With respect to RELIABILITY, explain the terms: 1. Dependability 2. Equivalence 3. Internal consisetncy 4. Rater consistency

1. Dependability - correlation between test – retest results, correlation coefficients (you can depend on it through the time) 2. Equivalence - correlation between two and more test variants (you measurement tool will be sensitive and difficult in the very same way regardless of variants), 3. Internal consisetncy - a measure based on the correlations between different items on the same test 4. Rater consistency - = intra-rater and inter-rater reliability, “kappa” coefficients: Fleiss’ kappa, Cohen’s kappa, Scott’s pi,… → to be reliable raters, you have to prove your rater consistency with respect to other raters
