7. Evaluate the construct validity of the predictor/independent variable Group of answer choices The construct is valid The construct is valid because glucose levels are, on the face of it, a good way to measure hunger. Directly monitoring a physiological change is a strong method match. Using a standard glucose monitoring kit means that all participants completed the same procedure so the procedure should not add any noise to the measurement. The construct is invalid because glucose levels are not, on the face of it, a good way to measure hunger. Even though glucose levels have been measured with an appropriate method match (directly monitored) and even though there was no noise added by the procedure (all participants using a standard monitoring kit) the resulting data will not tell us anything about the participant's hunger. The construct is invalid because it lacks procedural validity. Even though they are directly monitoring a physiological states and even though that state has strong face validity the procedure is flawed.
