Which type of reliabilitytests theconsistencyof resultsover timeby administering thesame test more than once. If the method of measuring is accurate, then itll produce accurate results. Random Errors occur when something by chance (randomly) affects the ability to get an accurate measurement. Direction (which mattered in CE, and gets accounted for in total error) no longer matters, Biases that may occur in the selection of participants may negatively impact the validity of the study.
