Survey (def)
Set of fixed-format items that is completed by respondents at their own pace
-A method of collecting info from a sample of consumers predominantly by asking questions
Survey (advantages)
cheaper, most honest responses, less experimenter bias
Survey (disadvantages)
response rate may be low, less flexible than interviews
Sampling (def)
the selection of people to participate in a research project
Representative sample
one that is approximately the same as the population of interest in every important respect
Sampling (goal)
Goal: to use these people to make inferences about a larger group of individuals
WEIRD
(Western, Educated, Industrialized, Rich, Democratic)
Focus Groups (what are they?)
- Gatherings of several people with moderator to discuss product/service/brand/company
- Moderator must be objective, socially skilled, knowledgeable
- Open discussion is encouraged
- Often recorded and watched later or watched live through 2-way mirror
Ethnographic research (What is it?)
- Making observations of behavior and recording those observations in an objective manner
- Subjects observed while using product in own home or natural environment
- -subjects may or may not be aware of the observation
Ethnographic research (Most useful when)
- you want to see how people behave in natural environments
- trying to generate new ideas or insights
- investigating complex social settings
Ethnographic research (least useful when)
testing hypotheses
Correlational research
- Used to see if there’s a relationship between 2 variables (usually measured in survey)
- Display data using scatterplots
- Pearson correlation coefficient (r-value) ranges from -1.0 to +1.0
- – varies in terms of valence and strength

- – varies in terms of valence and strength
3 Factors necessary for causation
- Correlation
- Temporal antecedence
- No third factor driving both
Suprus correlation
- spurus = fake/artificial
- This is the danger of data mining
- Lots of things are correlated, but not really related
Experimental research (what is it for?)
used to examine cause and effect
Experimental research (steps)
- Identify issue or question of interest
- Review the relevant theories and research
- Develop hypothesis
- Identify and operationalize the independent and dependent variables
- Conduct the experiment
- Analyze and interpret results
Independent variable
the factors manipulated in a study to see if they influence the dependent variable
Dependent variable
the factors measured to see if they are affected by the independent variable
Experimental effects
- Main Effect: When the levels of a factor significantly influence a dependent variable
- Interaction: The levels of one factor influence the dependent variable differently depending on the levels of a second factor
Main Effect
When the levels of a factor significantly influence a dependent variable
Interaction
The levels of one factor influence the dependent variable differently depending on the levels of a second factor
Interaction
The levels of one factor influence the dependent variable differently depending on the levels of a second factor
Exposure
The process by which the consumer comes into contact with a stimulus
