Secondary Data

Secondary versus Primary data

 Secondary data is data collected for some purpose other than the

present research purpose

– all previously gathered material



 Primary data is data collected to address a specific research purpose, ie,

data required that has not previously been gathered

Advantages of secondary data

 Access – quick & easy to obtain

 Affordable – mostly free; or at minimal cost

 Availability – many sources – electronic availability

 Retrospective – allows researchers to go back in time; enables prediction or forecasting of future

events

 Only available access – tourism data on International visitor arrivals

 Quality – data sources produced by Govts meet high research standards; journals – articles reviewed

 Ability to enhance primary data – base to study

Disadvantages of secondary data

 Relevance & accuracy – as data has been collected for purposes other than the specific research problem,

usefulness may be limited.



 Measurement units in secondary data may not match the researcher‟s needs – different income level

groupings or measured in different ways – household or per capita income



 Recency of the data – too old to

be of value

 Not easy to locate

 May be an incomplete data set

 Lack of information needed to

assess the credibility of the data

(refer to section on evaluating secondary data)



Evaluation of the data’s validity

 Methodology used to collect data – critically examine sample design, response rate,

questionnaire design & admin, field work procedures, data analysis techniques & reporting

 Error – accuracy of data – errors in each stage of the research process

 Currency – when the data was collected

 Objectivity – purpose for which the data was collected

 Nature – the content of the data – how key variables are defined; units of measurement;

categories used etc – how consistent are they with researcher‟s needs

 Dependability of the data – examine the expertise, credibility, reputation and trustworthiness of

the source.

Note: read further about these areas from the handout - Malhotra

Exploratory research design

 What is it?

– Type of research design that has as its primary objective the provision of insights

into and comprehension of the problem situation confronting the researcher.

– flexible

– usually unstructured

– usually qualitative

– primary data



Purpose

 Diagnosing problems

– little prior knowledge

– insights needed into nature of the problem

– lack of previous research/information



 Screening alternatives

 Define terms and concepts/constructs

 Isolate key variables and relationships

 Discovering new ideas

 Establishing priorities for further research

 To develop hypotheses

Qualitative vs Quantitative Research

Strengths of qualitative research

 generate insights

 clarifies problems

 can be quick

 comparatively inexpensive

 more depth/richness

 small number of respondents

Limitations of qualitative research

 tends to be qualitative

 not a replacement for “conclusive” research – ie descriptive or causal

 interpretation typically subjective

 results susceptible to misuse

Common Exploratory Techniques

 Focus Groups

 Individual (Depth) Interviews

 Projective Techniques

 Observation

 Panel

 Delphi

 Case Studies

Focus Groups

 is an type of interview conducted by a trained moderator (facilitator), in

an unstructured/ semi structured free flowing manner, with a small group

of participants

 information is collected through group interaction on a specific topic



 IQCA best practice guidelines – participants restricted to once in any 6 month period





Characteristics of Focus Group

 Group size 8 (6-10)

 group composition homogeneous (but with sufficient variation)

consider objective of focus group

 site selection consider group

 physical setting relaxed, informal

 time/ length 1-2 hours

 number of groups at least 2

 recording audiocassette/video

 sampling similar to population

 require a moderator(role) & assistant moderator(role)

 payment varies by location





Focus Groups

 Common Uses

– background knowledge

– generate new product/service ideas; impressions

– consumer vocabulary

– reveal consumers needs, motives, perceptions, preferences attitudes and behaviours concerning a

product/service

– advertising and communication research –to generate creative concepts & copy material

– price impressions

– reactions to a preliminary marketing program

– to understand findings from quantitative studies





Focus Groups

 Advantage

– synergism – group produce a wider range of information, insights & ideas than only one person

– stimulating – group discussion generates ideas & excitement that develops in the discussion –

snowball of ideas

– spontaneity – as participants don‟t answer specific questions, the discussion generates a more

accurate idea of their views

– security – when participants‟ feelings are similar they are more comfortable to express their ideas

& feeling on topic

– observation – allows clients to observe the group

– works well with participants that don‟t respond to structured questions – children; or hard to

interview - professionals

Focus Groups

 Disadvantages

– moderation – focus groups are difficult to moderate & quality of results depends heavily on the skills of the

moderator

– domination by individuals with strong personalities

– messy – data unstructured & difficult to interpret

– misjudge – susceptible to moderator & client bias; interpretation is subjective

