Q

Fundamental Research

A

generate a body of knowledge by trying to understand how certain problems that occur in organizations can be solved. Research done to make a contribution to existing knowledge. (Teaching us something we didn’t know before, mainly done in universities and knowledge institutes)

Q

The sampling process (4 steps)

A
  1. Define the target population
  2. Determine the sampling frame
  3. Determine the sampling design
  4. Determine the sampling size
93
Q

Target population

A

Defining in terms of elements, geographical boundaries and time (Who are you targeting as a sample during this study?)

94
Q

Sampling frame

A

Physical representation of the target population

95
Q

Coverage error

A

When sampling frame does not match the population

96
Q

Sampling design

A

Probability sampling vs. Non-probability sampling

97
Q

Probability sampling

A

Each element of the population has a known chance of being selected as a subject

98
Q

Types of probability sampling (4)

A
  1. Simple random sampling
  2. Systematic sampling
  3. Stratified sampling
  4. Cluster sampling
99
Q

Simple random sampling (probability sampling)

A

Least bias, most generalizable since every element has an equal change of being chosen

100
Q

Systematic sampling (probability sampling)

A

Select random starting point and then pick every I-th element (low generalizability)

101
Q

Stratified sampling (probability sampling)

A

Divide population into groups, then apply SRS within each group

102
Q

Cluster sampling (probability sampling)

A

Divide the population into heterogeneous groups, randomly select a number of groups and select each member within this group

103
Q

Non probability sampling

A

The elements of the population do not have a known chance of being selected as a subject

104
Q

Four types of non-probability sampling

A
  1. Convenience Sampling
  2. Quota Sampling
  3. Judgement Sampling
  4. Snowball Sampling
105
Q

Convenience Sampling (Non-probability sampling)

A

Select subjects who are conveniently available (lowest generalizability)

106
Q

Quota Sampling (Non-probability sampling)

A

Fix a quota for each subgroup, select on the basis of specific criteria

107
Q

Judgement Sampling (Non-probability sampling)

A

Select subjects based on their knowledge/ professional judgement

108
Q

Snowball Sampling (Non-probability sampling)

A

Do you know people who..?

109
Q

A larger sample size leads to….

A

a lower sampling error

110
Q

Rules of thumb for sampling

A
  1. Sample size >75 and <500 is appropriate
  2. Multivariate search: >10x parameters to be estimated
  3. Subsamples: >20-30 per subsample
111
Q

Survey Research

A

Research based on a questionnaire to which respondents record their answers, typically with closely defined alternatives

112
Q

When to use surveys

A
  • Interest in quantitative descriptors

- Want to say something about the population, but you can’t measure the whole population

113
Q

Categories of Questions

A

Open-ended
Closed-ended
Single-item Measures
Multi-item Measures

114
Q

Open-ended Questions

A

Allows respondents to answer a question in any way they choose

115
Q

Closed-ended

A

Asks the respondents to make choices among a set of alternatives

116
Q

Single-item measures

A

When concrete singular object/attribute is used (What is your marital status? What is your profession? NOT ‘’ How diverse is the workforce of your company etc.)

117
Q

Multi-item measures

A

In all other cases

118
Q

Item-response scales

A

Comparative scales, non-comparative scales

119
Q

Comparative scales ( item-response scales)

A
  1. Paired comparison
  2. Contact sum
  3. Rank ordering
120
Q

Paired comparison (comparative scales)

A

Compare pairs of shampoo brands etc.

121
Q

Contact sum (comparative scales)

A

Divide 100 points among the following etc.

122
Q

Rank ordering (comparative scales)

A

Rank brands, rank companies etc.

123
Q

Non-Comparative scales

A

Continuous rating scale
Likert scale
Semantic differentials

124
Q

Continuous rating scale (non-comparative)

A

Rate department score from 0 to 100 etc.

125
Q

Likert scale (non-comparative)

A

Disagree/agree, 5- or 7- point scale

126
Q

Semantic differentials (non-comparative)

A

Good or bad, powerful or weak, modern or old-fashioned

127
Q

Nominal scale measured questions…

A

should be mutually exclusive: only 1 answer applies

should be collectively exhaustive: the answer possibilities cover the entire realm of possible answers

128
Q

Tailor Design Method

A
  1. Pre-notification
  2. Questionnaire (package contains: personalized cover letter, questionnaire, token of appreciation, free return envelope or reply e-mail button)

Q

Validity measures..

A

Provide precedence, but provide sound logic to support that considerable conceptual overlap exists between measurement/proxy and construct

130
Q

Social Desirability Bias

A

Respondents may not always be willing to communicate their true response in case of sensitive issues; to minimize socially desirable responding, use deliberately leading and or/loading questions to make the sensitive normal

131
Q

Reliability of survey measures…

A

For multi-item measures use Cronbach’s Alpha which measure to what extent a set of items are inter-related; when highly inter-related = high reliability

Q

Examining effects across countries (reasons to use archival research)

A

Primary international research is expensive and cumbersome

179
