D) Developing a strong theoretical framework for the study

Question

Quizplus · Accepted Answer

Bias in the dependent variable can arise due to various factors such as confounding variables, measurement errors, and selection bias. To eliminate bias on the dependent variable, the nurse researcher needs to take several steps, such as establishing strict eligibility criteria for the study participants. This ensures that the study participants are similar and reduces the effects of confounding variables that can affect the dependent variable.
While ensuring that all data are collected by a single researcher or formulating at least two hypotheses for each research question can be important steps in conducting research, they do not directly address the issue of bias in the dependent variable. Developing a strong theoretical framework can help ensure that the study is grounded in established knowledge and previous research, but it may not directly eliminate bias in the dependent variable.
