Simple Random Sampling
-probability
- elements are drawn at random
- probability of being selected is known
Systematic Sampling
-probability
-a random starting point and then selecting every ith element in succession
-useful if it follows a certain order
Cluster Sampling
-probability
1. divide the population into mutually exclusive and collectively exhaustive stratas = clusters
2. select a sample of clusters at random
Stratified Sampling
- probability
- 2 stage technique
1. partition the population into subpopulations
2. select elements from each strata
Exploratory Research
-qualitative
-secondary data
-direct or indirect
Descriptive Research
- quantitative
-conclusive research with the objective of describing something
-survey
Causal Research
- quantitative
-when the occurrence of x increase the probability of the occurrence of y
Deductive
- looks at the problem logically
- top down approach
- quantitative
- general to specific
- general theory to formualte hypothesis to test hypothesis
Abductive
-combines deductive and inductive
-starts with an observation of a surprising fact and attempts to explain how it came about
Inductive
-bottom up approach
- requires secondary data
- qualitative
- specific to general
- data collection to identify patterns to develop theory
5 major research philosophies
- Positivism
- Critical Realism
- Interpretivism
- Post-modernism
- Pragmatism
Direct Exploratory data
-focus groups or depth interviews
-purpose of the research is disclosed before or it is obvious
Indirect Exploratory data
-projective techniques
- purpose of the research is deliberately disclosed
management decision problem
- the decision that needs to be made
-action centered
marketing research problem
the information that we need to work out why the problem is happening
verbal model
provide a written representation of the relationship between the variables
