What are assumptions in a case study?
Paul Vogt defines an assumption as “(a) A statement that is presumed to be true, often only temporarily or for a specific purpose, such as building a theory; (b) The conditions under which statistical techniques yield valid results.”
How do you find assumptions in statistics?
Typical assumptions are:Normality: Data have a normal distribution (or at least is symmetric)Homogeneity of variances: Data from multiple groups have the same variance.Linearity: Data have a linear relationship.Independence: Data are independent.
What are two or three assumptions that are made specific to qualitative research?
researchers explicitly recognize and acknowledge the value-laden nature of the research; research is context-bound; research is based on inductive forms of logic; categories of interest may emerge from informants (internal) or be used to frame the understanding (external);
What is a methodological assumption?
Methodological assumptions consist of the assumptions made by the researcher regarding the methods used in the process of qualitative research (Creswell 2003). The procedures used by the researcher are inductive and are based on the researcher’s own experience in collecting and analyzing data.
What are ontological assumptions?
The Ontological Assumptions It is concerned with “what kind of world we are investigating, with the nature of existence, with the structure of reality as such”. Guba and Lincolin (1989:83) state that the ontological assumptions are those that respond to the question ‘what is there that can be known?

What is ontology used for?
One major advantage of using a domain ontology is its ability to define a semantic model of the data combined with the associated domain knowledge. Ontologies can also be used to define links between different types of semantic knowledge. Thus, ontologies can be used in formulating some data searching strategies.
