Objective:

Character-istics:

Findings /Results:

Outcome:

To provide insights and understanding.

Information needed is defined only loosely. Research process is flexible and unstructured. Sample is small and non-representative. Analysis of primary data is qualitative.

Tentative.

Generally followed by further exploratory or conclusive research.

To test specific hypotheses and examine relationships.

Information needed is clearly defined. Research process is formal and structured. Sample is large and representative. Data analysis is quantitative.

Conclusive.

Findings used as input into decision making.

Data collection method, response rate, quality & analysis of data, sampling technique & size, questionnaire design, field work.Examine errors in approach,research design, sampling,datacollection & analysis, & reporting.Time lag between collection &publication, frequency of updates.Why were the data collected?

Definition of key variables, units of measurement, categories used, relationships examined.Expertise, credibility, reputation, & trustworthiness of the source.

Data should be reliable, valid, & generalizable to the problem.

Assess accuracy by comparing data from different sources.Census data are updated by syndicated firms.The objective determines the relevance of data.Reconfigure the data to increase their usefulness.

Data should be obtained from an original source.

Type Characteristics Advantages Disadvantages Uses Surveys Surveys conducted

at regular intervals Most flexible way of obtaining data; information on underlying motives

Interviewer errors; respondent errors

Market segmentation, advertising theme selection and advertising effectiveness

Diary Purchase Panels

Households provide specific information regularly over an extended period of time; respondent asked to record specific behaviors as they occur

Recorded purchase behavior can be linked to the demographic / psychographic characteristics

Lack of representativeness; response bias; maturation

Forecasting sales, market share and trends; establishing consumer profiles, brand loyalty and switching; evaluating test markets, advertising, and distribution

Diary Media Panels

Electronic devices automatically recording behavior, supplemented by a diary

Same as diary purchase panel

Same as diary purchase panel

Establishing advertising rates; selecting media program or air time; establishing viewer profiles

Criteria for the Selection of Test MarketsCriteria for the Selection of Test Markets

Test Markets should have the following qualities:

1) Be large enough to produce meaningful projections. They

should contain at least 2% of the potential actual

population. 2) Be representative demographically.

3) Be representative with respect to product

consumption behavior.

4) Be representative with respect to media usage.

5) Be representative with respect to competition.

6) Be relatively isolated in terms of media and physical distribution.

7) Have normal

historical development in the product class 8) Have

marketing research and auditing services available 9) Not

be over-tested
