Researchers intentionally select individuals and sites to learn or understand the central phenomenon
What is purposeful sampling?
100
A first sentence in a statement of the problem section that is easily understood and creates interest, drawing the reader into the study
What is a narrative hook?
100
The range of upper and lower statistical values that is consistent with observed data and is likely to contain the actual population mean
What is the confidence interval or interval estimate?
100
The researcher randomly assigns individuals to groups or to different groups in an experiment
What is equating the groups?
100
A quantitative design in which the researcher administers an instrument to a sample or an entire population to describe attitudes, beliefs, opinions, characteristics, or behaviors
What is a survey design?
200
The process of converting audiotape recordings or fieldnotes into text data
What is transcribing?
200
An issue, concern or controversy investigated by the researcher that narrows down the topic
What is a research problem?
200
The popular form of a standard score having a mean of zero and a standard deviation of 1
What is a z score?
200
Influences in the selection of participants, procedures, statistics, or the design that are likely to affect the outcome and provide an alternative explanation for our results than what was expected
What are extraneous factors?
200
A systematic, qualitative procedure used to generate a theory that broadly explains a process, action, or interaction. This one involves open, axial, and selective coding.
What is a systematic grounded theory design?
300
Stating codes in the participant's actual words
What is in vivo coding?
300
Individuals and groups who will read and potentially benefit from a study
What is the audience?
300
The dispersion of scores around the mean
What is variance?
300
The process of identifying one or more personal characteristics that influence the outcome and assigning individuals with that characteristic equally to the experimental and control groups, e.g. gender, individual abilities, pretest scores
What is matching?
300
A good one reports the story of lived experiences of an individual and organizes them into a chronology
What is a narrative research design?
400
Themes that are surprising and not expected to surface during a study
What are unexpected themes?
400
The major intent or objective of a study
What is the purpose?
400
The mean, median, and mode
What are measures of central tendency?
400
Problems that threaten our ability to draw correct inferences from the sample data to other persons, settings, treatment variables, and measures
What are threats to external validity?
400
This design is used when you want to relate two or more variables to see if they influence each other. It allows you to predict an outcome.
What is a correlational design?
500
The point where you have identified the major themes and no new information can add to your list of themes or to the detail for the existing themes
What is saturation?
500
A problem based on a gap in research or a need to extend existing research into other areas
What is a research-based research problem?
500
The most widely used way of describing the spread of a group of scores, calculated by figuring the variance and taking the square root
What is standard deviation?
500
The most rigorous form of experimental design, in which groups are equated through random assignment
What is a true experiment?
500
Among its characteristics are fieldwork, a context or setting, and shared patterns of behavior, belief, and language
