question
Define marketing research
answer
- the function that links the consumer, the customer and the public to the marketer through information - used to identify and define market opportunities and problems - generate, refine and evaluate marketing performance and strategies - monitor marketing performance and make adjustments - improve understanding of marketing as a process - understand customers - FUNDAMENTAL to making business and marketing decisions, without research you are operating on assumptions and best guesses
question
Why is it important to define the marketing research problem appropriately?
answer
- problem definition is the most critical step in market research project - waste of time, money and effort if the problem is misunderstand or ill-defined - incorrect problem definition leads to irrelevant findings that lead to bias managerial decision making - have to understand the nature of the problem and the decision which management faces - only when the problem has been clearly defined can research be designed and conducted
question
What are the common types of errors encountered in defining a marketing research problem? What can be done to reduce the incidence of such errors?
answer
- defining the research problem too broadly makes it not actionable and does not provide clear guidelines for subsequent steps in the project - defining the research problem too narrowly - if too narrow it eliminates interesting options - how to avoid these: broad statement (provides perspective on the problem and acts as a safeguard against being too narrow) and specific components (focus on the key aspects of the problem and provide clear guidelines on how to proceed further, reducing likeilhood of being too broad)
question
Exploratory research
answer
- provides novel insights and understanding, clarifies issues - information needed is defined only loosely - research is flexible and unstructured - sample = small and non representative - analysis of primary data is qualitative - followed by further exploratory or conclusive research
question
Conclusive research
answer
- tests specific hypothesis and examine relationships - information needed is clearly defined - research process is formal and structured - sample is large and representative - data analysis is quantitative
question
Cross sectional design
answer
- at one moment in time - involves collection of information from any given sample of population elements only once - most common type of descriptive research - could be single or multiple
question
Longitudinal design
answer
- over time - type of research involving repeated measurements of the same variables from the same sample - unique benefit: detecting change
question
Why is it important to minimize total error rather than any particular source of error?
answer
It is important to minimize total error to rather than focusing on one because attempting to lessen one particular source often creates an even bigger error elsewhere
question
Example of minimizing total error:
answer
a researcher might try to minimize sampling error by using a bigger sample. While this could help, it creates more room for non sampling error such as interview error. non sampling errors are usually worse and harder to account for
question
Secondary data
answer
data is collected for purpose other than the problem at hand low cost, short collection time easily accessible can help identify, clarify of refine the problem might provide answers to a research problem might suggest research design for primary data collection can alert researcher to potential problems provides background info enhancing research credibility
question
Primary data
answer
data that is originated by a researcher for the SPECIFIC PURPOSE of addressing the problem at hand collected for the problem at hand involved and consuming collection process relatively high cost
question
Criteria for evaluating secondary data
answer
Who/what/what/when/how/are Who gathered the data? What was the purpose of the study? What information was collected? When was the information collected? How was the information collected? Are the data accurate?
question
Qualitative research
answer
gain understanding of the underlying reasons and motivations sample is a small number of non representative cases data collection = unstructured data analysis = non statistical
question
Quantitative research
answer
to quantify the data and generalize the results from the sample to the population of interest large number of representative cases data collection: structured data analysis: statistical recommend a final course of action
question
Depth interview
answer
detailed probing thoughts, beliefs, attitudes and feelings one on one structured, direct personal interview discussion of confidential, sensitive and embarrassing topics strong social norms exist and respondents might be easily swayed by the group complicated behavior professional interviewing (getting a large group at the same time is difficult) product consumption is experiential and sensory
question
Relevant factors for evaluating which survey method is best suited to a particular research project?
answer
task, situation, respondent
question
Task factors
answer
diversity of questions use of physical stimuli sample control quantity of data response rate
question
Situation factors
answer
data collection environment field force (interviewers/supervisors) interviewer bias speed (time to administer sample) cost
question
Respondent factors
answer
perceived anonymity social desirability sensitive information low incidence rate respondent control
question
requirements for inferring a CAUSAL RELATIONSHIP between 2 variables
answer
concomitant variation time order of occurrence of variables elimination of other possible causal factors
question
Concomitant variation
answer
two variables occur together, the extent to which a cause and an effect occur together or vary together in the way predicted by the hypothesis
question
Time order occurrence of variables
answer
cause has to happy before the effect, or with the effect, cant be afterwards
question
Elimination of other possible causal factors
answer
eliminate as many cases as possible, absence of other possible causal factors - the factor or variable being investigated should be the only possible causal explanation
question
Internal validity
answer
whether the manipulation of the independent variables or treatments caused the observed effects on dependent variables control of EXTRANEOUS VARIABLES is a necessary condition for establishing internal validity
question
External validity
answer
whether the cause and effect relationships found in the experiment can be generalized are findings generalizable to the outside population to what specific populations, settings, time, independent/dependent variables can the results be projected?
