Question

Quizplus · Accepted Answer

The nurse researcher is using randomization, which involves assigning subjects to the experimental and control groups randomly in such a way that every subject in the population has an equal chance of being selected. Randomization helps to reduce the risk of bias in the study and increases the likelihood that any observed effects are due to the intervention being tested rather than other factors such as participant characteristics or confounding variables. Selection bias refers to a situation in which the selection of participants for a study is not random and is therefore subject to bias. Convenience sampling involves selecting participants who are readily available and willing to participate, which can introduce bias into a study. Internal validity refers to the degree to which a study accurately measures what it is intended to measure, and is not directly related to the method of participant selection.
