Business Research
a series of well thought out activities and carefully executed data analysis that help a manager avoid, solve or minimize a problem
Applied Research
to solve a current problem that demands a timely solution. Applies to a specific company, within firms or research agencies
Fundamental Research
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)
Internal Research Benefits
More chance of being accepted, Less time needed to understand the structure of the organization, Less costly
Internal Research Disadvantages
Might be stereotyped, not perceived as experts by the staff, less objective findings
External Research Benefits
Has experience in working with different types of organizations, more knowledge
External Research Disadvantages
High cost and time, might not be accepted by Staff
The Hallmarks of Good Research
Purposiveness, Rigor, Objectivity, Parsimony, Replicability, Generalizability
Purposiveness
A definite aim or purpose, knowing the ‘‘why’’ of your research
Rigor
Ensuring a good theoretical base and a good methodological design adds rigor to a purposive study (implies carefulness)
Objectivity
Drawing conclusions based on facts rather than on subjective ideas
Parsimony
Shaving away unnecessary details, explaining a lot with a little
Replicability
Finding the same results if the research is repeated in similar circumstances
Generalizability
Being able to apply the research findings in a wide variety of different settings
Deductive Research
Theory to data, testing theory
Inductive Research
data to theory, building theory
Seven-step Deductive Research Process
- Define the Business problem.
- Formulate the problem statement.
- Develop theoretical framework
- Choose a research design
- Collect data
- Analyze data
- Write-up
Seven-step Inductive Research Process
- Define the business problem
- Formulate the problem statement.
- Provide a conceptual background
- Choose a research design
- Collect data
- Analyze data
- Develop theory
Primary data
Information that the researcher gathers first hand through instruments such as surveys
Secondary data
Data that already exists and doesn’t have to be gathered by the researcher
Business Problem
Gap between actual and desired situation (state)
What makes a good business problem?
Feasibility and relevance
Feasibility
Is it doable?
- Is the problem demarcated? (Make smaller if it is too big)
- Can the problem be expressed in variables?
- Are you able to gather the required data?
Relevance
Is it worthwhile?
Managerial relevance
Who benefits from having my problem solved?
Academic relevance
Has the problem not already been solved in prior research?
Completely new topic (academic relevance)
No research available at all, although the topic is important
New context (academic relevance)
Prior research is available but not in the same context
Integrate scattered research (academic relevance)
e.g., different studies have focused on different IVs/moderators; consequently, their relative importance is not clear
Reconcile contradictory research (academic relevance)
Solve the contradictions through introducing one or more moderators
A good problem statement is….
- Formulated in terms of variables and relations
- Open-ended question
- Stated clearly/ unambiguously
- Managerially and academically relevant
Good research questions…
- Should collectively address the problem statement; one problem statement is translated into multiple research questions
- First theoretical, then practical research questions
- Stated clearly/ unambiguously
Theoretical Research questions
Context questions, conceptualization questions, relationship questions
Practical Research Questions
Relationship Questions, implication Questions
Relationship Questions (Practical)
To what extent does X affect Y?
What is the (relative) magnitude of the relations?
Implication Questions (Practical)
How can practitioners implement your results?
