a)
Exploratory studies: Exploratory have loose structures with the objective of discovering future research tasks. The immediate purpose of exploration is usually to develop hypotheses or questions for further research.
Formal studies: The formal study continues the exploratory study. It begins with a hypothesis or research question and involves precise procedures and data source specifications. The goal of a formal research design is to test the hypotheses or answer the research questions posed. Both of these definitions are taken from the textbook.
b)
Experiments: In experiments the researcher can manipulate or control the variables or at least one of the variables.
Ex post facto research design: Here does the researcher have no control over the variables. The researcher can only report what he sees or what is happening.
c)
Descriptive: This kind of study investigate the questions who, what, where, when, or how much.
Causal studies: In the causal studies on the other hand the researcher try to explain the relationship among or between variables. The researcher also looks at how the different variables affect each other.
a)
Causality is more likely to happen if you use the inductive method because this method is based on few observations where as the deductive method is based on a general theory. Therefore the deductive method is better to avoid causality.
b)
Because you don’t have tested theory or rule to base your research on when you use induction.
c)
Here is an example of correlation, which does not imply causation: Height is correlated to income. You might find studies, which imply that tall people earn more money than not so tall people, but does this makes it thru? No, you can say that there are any causation between height and income.
a)
Stimulus response: If the price on beer increases I would substitute it for wine.
Property-disposition: When I get older I will probably earn more money and would start saving more of
