The logic of purposive sampling is:

That a random sample can generalize to a population. That a few information-rich participants studied in depth yield many insights about a topic.page no (90) To include all participants, even though they are not all relevant to the problem. To use participants because the researcher has access to them.

Refrence:

In contrast, the logic and power of purposive sampling lies in selecting information-rich cases for study in depth.

An indicator of reliability based on the correlations of each item in a measure with every other item is called:

Cronbach's alpha

Split-half reliability Inter item ratio

refrence:

Another internal consistency indicator of reliability, called Cronbach's alpha, is based on the individual items. Here the researcher calculates the correlation of each item with every other item.

Why does qualitative interviewing have an advantage over participant observation when it comes to longitudinal research?

Repeat interviews are easier to organise. It allows for a better exploration of key issues. It is a more focused research method. Participant observers are prone to 'go native' during longitudinal research.

Refrence: Re-visiting research sites for follow up interviews is likely to be easier than arranging a series of subsequent observations.

An operational definition is:

One that bears no relation to the underlying concept. An abstract, theoretical definition of a concept. A definition of a concept in terms of specific, empirical measures. One that refers to opera singers and their work.

Refrence:

Operational definition is also called a working definition stated in terms of specific testing or measurement criteria. The concepts must have empirical referents (i.e. we must be able to count, measure, or in some other way gather thee information through our senses).

To say that a theory is falsifiable is to say that;

It is based on results that are not replicable. Investigators have replaced it with a simpler or more accurate theory. We can imagine results that would contradict it. It is so vague that it fits any and all possible results.

Refrence:

Falsifiability. A good theory is falsifiable. If there is no conceivable way to construct an experiment or collect some data that could potentially contradict the theory, the theory is

Which type of research address major societal change?

Experimental Research Action Research Social Research Historical Comparative Research

Refrence:

Historical comparative research is a powerful method for addressing big questions: How did majorsocietal change take place? What fundamental features are common to most societies? Why did currentsocial arrangements take a certain form in some societies but not in others?
