PSY 370 Lecture Notes - Lecture 4: Likert Scale, Assessment Centre, Conscientiousness
Document Summary
Based on theory, research, ksaos (knowledge, skills, abilities and other characteristics) What works and what doesn"t: sometimes the best thing to do with an existing scale that works, you adapt it to what you"d like to measure. Still have to verify and evaluate its performance. You don"t want to build things from scratch if you don"t have to. The testing universe: explains what the test is intended to measure , and what it isn"t. Example: do items about tidiness belong in a test of conscientiousness: be specific and clear. Need to know this for item writing make sure you"ve captured all the important aspects. Will test this later on but need to start with some idea. ** how complex do you think the construct is ** Big picture theory of how my construct fits into everything else. Need this for item writing which items really capture the construct? and also validation.