question
Steps to implement a post-test only group design
answer
Sample of respondents selected at random, sample is split randomly with half of the subject forming the experiment group and the other half form the control group, only respondents in the experiment group would be exposed to the variable, both groups would be tested to see how the variable affected did not affect the experiment group
question
Symbol of post-test only group
answer
EG: R X 01 CG: R 02
question
Primary scales of measurement (INOR)
answer
interval, nominal, ordinal, ratio,
question
Interval
answer
scales that have characteristics of ordinal + equal intervals between points equal distances on the scale represent equal values in the characteristic being measured permits comparison between 2 objects location of zero point is not fixed in statistics you use arithmetic mean, standard deviation, correlation, etc. used to measure attitudes, motivations, emotions
question
Nominal
answer
partition data into mutually exclusive and collectively exhaustive categories numbers are labels/tags identifying and classifying objects numbers don't reflect the amount of the characteristics possessed by the objects statistics is limited based on frequency counts, percentage of objectives in each category used for DEMOGRAPHICS (gender, income, occupation)
question
Ordinal
answer
maintains labeling characteristics of nominal scales and has ability to order data can determine whether an object has more or less of a characteristic than some other object (but not specifically how much more or less) Numbers dont indicate absolute quantities ordinal numbers don't imply equal interval between the numbers Example: measure order of consumer preferences ranking 5 department stores in order of preferences (45 percent of respondents choose Target)
question
Ratio
answer
Have the characteristics of interval + meaningful zero point
question
Difference between nominal and ordinal scale
answer
ordinal scales have the same characteristics of nominal scales BUT have the ability to order data, can determine whether an object has more or less of a characteristic
question
Advantages of a ratio scale over an interval scale?
answer
Ratio scales - all statistical techniques can be applied, has an absolute zero point Can measure sales, costs, market share and number of customers on a ratio scale Knowing scale type informs us what stat analysis to perform in data analysis have characteristics of interval + absolute zero point
question
Likert scale
answer
respondents identify degree of agreement of disagreement with a series of statements respondents readily understand how to use the scale (mail, phone, personal interview, online survey) takes longer to complete because respondents have to read each statement analysis can be conducted on an item by item basis or total score reverse scores are needed for negative statements
question
Example of Likert Scale
answer
"Sarah sells a high quality product" Indicate your degree of agreement or disagreement Strongly disagree --> strongly agree
question
True score model
answer
true score theory maintains that every measurement in an additive composite of two components: true ability of the respondent on that measure and random error
question
What is reliability?
answer
Is the measure consistent? If we measured personality today and tomorrow how close would the two results be? It is necessary but not sufficient condition for validity Example of a type of reliability: measurement reliability
question
What is validity?
answer
Are we measuring what we think were measuring? Do our personality scale actually measure personality?
question
Different types of validity
answer
face, content, criterion, construct
question
Face validity
answer
degree to which a measurement seems to measure what it is supposed to measure on its face, do the items seem to represent the construct
question
Example of face validity
answer
dressing up for a job interview
question
Content validity
answer
How well the content of a scale represents the measurement task efforts including literature review, focus groups, expert panels to determine content validity
question
Example of content validity
answer
of a math professor: educational degree, research experience, published papers, teaching experiences
question
Criterion validity
answer
Reflects whether a scale performs as expected in relation to other variables selected as meaningful criteria
question
Example:
answer
criterion of a math professor: lets both take a college level math test, person who is a real math professor is more likely to perform better than the person who is not
question
Construct validity
answer
extent to what the researcher was trying to measure was actually measured how do your results relate to the theory?
question
What is the relationship between validity and reliability?
answer
if the measure is perfectly valid than it is also perfectly reliable. if there is no case of random or systematic error if the measure is unreliable it cant be perfectly valid, since at minimum there is random error present if a measure is perfectly reliable it may or may not be perfectly valid because systematic may still be present
question
How can the model of administration affect questionnaire design?
answer
interviewer administered - can be lengthy and complex - visual aids can be incorporated in a face to face interview self administered - questions must be short and simple - instructions must be thorough computer assisted - can incorporate multi media stimuli - complex skip patterns - customization - randomization of questions
question
Reasons respondents are unable to answer the question being asked?
answer
are not informed on the topic of interest market researchers should consider using filter questions or an "i dont know" option many common experiences are difficult to remember, consumers dramatically overestimate usage when estimating consumption levels unable to articulate certain types of respondents (give aids like descriptions to help them)
question
Reasons respondents are unwilling to answer specific questions?
answer
effort required of the respondent - most respondents are unwilling to devote a lot of effort to provide information legitimate purpose - respondents object to questions that do not seem to service a legit purpose sensitive information - unwilling to disclose accurately sensitive information because this may cause embarrassent or threaten their self image
question
What conditions would a sample be preferable to a census?
answer
if you want selected members of the population to be sampled a properly designed sample provides reliable information to infer about the population without actually having to ask everyone (unlike a census)
question
What are incidence rates?
answer
number of respondents that qualify for a study based on certain screening criteria vary depending on who we are targeting to study
question
How do probability sampling techniques differ from non probability techniques?
answer
Probability sampling = conclusive research, high variability in the population, favorable statistical considerations Non-probability sampling - sample is not representative of any definable target population, generalizations cannot be made, statistical inference from sample to the population of interest is problematic, low cost, easy implementation
question
What is the least expensive and least time consuming of all sampling techniques? Limitations of this technique?
answer
Non probability sampling - low cost and easy implementations Limitations - chance of being selected into the sample isnt precisely known, generalizations cannot be made, statistical inference from sample to the population of interest is problematic
question
Stratified sampling
answer
Two step process 1. divide the original population into mutually exclusive and exhaustive subsets 2. elements of each stratum are then randomly selected can acquire information about the whole population and individual strata can lead to increased precision information necessary to properly stratify the sample isnt usually available
question
Describe the cluster sampling procedure
answer
three step process: 1. Divide the target population into mutually exclusive and collectively exhaustive clusters (neighborhoods) 2. select a random sample of clusters based on probability sampling 3. for each selected cluster, either include all elements or a random sample of elements
question
Key distinction between cluster and stratified sampling
answer
Cluster is a sample of clusters chosen and the objective is to increase sampling efficiency to decrease costs Stratified sampling are all subpopulations are used, and objective is to increase precision
