Solution Chapter 2 Reliability And Validity Studypool See why predictive validity is desirable but not essential for a measure distinguish the only two important types of reliability, which are stability of scores reliability and precision of scores reliability. This unit mainly concerns about various problems that can threaten the reliability and validity of conclusions drawn by the researcher. there are two goals of research design; 1) obtain information relevant to the purposes of the study. Through reliability, a researcher identifies consistency of results across different observations, time, and parts of the test itself. on the other hand, validity tells the researcher about the extent to which the results are closest to what is being measured.

This unit mainly concerns about various problems that can threaten the reliability and validity of conclusions drawn by the researcher. there are two goals of research design; 1) obtain information relevant to the purposes of the study. Reliability establishes the accuracy and involves the degree to which scores correlate with each other, while validity concerns the nature of the construct measured, and involves how well a research technique measures the behavior a researcher claims it does (coaley, 2014). Validity concerns what an instrument measures, and how well it does so. reliability concerns the faith that one can have in the data obtained from the use of an instrument, that is, the degree to which any measuring tool controls for random error. Validity and reliability are critical components in assessing the quality of research findings. validity refers to the degree to which a study accurately measures what it intends to.
