Generalizability refers to the extent to which research findings can be applied or extended to other populations, settings, or times. It is important for determining the external validity and relevance of a study's results beyond the specific conditions of the research.

Which research method runs the greatest risk of collecting evidence that may be unrepresentative of what generally true?
Convenience sampling runs the greatest risk of collecting unrepresentative evidence, as it involves selecting participants based on their ease of access rather than their representativeness of the population. This method can lead to biased results and limit the generalizability of findings to the larger population.
What are possible limitations of a study?
Possible limitations of a study can include small sample sizes, selection bias, lack of control for confounding variables, reliance on self-reported data, and lack of generalizability to other populations.
What are the disadvantages of using twins studies?
First off, twins are hard to come by. This is especially true of conditions that are already rare, since they do not often have the chance to conduct a twin study due to the low probability of finding an already rare condition in twins. Twin studies are more likely to be case studies, which limit their scope and generalizability. If the twins were raised together, the assumption that similarity in twins is the result of heredity has to compete with the explanation that some similarity is attributable to a common upbringing and not genes alone.

What is the difference between practical generalizability and statistical generalizability?
Statistical: must have random sampling, allows you to generalize to the population from which you randomly selected. Practical: do the results hold for similar individuals? allows you to generalize to similar individuals
What is the major drawback of non-probability sampling compared to probability sampling?
Reduced or limited generalizability

Pierre Paul William Duez has written: 'Testing the generalizability of ecological interface design to computer network monitoring'
What has the author Kurt Kraiger written?
Kurt Kraiger has written: 'Generalizability of walk-through performance tests, job proficiency ratings, and job knowledge tests across eight Air Force specialties' -- subject(s): Job evaluation, Occupational specialties, United States, United States.

What are threats to external validity?
"A threat to external validity is an explanation of how you might be wrong in making a generalization."[4] Generally, generalizability is limited when the cause (i.e. the independent variable) depends on other factors; therefore, all threats to external validity interact with the independent variable.
What is subject selection?
Subject selection refers to the process of choosing participants or subjects for a research study. This process involves identifying and recruiting individuals who meet the specific criteria of the study in order to best answer the research question. Subject selection is critical for ensuring the validity and generalizability of study findings.
What are the demerits of action research?
Some potential demerits of action research include limited generalizability of findings due to the specific context in which the research takes place, challenges in maintaining objectivity and bias in data collection and analysis, and the time and resources required to engage in the iterative process of action research.
How do you criticallly appraise clinical papers?
When critiquing clinical papers, it is important to consider the study design, methodology, results, and conclusions. Look for potential biases, such as selection bias or measurement bias, that may impact the validity of the study. Assess the relevance and generalizability of the findings to your clinical practice and consider the strength of the evidence provided by the study.
What is the differences between external and internal validity in research?
Internal validity has to do with the accuracy of the results. Results could be inaccurate if samples are not selected randomly. External validity has to do with the generalizability of the findings to the population. If the sample selected is only Hispanics under the age of 25, then it would be hard to generalize the results to the entire US population.
Why would it be important to consider selection attrition and history?
Considering selection, attrition, and history is important because they can impact the validity and generalizability of research findings. Selection bias can affect the representativeness of the sample, attrition can lead to missing data and potential bias, and history can confound the results by external events occurring during the study period. By addressing these factors, researchers can improve the rigor and reliability of their findings.
What are the criticism of Edward c Tolman work?
Critics of Edward C. Tolman's work argue that his cognitive maps theory lacks empirical support and is too abstract to be rigorously tested. They also suggest that his emphasis on purposive behavior ignores the influence of unconscious processes and environmental stimuli. Additionally, some critics believe that Tolman's reliance on animal research limits the generalizability of his findings to human behavior.
