2Review – Primary & Secondary MIM Primary Data: Data obtained for the first time and used specifically for the particular problem or issue under studySecondary Data: Data that has already been collected for some purpose other than the current studyIt is most effective for companies to decide what secondary data it will use before collecting primary data. But if you do not get good results, try primarySo how do you collect primary data? See the following
3Survey method for Primary Data A research technique in which information is gathered from people through the use of surveys or questionnaires.Surveyors usually use a sample of the entire target population to get resultsPros:Data can be quantifiedAccurate sample sizeAble to ask many questionsConsLow participation rateFeedback is limited
4Types of SurveysPersonal interview – involves questioning people face-to-face. Often conducted in central locations. Advantage: People are likely to respond. Disadvantage: CostlyFocus group interview- involves eight to twelve people who are brought together to evaluate a product, design, or strategy under the direction of a skilled moderatorTelephone interview – quick, efficient, and relatively inexpensive. Disadvantage: some people are unwilling to participateMail survey – relatively inexpensive way to reach a large audience. Respondents are generally honest and find this type of survey less intrusive. Disadvantage: return rate for mail surveys is less than 5% - 10%.Internet survey – includes wide-open polls, anybody-can-answer polls, invitation-only surveys, password protected research sites, and Internet – based panels.
5Observation method for Primary Data Observation method – a research technique in which the actions of people are watched and recorded either by cameras or observers.Mystery shopper – a researcher who poses as a customerPoint-of-sale research – a research technique that combines natural observation with personal interviews to get people to explain buying behaviorFocus groupsPros:Gauge consumer reactionMonitor group reactionCons:Susceptible to leader’s biasesSmall sample size & expensive
6Experimental method for Primary Data A research technique in which a researcher observes the results of changing one or more marketing variables while keeping certain other variables constant under controlled conditions.Often used to test new package designs, media usage, and new promotions.Pros - Can be performed in actual settingsParticipants not aware of monitoring so natural reactionsCons - Sample is small and hard to controlInterpretation of data may be difficult
7The marketing survey Why? But they must have: Businesses need valid and reliable data to make good decisions.But, marketing researchers need to know how to construct survey instruments that provide the necessary information to assist in the decision-making process.But they must have:Reliability – exists when a research technique produces nearly identical results in repeated trials. Validity- exists when the questions asked measure what was intended to be measured
8The marketing survey Types of questions used in surveys Open-ended questions ask respondents to construct their own response to a question.Example: “How can we serve you better?”Forced-choice questions ask respondents to choose answers from possibilities given. These are the simplest questions to write and the easiest to tabulate.Types of forced-choice questions are as follows:
9The marketing survey Forced-choice questions Yes/No Questions: Only gives two options, should only be used when asking for a response on one issue.Multiple-choice Questions: Gives the respondent several choices, important that the options are made comprehensive enough to include every possible response. Usually includes an “other” option.Rating Scale Questions: Variety of questions used such as very satisfied to very dissatisfied, or excellent to poor.Level of Agreement Questions: Used to assess attitudes or opinions. Commonly used options: strongly agree (SA), agree (A), neutral (N), disagree (D), and strongly disagree (SD).
10The marketing survey Basic guidelines for writing questions: Should be written clearlyShould be as brief as possibleDo not ask leading questions which suggest a correct answerAvoid biasAvoid questions that might cause a respondent to guess at the meaning of your question.Pretest – allows for correction of any misleading questions, directions, or problems
11The marketing survey Formatting Surveys Need excellent visual appearance and design to appeal to respondents.Use dark ink on light paper (Contrast)Use type that is easy to readShade sections for contrastUse arrows to lead the readerUse section headers or numbers on individual survey sectionsNumber the questionsDirections for completion must be clearUse a variety of question types (All answers should not be yes)Group demographic questions about gender, age, ethnic background, and education, etc. at the end of the questionnaire.
