Classification of Qualitative Research Procedures
Ü True purpose of the study is not disguised
Ü True purpose of the study is disguised
Ü A moderator leads a interactive discussion on the research problem with a small group of respondents.
Ü The value of the technique lies in the unexpected findings often obtained from a free-flowing group discussion.
Table 4.2 Characteristics of Focus Groups
The success of a focus group session depend heavily on the moderators and his/her communication, interpersonal, probing, observation and interpretative skills. The key characteristics of good qualitative research are:
Ü Kindness with firmness
Ü Exhibit incomplete understanding
Variation in Focus groups
Ü Two-way focus groups
Ü Dual-moderator group
Ü Duelling-moderator group
Ü Respondent moderator group
Ü Client participant group
Ü Mini groups
Ü Telesession group
Ü On-line focus group
Advantages of Focus groups
Ü Scientific scrutiny
Disadvantages of Focus groups
Application of Focus groups
Ü Understanding consumers’ perceptions, preferences and behaviour concerning a product category
Ü Obtaining impressions of new product concepts
Ü Generating new ideas about older products
Ü Developing creative concepts and copy material for advertisements
Ü Securing price impressions
Ü Obtaining preliminary consumer reaction to specific marketing programs
Case: Focus Group at GM
Ü General Motors used focus groups and survey research to help develop the coupe. They held 20 focus groups across the country to determine what features customers wanted in a car. The focus groups told GM they wanted a stylish car, legitimate back seat, good fuel economy acceleration and power.
Ü Based on these results, engineers created clay models of the car and mock-ups of the interior. These were shown to another set of focus groups of target buyers. These respondents did not like the oversized bumpers and the severe slope of the hood, but liked the four-disc brakes and independent suspension.
Ü An unstructured, direct, personal interview in which a single respondent respondent is probed by a highly skilled interviewer to uncover underlying motivations, beliefs, attitudes and feelings
Characteristics of In-depth Interviews
Ü Unstructured, direct, personal interview in which a single respondent is probed by a highly skilled interviewer to uncover underlying motivations, beliefs, attitudes and feelings on a topic
Ü 30 minutes to 1 hour in duration
Ü Probing is of critical importance in obtaining meaningful responses and uncovering hidden issues
Ü Avoid appearing superior and put the respondent at ease
Ü Be detached and objective, yet personable
Ü Ask questions in an informative manner
Ü Not accept brief ‘yes’ or ‘no’ answers
Ü Probe the respondent
Advantages of In-depth Interviews
Ü Uncover greater depth of insights
Ü Large amount of detailed data can be obtained from the respondent
Ü Attribute the responses directly to the respondent
Ü Free exchange of information
Disadvantages of In-depth Interviews
Ü Skilled interviewers required
Ü Lack of structure tends to lead to lack of generalisability, reliability, and the ability to distinguish small differences
Ü Reduced accuracy possibly due to potential biases from interviewer-respondent artefacts, respondent bias, or interviewer errors
Ü Data obtained is difficult to analyse and interpret
Ü Costly and time consuming
Applications of In-depth Interviews
Ü Where detailed probing of the respondent is required
Ü Discussion of confidential, sensitive, or embarrassing topics
Ü Situations where strong social norms exist and the respondent may be easily swayed by group responses
Ü Detailed understanding of complicated behaviour
Ü Interviews with industry people
Ü Interviews with competitors, who are unlikely to reveal the information in a group setting
Ü Situations where the product consumption experience is sensory in nature, affecting mood states and emotions
Ü An unstructured, indirect form of questioning that encourages respondents to project their underlying motivations, beliefs, attitudes or feelings regarding the issue of concern
Ü An individual is presented with a stimulus and asked to respond with the first thing that comes to mind
Ü Respondents are likely to reveal their inner feelings about the topic of interest
Ü Responses are calculated by:
Ü The frequency of a given response
Ü The amount of time that elapses before a response is given
Ü The number of respondent who do not respond at all to a test word within a reasonable time period
Ü Respondents are asked to complete a sentence or story.
Completion Techniques cont.
Ü Respondents are given part of a story – enough to direct attention to a particular topic not to hint at the ending
A woman is organising a surprise party for her husband. She realises there is so much to organise – the food, decorations and entertainment and doesn’t know where to start. What should she do?
Ü Picture response techniques
Ü Cartoon tests
Ü Role playing
Respondents asked to play the role or assume the behaviour of someone else
Ü Third person technique
Respondent is asked to relate the beliefs and attitudes of a third person
eg. Do you think your friend would shop at Best and Less?
Advantages of Projective Techniques
Ü Elicit responses that respondents would be unwilling or unable to give if they knew the purpose of the study
Ü Useful when issues are personal, sensitive or subject to strong social norms
Ü When underlying motivations, beliefs are operating at the subconscious level
Disadvantages of Projective Techniques
Ü Highly trained interviewers are needed
Ü Risk of interviewer bias
Usefulness of Projective Techniques
Ü Useful when the required information cannot be accurately obtained by direct methods
Ü Used for exploratory research to gain initial insights and understanding
Ü Used to test brand names
Ü Measure attitudes about particular products, brands, packages and advertising
