PSYB01H3 Chapter Notes - Chapter 5: Emor, Toyota Electronic Modulated Suspension, Content Validity
Document Summary
Define reliability of a measure of behaviour and describe the difference between test-retest, internal consistency, and inter-rater reliability. Describe how a research can build a case for construct validity, including predictive validity, concurrent validity, convergent validity, and discriminant validity. Describe the problem of reactivity of a measure of behaviour and discuss ways to minimize reactivity. Describe the properties of the 4 scales of measurement: normal, ordinal, interval and ratio. Systematic and detailed research on reliability and validity is often carried out on self-report measures on personality and individual differences. Psychologists often use self-report measures to study psychological attributes such as intelligence, self-esteem, extraversion, and depression: for example: neo-pi-r test- neo personality inventory- measuring. Other measures are used in applied settings: clinical, counselling, personnel psychologists use measures to help them make better clinical diagnoses, career-choice decisions, and hiring decisions. Tests that show less variability in measures taken are considered more reliable (see page 95: contains less measurement error, has consistency.
