can't remember an exact amount so they try to average what they most likely did omission- completely forgot cannot formulate adequate answer
matching
involves assigning subjects in a way that a particular characteristic is the same in each group
internal validity
is the experimental variable truly responsible for any variance in the dependent variable? Does x really cause y? if you are more concerned about this, lab experiment might be best
disadvantages of online surveys
lack of anonymity, spam filters
experiments (causal research)
marketing experimenter manipulates one or more independent variables and holds constant all other possible independent variables while observing effects on dependent variables
ordinal scale
may be developed by asking respondents to rank order (from most preferred to least preferred) a set of objects or attributes
sample survey
more formal term for a survey emphasizing that respondents' opinions presumably represent a sample of the larger target population's opinion
validity
the accuracy of a measure or the extent to which a score truthfully represents a concept
external validity
the accuracy with which experimental results can be generalized beyond the experimental subjects (if you take the results out of the lab, with they hold up in the real world?) if you are more concerned about this, field experiments might be better
subjects
the name used for respondents in an experiment
randomization
the random assignment of subjects and treatments to groups
laboratory experiment
the researcher maximizes control over the research setting and extraneous variables
paired comparisons
the respondents are presented with two objects at a time and asked to pick the one they prefer
demand characteristic
an experimental design element that unintentionally provides subjects with hints about the research hypothesis
composite scales
assign a value based on a mathematical derivation of multiple variables
index measure
assigns a value based on how much of the concept being measured is associated with an observation - it is often formed by putting several variables together
graphic rating scales
present respondents with a graphic continuum respondents are allowed to choose any point on the continuum to indicate their attitude
operationalization
process that involves identifying scales that correspond to variance in the concept
types of info gathered during surveys
product use, desirables features, media habits assess consumer knowledge and awareness of products, brands, or issues and to measure consumer attitudes, feelings, and behaviors
advantages of surveys
quick, inexpensive, efficient, accurate, flexible
main effect
refers to the experimental difference in means between the different levels of any single experimental variable
ratio scales
represent the highest form of measurement in that they have all the properties of interval scales with the additional attribute of representing absolute quantities; characterized by a meaningful absolute zero
survey
represents a way of describing public opinion by collecting primary data through communicating directly with individual sampling units
nonrespondents
sample members who do not provide input in the research for any number of reasons
factors that affect the choice of survey method
sampling, type of population, question form, question content, response rate, costs, available facilities, duration of data collection
advantages of online surveys
speed, lower cost, faster turn around time, more flexibility, less manual processing
nonresponse bias
statistical difference between a survey that includes those who responded and those who failed to respond
test units
subjects whose responses to the experimental treatment are measured (people are most common)
scales provide:
- A range of values that correspond to different values in the concept being measured - Correspondence rules that indicate that a certain value on a scale corresponds to some true value of a concept, hopefully in a truthful way
interval scales
- Have both nominal and ordinal properties - Capture information about differences in quantities of a concept - do not exactly represent some phenomenon
ordinal scales
- Have nominal properties - Allow things to be arranged based on how much of some concept they possess - Include ranking scales - Are somewhat arbitrary
what can be observed
- Physical movements - Verbal behavior - Expressive behavior and physiological reactions - Spatial tensions and locations - Temporal patterns - Physical objects - Verbal and pictorial records - Neurological activity - Internet activities - Geographical information - Physical distribution
category scales
- Rating scales that consist of several response categories, often providing respondents with alternatives to indicate positions on a continuum - measure attitude with greater sensitivity than a two-point response scale
reliability
- an indicator of a measure's internal consistency - when the measuring process provides reproducible results - a measure is ____ when different attempts at measuring something converge on the same result
ways to reduce demand characteristics
- incorporate experimental disguise (placebo) - isolate experimental subjects - use a "blind" experimental administrator - administer only one experimental condition per subject (non-repeated measures) - paying for performance might create demand effects
behavioral intention
- intentions that represent the behavioral expectations of an individual toward an attitudinal object - the component of interest to marketers is buying intention, a tendency to seek additional information, or plans to visit a showroom
4 important design elements of experiments
- manipulation of independent variable - selection and measurement of the dependent variable - selection and assignment of experimental subjects - control of extraneous variables
multi-attribute approach
- take belief scores assessed with some type of rating scale - multiply each belief scare by an evaluation also supplied using some type of rating scale - sum each resulting product advantages: results can provide management with feedback on the relative attitude scores and identify characteristics that are most in need of being improved
formatting
-decide on open-ended vs closed format -select the format and scale type fo each question
pretesting & correcting problems
-make sure that the respondents understand the directions -time responses -modify poor questions/unclear directions
planning
-revisit the research objectives -find relevant info from other sources -agree on analysis
wording
-simplify vocab -remove double-barreled questions -avoid leading/loaded questions -clarify instructions
sequencing & layout decisions
-use screening questions to avoid inaccurate responses -make sure that the questionnaire has a smooth, logical glow -start with broad questions, then become more specific -place demographic questions at the end of the survey
observer bias
A distortion of measurement resulting from the cognitive behavior or actions of a witnessing observer (in direct observation)
semantic differential
A scale type that has respondents describe their attitude using a series of bipolar rating scales - validity of this depends on finding scale anchors that are semantic opposites
direct observation
A straightforward attempt to observe and record what naturally occurs; the investigator does not create an artificial situation.
