External validity refers to the extent to which the results of a study can be generalized beyond the specific context of the study to other populations, settings, times, and variables.| Simply Psychology
Sampling methods in psychology refer to strategies used to select a subset of individuals (a sample) from a larger population, to study and draw inferences about the entire population. Common methods include random sampling, stratified sampling, cluster sampling, and convenience sampling. Proper sampling ensures representative, generalizable, and valid research results.| Simply Psychology
In psychology, random assignment refers to the practice of allocating participants to different experimental groups in a study in a completely unbiased way, ensuring each participant has an equal chance of being assigned to any group.| Simply Psychology
In psychology research, validity refers to the extent to which a test or measurement tool accurately measures what it's intended to measure. It ensures that the research findings are genuine and not due to extraneous factors. Validity can be categorized into different types, including construct validity (measuring the intended abstract trait), internal validity (ensuring causal conclusions), and external validity (generalizability of results to broader contexts).| Simply Psychology
Sampling bias occurs when certain groups of individuals are more likely to be included in a sample than others, leading to an unrepresentative sample.| Simply Psychology