– misrepresentation – not representative of the population & thus not be used as the sole basis for decision

making

– getting appropriate participants

– cost-per-participant is high – recruitment, incentives, moderator, facilities, time of research team

Planning a Focus Groups

 clearly state the research problem

 clearly & concisely specify objectives

 develop interview questions from objectives - open ended (have sub-questions to probe further)

 focus group participants - identify target population; write screening questionnaire to screen potential participants

– product knowledge; demographics; usage behaviour etc

 decision on number of focus groups & size of focus groups

 recruit participants – phone & follow up letter to confirm

 arrange facilities & refreshments

 incentives

 moderator‟s guide – include ground rules for session & questions; open with a more general question, body ,

ending questions

Planning a Focus Groups cont

 Arrive at session – greet participants & make them comfortable; name cards – person & table; on

arrival refreshments & time to socialise, create friendly, warm environment. Moderator should observe

group members interact & identify dominant members etc.

 Begin session – ground rules –thank participants for coming; purpose of session; only one person

speak at a time; use of audio/video equipment, one way mirror – explain use etc

 Opening part of session is to engage participants – ie get them to introduce themselves & few short

remarks

 First main question – more general question that will focus all participants on the research area.

 Body - 5-8 questions with probing sub-questions

 Conclusion –sum up; ask for further comments; thank participants and let them know how they have

contributed

Planning a Focus Groups cont

 Debriefing after session with researcher & client if available – chance to

compare, gain further insights and feed into next focus group

 Review tapes, analysis and interpret data – focus on words; frequency of

comments; intensity of comments; context & build the big picture from the

data points.

 Formal report & presentation to client

Variations in focus groups

 TeleSession – session by phone using the conference call technique

 FocusVison – teleconferencing

 On-line focus groups – chat room environment

Activity

 Video: Walker Information

 Trip to focus room

Depth Interviews

When to use

 Detailed probing of respondent on a topic

 Discussion of confidential, sensitive or embarrassing topics

 Strong social norms exist and thus respondent would be swayed by group response

 Detailed understanding of complicated behaviour

 Interviews with professional people

 Interviews with competitors – unlikely to reveal information in a group

 Situation where product consumption experience is sensory in nature affecting moods & emotions –

perfumes, bath soap







Depth Interviews cont

 purpose of the interview will direct the development of the interview protocol

– a detail guide to the interview

 unstructured interview -rough outline of the questions - need to be flexible

 structured interview - more structured interview protocol

 Advantage : provides „rich‟ data; extensive probing

 Disadvantage: same as focus group



Interviewer’s role

 Avoid appearing superior & put the interviewee at ease

 Be detached & objective, yet personable

 Ask questions in an informative manner

 Not to accept brief „yes‟ or „no‟ answers

 Use probes & prompts to elicit further information

 Listening is very important

Types of interviews

 Face-to-face

 Telephone

 Computer assisted interviewing

– CATI – computer assisted telephone interviewing

– CAPI – computer assisted personal interviewing

Indepth Interview Guidelines & Etiquette (similar for focus

group)

 Arrange appointment to suit interviewee

 Check you have all interview material working & organised

 Always arrive on time

 Be flexible

 Consider your overall appearance – consider the context & dress to suit

 Be aware of cultural protocol & codes of conduct

 Remember the ethical rights of the interviewee & and check they understand their rights

 Introduce yourself on arrival

 Describe the purpose of the meeting & say why they were selected

 Ask permission to take notes, audiotape, or videotape session

Indepth Interview Guidelines & Etiquette

 Use the funnel technique

 Don‟t evaluate

 Don‟t interrupt

 Don‟t bias by introducing your own ideas

 Don‟t worry about pauses

 Check your understanding

 Follow up on areas of interest

 Take notes

 Don‟t get distracted

 Read their body language –comfort level etc

 Advise interviewee of midpoint and when reaching the end

 Thank the interviewee

 Arrange a time to have the interviewee check information / comment on transcript



Projective Techniques

 Is an unstructured, indirect form of questioning that encourages respondents to

project their underlying motivations, beliefs, attitudes or feelings regarding the issue

of concern.



