PSYB30H3 Lecture Notes - Lecture 2: Inter-Rater Reliability, Random Assignment, Takers
Document Summary
Ask them about questions about themselves (self-report) Ask other people what they think about that person. Use the scientific method: eliminates biases, systematic no other variables that could impact your results, foundation of all psychological research, describes how to make and test observations, draw conclusions, minimize error, publish results, tools. Someone observing the same phenomena and see whether they report the same thing. = high inter-rater reliability: used to determine causality whether one variable causes another, two key requirements: Subject variables = characteristics that are inherent of the subject which can not be manipulated. Ensuring that participants in each experimental condition are equivalent to each other. By random assignment to different conditions random assignment may not work if you have small sample sizes (cid:1) Negative inversely proportional: does not indicate causation. Third variable problem: size of correlations. Strength of relationships the closer the number is to.
