Transcript

  • 1. Advantages of Survey Methods
    • Ability to accommodate large samples sizes at relatively low cost.
    • Ease of administration
    • They collect quantitative data ripe for advanced statistical analysis.
    • Ability to tap into factors or concepts that are not directly observable
  • 2. Disadvantages of Survey Methods
    • Possibility of systematic error increases
    • Limited use of probing questions
    • It can be difficult to know whether the selected respondents are being truthful
    • The statistical techniques selected may introduce very subtle and insidious levels of subjectivity
  • 3. Types of surveys interview
    • Person Administered
    • In home interview
    • Executive interview
    • Mall intercepted interview
    • Purchase interview
    • Telephone Administered
    • Telephone interview
    • Compute red assisted Telephone interview (answers by pushing buttons on their phones)
  • 4. Types of surveys interview
    • Self Administered
    • Mail panel interview
    • Drop off survey
    • Mail survey
    • Computer assisted on line
    • Fax survey
    • E Mail survey
    • Internet surveys
  • 5. Factors for selecting the appropriate survey method
    • Situational Characteristics
    • Budgets
    • Competition time frame
    • Quality requirement of the data
    • Task Characteristics
    • Difficulty of the task
    • Stimuli needed to elicit a response
    • Amount of information needed
    • Research topic sensitivity
  • 6. Factors for selecting the appropriate survey method
    • Respondent Characteristics
    • Diversity
    • Incidence rate
    • Degree of survey participation
  • 7. Overview of the types of errors in survey research methods
    • Non response errors
    • Response errors
    • Measurements and designs errors sources
    • Scaling Measurements error
    • Survey instruments designs error
    • Data analysis error
    • Misinterpretation error
  • 8. Overview of the types of errors in survey research methods
    • Administrative error source
    • Data processing error
    • Interview error
    • Sample design error
    • Non sampling error
    • Respondent error
    • Researcher ’s measurements design error
    • Faulty problem definitions
    • Researchers administration problems
  • 9. CONDITIONS FOR USING OBSERVATIONAL TECHNIQUES
    • Information : Currents behavior patterns.
    • Type of data : Necessary data must be observable
    • Time frame: Data patterns must meet repetitiveness frequency, and predictability factors in a prespecified time frame
    • Settings: behavior must be observable in some type of public or laboratory setting
  • 10. CHARACTERISTICS OF OBSERVATION RESEARCH METHODS
    • Directness of observation: The degree to which the researcher or trained observer actually observes the behavior or events as it occurs
    • Subjects awareness of being observed
    • Structuredness of observation . The degree to which the behavior activities or events to be observed are specifically known to the researcher prior to doing the observations
    • Type of observing Mechanisms How the behavior activities or events will be observed and recorded
  • 11. TECHNIQUES USED IN MEASURING PHYSIOLOGICAL ACTIONS AND REACTIONS
    • The Voice Pitch analyzer
    • The pulpilometer
    • Eye tracking monitor
    • The Psychogalvanometer
  • 12. SELECTING THE APPROPRIATE OBSERVATION METHOD
    • The researcher must answer the following questions
    • What types of behavior are pertinent to the defined researcher problem?
    • How simple or complex are the behaviors
    • How much detail if the behavior is needed to be recorded?
    • What is the most appropriate setting (natural or contrived) for the behavior
  • 13.
    • How complex is the required public setting?
    • Is It available for observing the specified behavior or event?
    • To what extent are the desired behavior repetitious and frequently observed?
    • What degree of directness and structured should be associated with observing the behavior or events?
    • How aware should the subject be that they and their behavior should be observed
    • Are the observable events complex enough to require the use of a mechanical device for observing the behavior
  • 14. Types pf variables used in experimental Designs
    • Independent variable The independent variable is assumed to the causal factor of a functional relation ship with a dependent variable
    • Dependent variable a singular observable attribute or element that is the measured outcome or effect change on a specified test subject hat is derived from manipulating the independent variable measured -Control variable
    • Control Variable Variables that the researcher controls so that they don’ t affect the functional relationship between the impendent and dependent variable of the experiment
    • Extraneous variable Uncontrollable variables that should average out over a series of experiment, if not accounted for they can have a confounding impact on the dependent variable measures
  • 15. Types of experimental Research Designs
    • X = The exposure of an independent variable ( treatment manipulation) to a group of test subject for which the effects are to be determined.
    • O = the process of observation or measurement of the dependent variable (effect outcome) on the test subjects.
    • R = the random assignment of the test subjects to separate treatment groups
    • EG = The experimental group of a test subjects
    • CG = The control Group of a test subject
  • 16. Pre experimental designs
    • One shot study
    • When the researcher wishes to observe or measure al customer reactions to a product display in a single store
    • One group Pre test Post test
    • It is taken a pretest criterion measure of ad recall, product environment , media habits or purchase history the a experimental independent treatment measure is delivered( TV commercial) followed by a post test measure of the dependent variable
    • Static group comparison
    • Many studies look at a two sore settings of heavy users versus light users when comparing new produtcs sales
  • 17. True experiemntal desings
