Answer 3 for DNP 820 Compare validity and reliability and explain why measurement tools used for your DPI Project need to be valid and reliable

I agree with you that measurement is a critical component of research.  Measurement allows researchers to identify the difference generated after the research. Therefore, the measurement examines the difference between an intervention and controlled group. The measurement details are important in informing researchers about the impact of their study. Similarly, measurements allow researchers to determine the effectiveness of an intervention (Pop & Khampirat, 2019). Unsuitable intervention mechanisms can be detected and addressed after conducting a reliable measurement routine. Validity and reliability are two primary aspects assessed when measuring (Worobey et al., 2020). Validity assesses the accuracy of the measurement whereas reliability focuses on the consistence of the findings. Measurement tools used for the DPI project should be reliable and valid. A research study can have reliability without validity. Therefore, researchers based on the kind of information they want in the research may choose their most preferred measurement tools for use.
