TESTE DEIN WISSEN
What is population and how to be chosen? What is the advantage of correctly chosen population?
Lösung anzeigen
TESTE DEIN WISSEN
Population - set of units, from which sample will be drawn. Deliberately chosen population is usual, random - not. Correctly chosen population = determined limits of generalizability + elimination of irrelevant differences

What is the 3rd step of case study about?
Lösung anzeigen
TESTE DEIN WISSEN
Combination of different methods of data collection helps to enable triangulation(compensation of weakness through strength) and provides stronger support. CS uses qualit-understand causal rel-p,derive conclusion/quanti-not led away/both. + Advantages of teamwork

TESTE DEIN WISSEN
Why use Statistic Hypotheses?
Lösung anzeigen
TESTE DEIN WISSEN
Because the economic phenomena is nondeterministic(only valid in majority cases) and it is not possible to conclude from one single contradiction, statistical hyp is needed.

TESTE DEIN WISSEN
What is falsificator?
Lösung anzeigen
TESTE DEIN WISSEN
A possible data combination which leads to the rejection of a hypothesis.

TESTE DEIN WISSEN
3 Types of statistical hypothesis
Lösung anzeigen
TESTE DEIN WISSEN
1) Association H. (A and B are related) 2) Causality(ursache) H.(A acts causally upon B) 3) Difference H. (A is different from B)
