What research studies the same group of participants over time?
A longitudinal study
can be used to discover relationships between variables that are not related to various background variables. This observational research technique involves studying the same group of individuals over an extended period.
What do you call the participants in your research study?
Subject
: subject or ‘human subject’ is a term describing the person who volunteers to be in a research experiment. Also called a research participant.
Is generalizability a limitation?
How Generalizable are these Results? The generalizability of this study
is limited by the characteristics of the study participants
. … These differences may limit the generalizability of the study to older populations, or, in other words, the results may not apply to older adults.
What is the best way to ensure that results of a study are generalizable to a population?
The best way to ensure representativeness is
to sample randomly
However, since the nature of sampling in qualitative research is non-probabilistic, this type of generalization in qualitative research is a weak point.
What group does not get the experimental treatment?
The control group
is composed of participants who do not receive the experimental treatment. When conducting an experiment, these people are randomly assigned to be in this group.
What was the primary conclusion of Stanley Milgram’s obedience research?

.
What are the limits to generalizability in terms of external validity?
“A threat to external validity is an explanation of how you might be wrong in making a generalization from the findings of a particular study.” In most cases, generalizability is
limited when the effect of one factor (i.e. the independent variable) depends on other factors
.
What is the difference between external validity and generalizability?
External validity is a function of the researcher and the design of the research. Generalizability is
a function of both the researcher and the user
.
Why the findings of qualitative research Cannot be generalized across the population?
In addition to concerns about generalizability, qualitative methodology is rebuked because
studies are often difficult to replicate
. Future researchers may not have access to the same subjects, and if other subjects are used, results may differ.
