Week 4 REVIEW
2
Observation and Experimentation
3
OBSERVATION The systematic process of witnessing and recording behaviour – of people, objects and events
4
Seven Types of Observable Phenomena:
Physical actions Verbal behaviour Expressive behaviour Spatial relations Time patterns Physical objects Pictorial records
5
Direct Observation Error
Errors can occur due to: Observer bias Incomplete reporting Interpretation errors
6
Physical Trace Evidence:
A visible mark of some past event e.g. University of Arizona garbage Project (see Zikmund)
7
Content Analysis: Systematic observation and quantitative description of content of communications
8
Mechanical Observation Includes:
Television Monitoring (Nielsen PeopleMeter) Website Monitoring (Jupiter Media Metrix) Scanner Research (Universal Product Code) Physical measurement (eye-tracking/voice pitch analysis)
9
Experimentation
10
Experiments Investigate and evaluate causal relationships between variables Differs from other methods in the degree of control
11
Experiments in Marketing include:
Test Marketing Blind testing Extended User Testing Pilot Trials
12
Experiment Design Issues include: Manipulation of Independent Variable
Selection and Measurement of Dependent Variable Selection of Test Units Control of Extraneous Variables
13
SURVEY RESEARCH (re: Zikmund, Chapter 7)
14
Survey Research A method of collecting primary data by communicating with a representative sample of people
15
Based on simple idea: “”… the best way to find out what consumers think is to ask them.” Zikmund
16
Properly conducted Surveys can be:
Quick Inexpensive Efficient Accurate Flexible
17
Problems with Surveys come from:
Nonresponse error Response bias Administrative error
18
Types of Sampling: Personal Interviews Intercepts Telephone interviews Self administered questions Mail questionnaires
19
Attitude Scaling (Zikmund, Chapter 10)
20
Attitude: An enduring disposition to consistently respond in a given matter
21
Three Components of an Attitude:
Affective Cognitive Behavioural
22
Affective : The feelings or emotions toward an object Cognitive : Knowledge and beliefs Behavioural: Predisposition to action
23
Measuring Attitudes Ranking Rating Sorting Choice
24
The Attitude Measuring Process:
Ranking - Rank order preference Rating - Estimates magnitude of a characteristic Sorting - Arrange or classify concepts Choice - Selection of preferred alternative
25
Simple Attitude Scaling:
In its most basic form, attitude scaling requires that an individual agree with a statement or respond to a single question. This type of self-rating scale merely classifies respondents into one of two categories;
26
Method of Summated Ratings: The Likert Scale:
An extremely popular means for measuring attitudes. Respondents indicate their own attitudes by checking how strongly they agree or disagree with statements. Response alternatives: “strongly agree”, “agree”, “uncertain”, “disagree”, and “strongly disagree”.
28
Semantic Differential:
A series of seven-point bipolar rating scales. Bipolar adjectives, such as “good” and “bad”, anchor both ends (or poles) of the scale