Open question
3 Types of Research Questions
- Exploratory research question
- Descriptive research question
- Causal research question
Exploratory Research Questions
Often relies on qualitative approaches to data gathering (not much is known)
Descriptive Research Questions
Obtain data that describes the topic of interest
Causal Research Questions
Studies whether or not one variable causes another variable to change
A theoretical framework consists of…
Variable definitions
Conceptual model
Hypotheses
Variables
Anything that can take on varying values
Dependent Variable
The phenomena that you are trying to understand (measuring variable)
Independent Variable
Influences the dependent variable in a positive or negative way (manipulated variable)
Mediating variable
A variable that explains the mechanisms at work between X and Y
Full mediation
X only has effect on Y through the mediating variable
Partial mediation
X has an indirect effect on Y through the mediating variable, but also has a direct effect on Y
Moderating variable
A variable that alters the strength and sometimes even the direction of the relationship between X and Y
Quasi moderation
Moderating variable moderates the relationship between X and Y, but it also has a direct effect on Y
Pure moderation
Moderating variable moderates the relationship between X and Y, but it has no direct effect on Y
The 4 conditions for causality (to establish a change is n the IV causes a change in the DV)
- X and Y co-occur (covary)
- A logical explanation for the effect of X on Y is needed
- X proceeds Y in time
- No other cause (Z) explains the co-occurrence of X and Y
Omitted variable bias
Lack of important variables in the model
Hypotheses
A tentative statement about the coherence between two or more variables
Directional (one-sided) hypotheses
Direction of the relationship is indicated. Terms such as positive, negative, more than, less than are used
Unidirectional (two-sided) hypotheses
They postulate a relationship or difference but offer no indication of the direction
Null hypotheses
Expresses NO relationship or difference between groups and is set up to be rejected (almost never presented in research reports)
Alternate hypotheses
Express their relationship or difference between groups; research hypothesis
Negative case method
To test the hypothesis, the researcher should look for data to refute it. When you find data that does not support the hypothesis, the theory needs revision.
Research Design / Plan
Plan for collection, measurement, and analysis of data
Causal Research: Experiment
A data collection method in which one or more IV’s are manipulated to measure the effect of this manipulation on the DV
Critical research design decisions
- Choosing between deductive research strategies
- Choosing between statistical techniques
- Choosing between sampling designs
Causal Research Experiment: Lab experiments
- Explore cause and effect relationship in artificial environment
- One or more IV’s manipulated after which the effect on the DV is measured
- High degree of control by researcher
Causal Research Experiment: Field experiments
- An experiment is carried out in the natural environment (work/life goes on as usual)
- Manipulation/ interference possible
Deductive research strategies
Lab experiments, field experiments
Correlation Research
Descriptive Research
Archival Research (Correlation research)
- Research based on data that already exists
- External: data gathered by sources outside of the firm
- Internal: existing company data
Survey Research (Correlation research)
Research based on questionnaire to which respondents record their answers, typically with closely defined alternatives
Contrived Settings
Artificial environment (lab experiment)
Non-contrived settings
Natural environment (field study)
Unit of Analysis
Individual, Dyad (two person interaction), Group, Organization, Culture
What determines the unit of analysis?
The research question
Cross sectional (time horizon)
Data gathered just once, one shot studies
Longitudinal (time horizon)
Study phenomena at more than one point in time (more time and effort, more expensive)
Mixed method research
Research question cannot be answered by qualitative or quantitative approach alone
Is more data better?
Raw data means nothing without the proper tools to analyse or interpret them
Descriptive statistics
Methods of summarizing the data in an informative way
Types of measures for descriptive statistics
Measures of central tendency: mean, mode, median
Measures of dispersion: range, standard deviation, variance and interquartile range
Inferential statistics
Methods to draw conclusions
Methods to draw conclusions (inferential stats)
Mean difference test, chi square test, ANOVA, regression analysis, logit analysis etc.
4 Types of Measurement Scales
- Nominal
- Ordinal
- Interval
- Ratio
Nominal (Types of measurement scales)
No logical order (ethnicity, social security number, gender)
Ordinal (Types of measurement Scales)
Ranked and ordered (not only categorizes but also rank order them in a meaningful way) (clothing sizes, ranking)
Interval (Types of measurement scales)
Meaningful differences between values, but no natural zero point (the difference between any two values on the scale is identical to the difference between any other two neighbouring values on the scale is identical to the difference between any other two neighbouring values on the scale (e.g., thermometer, time on a 12-h clock))
Ratio (Types of measurement scales)
Meaningful differences and ratios between values due to a natural zero point i.e., income, weight, money, blood pressure etc.
