This type of research seeks to investigate differences between two or more different programs, methods, or groups.
What is causal-comparative research?
100
The observer becomes a part of and a participant in the situation being observed.
What is participant observation?
100
The most commonly used measure of central tendency.
What is the mean?
100
In the QUAL-quan model, qualitative data are collected first and are more heavily weighted than quantitative data.
What is the exploratory mixed methods design?
100
A sampling procedure of strategically selecting a sample in such a way that guarantees desired representation of relevant subgroups within the sample.
What is stratified sampling?
200
A researcher's prediction of the research findings.
What is hypothesis?
200
The study of the lives of individuals as told through the stories of their experience, including a discussion of the meaning of those experiences for the individual.
What is narrative research?
200
The difference between the highest and lowest score in a distribution; it is computed by subtraction.
What is the range?
200
Quantitative data are collected first and are more heavily weighted than qualitative data.
What is the explanatory mixed methods design (QUAN-qual model)?
200
The group to which a researcher would ideally like the results of a study to be generalizable.
What is a population?
300
The degree to which a test measures what it is supposed to measure, thus permitting appropriate interpretations of test scores.
What is validity?
300
This study design uses inductive, interactive, and repetitious collection of unstructured data and analytic strategies to build local cultural theories.
What is ethnographic research?
300
A normal, or bell-shaped, curve.
What is the normal curve?
300
The use of at least two methods, usually qualitative and quantitative, to address the same research problem.
What is methodological triangulation?
300
A sampling procedure in which every Kth individual is selected from a list of all members in the population.
What is systematic sampling?
400
Give one group the same test at two different times, and correlate the two scores.
What is test-retest reliability?
400
A qualitative research approach in which researchers focus on a unit of study known as a bounded system. It is an all-encompassing method covering design, data collection techniques, and specific approaches to data analysis.
What is case study research?
400
A statistical level of probability at which we can confidently reject the null hypothesis.
What is tests of significance?
400
The use of the qualitative and quantitative methods at the same time.
What is simultaneous triangulation?
400
Sample selection is based on the researcher's knowledge and experience of the group to be sampled using clear criteria to guide the process.
What is purposive sampling?
500
In this type of study, the researcher manipulates at least one independent variable, controls other relevant variables, and observes the effect on one or more dependent variables.
What is experimental research/study design?
500
Qualitative researchers can establish credibility, transferability, dependability, and confirmability of their studies and findings.
What is trustworthiness?
500
The researcher incorrectly rejects a null hypothesis when the null hypothesis should have been retained.
What is Type I error?
500
The results of one method are essential for planning the next method.
What is sequential triangulation?
500
This sampling procedure has fewer sampling point and makes it less likely to produce a representative sample.
