Workshop 1 - Problem Analysis Flashcards
Reliability
Refers to the degree to which multiple measurements come up with the same results.
Text/re-test reliability
Imagine you take an IQ test, repeat that two weeks later, to what extent do the results agree with each other?
Inter-rater reliability
When two people are assessing something, to what extent do the results agree with each other?
Internal consistency
Imagine you want to assess someone’s mood with three different questions, to what extent do the results agree with each other?
Validity
Refers to the degree to what extent your measurement corresponds to what you want to measure. Can also be called accuracy.
Basic research
Generates a body of knowledge by trying to comprehend how certain problems that occur in organisations can be solved
Applied research
A methodology used to solve a specific problem of an individual group.
Five steps of the research cycle
- Problem analysis
- Research design
- Data collection
- Data Analysis
- Reporting
Problem analysis
- Direct cause
- Problem
- Aim
- Research question
- Hypotheses
Direct cause
Answer the all-important WHY-question
Problem
Elaborate on the characteristics of the problem
Aim
What is the aim of the study? What will the result of this study all you to do/decide that you can’t do/decide now?
Research question
Which overarching question will your research answer? Which sub-questions do you need to answer first to get there?
Hypotheses
Make predictions about the outcomes if you have enough information to do so
Research design
- Operationalise of variables
- Type of research and study
- Population and sampling
- Research method
- Representativeness, biases and quality
Operationalisation
Intended to guard the clarity of your research.
Every concept or term that you used in the problem analysis needs a detailed definition.
Type of research and study
Know what and how
Descriptive studies
Presenting known information
Exploratory studies
Trying to find new information
Examinatory studies
Checking if your hypotheses are true
Quantitative research
Outcome is in numbers
Qualitative research
Any type of study that aims to acquire information that is not numerical.
Population
The focus group of your research
Sample
A smaller group chosen from the population
Research method
- Which research tool
- Which instrument are you going to use?
- What procedure will you follow?
Representativeness
Whether your sample is sufficiently representative of this population
Quality of the measurements
Check the quality of your measurements. Assure that no bias took place. (Bias - the degree to which the objectivity of measurements is affected by noise.
