how is content validity established quizlet

- Roughly looking at the items might provide some evidence of content validity. this validity evidence considers the adequacy of representation of the conceptual domain the test is designed to cover . Content validity is most often addressed in academic and vocational testing, where test items need to reflect the knowledge actually required for a given topic area (e.g., history) or job skill (e.g., accounting). significant results must be more than a one-off finding and be inherently repeatable In contrast, internal validity is the validity of conclusions drawn within the context of a particular study. Type # 2. CONTENT validity -- extent to which the items on a test are representative of the construct the test measures-- (is the right stuff on the test?) Also called concrete validity, criterion validity refers to a test’s correlation with a concrete outcome. In the case of pre-employment tests, the two variables being compared most frequently are test scores and a particular business metric, such as employee performance or retention rates. Predictive validity is regarded as a very strong measure of statistical validity, but it does contain a few weaknesses that statisticians and researchers need to take into consideration. Internal and external validity are like two sides of the same coin. Face Validity can’t be established with any sort of statistical analysis. outside established criteria. In psychometrics, criterion validity, or criterion-related validity, is the extent to which an operationalization of a construct, such as a test, relates to, or predicts, a theoretical representation of the construct—the criterion. To demonstrate content validity, testers investigate the degree to which a test is a representative sample of the content of whatever objectives or specifications the test was originally designed to measure. people can guess what answer is most appropirate if they knew what it is measuring. Construct validity is "the degree to which a test measures what it claims, or purports, to be measuring." Another way of saying this is that content validity concerns, primarily, the adequacy with which the test items adequately and representatively sample the content area to be measured. In this article, we argue that reliability and validity remain appropriate concepts for attaining rigor in qualitative research. content validity. criterion related validity. any outcome measure against which a test is validated. Strategy to mitigate a threat in the selection of validity is a particular choice or action used to increase validity by addressing a specific threat according to (“Threats to Validity and Mitigation Strategies in Empirical.,” n.d.). 1.1. For surveys and tests, each question is given to a panel of expert analysts, and they rate it. Face Validity can’t be established with any sort of statistical analysis. A test has content validity if it measures knowledge of the content domain of which it was designed to measure knowledge. a judgement/estimate of how well a test measures what its supposed to within a particular context, evaluating of the subjects, topics, or content covered by the items in a test, evaluating the relationship of scores obtained on the test to scores on other tests/measures, degree to which a test score is related to some criterion measure obtained at the same time, degree to which a test score predicts some criterion measure in the future, -how scores on the test relate to other scores/measures, homogeneity (uniform), changes, pretest/posttest changes, distinct groups, correlate highly in the predicted direction with the scores on older, more established tests designed to measure the same constructs, showing little relationship between test scores and other variables with which scores on the test should NOT theoretically be correlated, a new test should load on a common factor with other tests of the same construct, a judgement concerning how relevant test items appear to be, how much a test samples behavior is representative of the universe of behavior that the test was designed to sample, recruiting a team of experts on the subject matter and obtaining expert ratings on the degree on importance as well as scrutinize whats missing from the measure, a correlation coefficient between test scores and score on the criterion measure, the degree to which an additional predictor explains something about the criterion measure that is not explained by the predictors already in use, : a factor inherent in a test that systematically prevents accurate, impartial measurement, a judgment resulting from the intentional or unintentional misuse of a rating scale, The extent to which a test is used in an impartial, just, and equitable way, the usefulness or practical value of a test, -economic costs: purchasing a test, s supply bank of test protocols, computerized test processing, -successful testing programs yields higher worker productivity and company profits, cost benefit analysis designed to determine the usefulness and practical value of an assessment tool, -judgements of experts are averaged to yield cut scores for the test, -collection of data on the predictor of a interest group known to posses and not to posses a trait/attribute/ability of interest, each item is associated with a particular level of difficulty, statistical techniques used to shed light on the relationship between identified variables and two naturally occurring groups.