 Respondents are asked to interpret the behaviour of others rather than describe their

own behaviour.



 used when respondents unlikely to give a direct answer







Projective Techniques

 techniques

– word association

– sentence completion

– picture interpretation

– role play -third person



 often used in conjunction with other exploratory techniques

Projective Techniques

 Advantages

– sensitive issues canvassed

– uncover information not otherwise available – at unconscious level – motives, beliefs, attitudes



 Disadvantages

– expensive (need skilled interpreters)

– sample bias – those who agree to participate may be considered unusual in some way – to role

play

– requires highly trained interviewers

– analysis & interpretation difficult & subjective

Observation

 Is the recording of behavioural patterns of people, objects and events in a systematic

manner to obtain information about the phenomenon of interest.

 observer does not question

or communicate with the people

being observed



Structure of observation methods

 direct versus indirect (observe behaviour as it occurs; observe the effect or result of the behaviour)



 disguised versus undisguised (subject is unaware of being observed; subject aware such as in a

lab)



 structured versus unstructured (researcher identifies beforehand which behaviours are to be

observed & recorded; no restriction on what will be noted)



 human versus mechanical (observer is a person; observing device – traffic counter, optical scanning

devise, UPC coding with optical scanner; peoplemeter, on-site cameras

Observation

 Strengths

– subjects unaware – capture natural behaviour

– examine interactions & behaviour in real world setting

– no recall error – observe while engaging in act

– cheap (sometimes)

– may be the only way to obtain accurate info – ie children playing ; „mystery shoppers‟ – competition

(refer to the MRSA site - ESOMAR guidelines for mystery shopping

www.mrsa.com.au about mrsa, mrsa code of professional behaviour

– used to supplement & complement other techniques

– sometimes only possible approach





Observation

 Weaknesses

– behaviour only

– cannot determine attitudes, motivations etc

– can be costly and time consuming

– bias – small number of subjects under special circumstances

– subjective interpretation

– slow and expensive

– observer fatigue

– extensive training for observes – time & cost

Other techniques

 panels – longitudinal – qualitative data & quanitative data

 delphi interviews repeated interviews with experts until consensus

 case study



Ethics in data collection

 Confidentiality

 Researcher must not misrepresent the nature of the study to participants – purpose

explained

 Personal information should not be solicited – if needed, collect in highly sensitive

manner

 Never violate the self-esteem and self-respect of participants

 Informed consent – do not force subject to participate

 Nonparticipant observers should be unintrusive







Ethics in data collection cont

 Participants should not be exposed to physical or mental harm

 Absolutely no misrepresentation or distortion in reporting of data

collected during study

 Participant once agreeing should cooperate fully

 Participant has an obligation to be truthful & honest in the responses

Reporting exploratory research

 Techniques used should be described & justified

– Any deviations; how techniques will assist providing information to meet research problem

 Selection of participants described & profile of participants ( reader can assess

representativeness)

 Report - based on objectives; focus on common themes & use direct quotes from

participants to justify judgements made

Next week

 Descriptive research techniques

– Surveys

Summary

 Exploratory research design & the techniques appropriate for collecting data

 Focus groups – assessed the strengths & weaknesses; when to use; how to plan a

focus group; important role of moderator

 Indepth interviews, when to use, role of interviewer; guidelines & etiquette

 Other techniques - observation; projective; panel; delphi & case study

 Ethics in data collection

 Reporting exploratory research

Tutorial

 Presentation

 Projective techniques – exercise by Hoda

 Focus group role play

– To develop prior to the tutorial a moderator‟s guide for a focus group based on the principles outlined in the

lecture

– To determine how many focus groups (why?) and selection criteria for participants for each focus group

– In class to role play a focus group – moderator; participants & observers

 SPSS – complete work from last week – pie chart & describe graph for a report ;

– Introduction to univariate, bivariate & multivariate analysis;

– Univariate analysis – descriptive statistics – Ch 4 Coakes & Steed & read Cavana pp. 405-13









Focus group exercise

 Management problem

– How effective are the changes made to the USQ Refectory service?

 Research problem

– What are the current customer perceptions and satisfaction level of the new USQ Refectory service?

 Research objective for Focus group

Qbj 1 To determine the most important factors (attributes) when selecting a food service provider at USQ for

lunch time meal

Obj 2 To determine current users perceptions on the Refectory in terms of food quality; food price; food

variety; speed of service; service layout; service providers (add other from Obj 1 to list)

Obj 3 To determine the level of satisfaction by main attributes

Note: Other objectives would be set but for the purpose of this short exercise you are required to deal with the

above 3 objectives.