typical number of scale categories
5-7 categories
self-administered questionnaires
surveys in which the respondent takes the responsibility for reading and answering the questions without having them stated orally by an interviewer
observation
systematic process of recording the behavioral patterns of people, objects and occurrences as they take place can be a useful part of either qualitative or quantitative research
categorical variables
take on a value to represent some classifiable or qualitative aspect
repeated measures
Experiments that expose an individual subject to more than one level of an experimental treatment involve a repeated measures design one subject is exposed to more than one of the conditions (smaller sample sizes)
self-report scales
Involve gaining a respondent's structured response to some specific query or stimulus Researchers can ask respondents to rank, rate, sort, or choose one of multiple responses
response bias
a bias that occurs when respondents either consciously or unconsciously answer questions with a certain slant that misrepresents the truth 2 categories: deliberate falsification, unconscious misrepresentation
interaction effect
a change in a dependent variable due to a specific combination of independent variables
contrived observation
Observation in which the investigator creates an artificial environment in order to test a hypothesis. ex: secret shoppers
visible observation
Observation in which the observer's presence or mechanical measurement device is obviously known to the subject.
hidden observation
Observation in which the subject is unaware that observation is taking place. these are free from errors such as social desirability bias or memory problems
nominal scales
Represent the simplest type of scale and assign a value to an object for identification or classification purposes - value can be but does not have to be a number since no quantities are being represented
constant-sum scale
Respondents are asked to divide a fixed number fo points among several attributes to indicate their relative importance - if instructions followed correctly, the results will approximate interval measures
likert scale
Respondents indicate their own attitudes by checking how strongly they agree or disagree with statements, ranging from very positive to very negative attitudes - researchers assign scores to each possible response
pretesting
Screening procedure that involves a trial run with a group of respondents to iron out fundamental problems in the survey design.
non-sampling error
all other types of error that could exist (error on researcher, error on respondent) error is observed in both census and sample
central location interviewing
telephone interviews conducted from a central location, allowing firms to hire a staff of professional interviewers and to supervise and control the quality of interviewing more effectively
experimental treatment
term referring to the way an experimental variable is manipulated
attitude
an enduring disposition to respond consistently in a given manner to various aspects of the world, including persons, events, and objects (ABC model)
mechanical observation
can very accurately record behavior that is routine, repetitive, or programmatic types: -television, radio, and digital monitoring -monitoring web traffic -scanner-based research -camera surveillance -smartphones
inventories
counting and recording physical inventories through retail or wholesale audits
demand effect
occurs when demand characteristics actually affect the dependent variable
respondents
people who answer questions during a survey
types of surveys
personal interview (face-to-face) telephone interview self-administered survey (mail, email)
process of questionnaire design
planning formatting wording sequencing & layout decisions pretesting & correcting problems
field experiment
the study takes place in a natural environment (subjects dont know they have taken part in an experiment)
artifacts
the things that people made and consumed within a culture that signal something meaningful about the behavior taking place at the time of consumption
bipolar adjectives
words such as "good" or "bad", "modern" or "old-fashioned", "clean" or "dirty"; anchor both ends (or poles) of the scale
disadvantages of observation
• Behavior can be observed, but motives cannot • Analytical models do better with predicting behavior than explaining it • Observation period is often too short
