PSYB04H3 Lecture Notes - Lecture 2: Statistical Conclusion Validity, Visual Acuity, Theoretical Definition
Document Summary
Interrogation tools three claims, four validities: claims, frequency. Describes a particular rate or degree of a single variable: association. About two variables, in which the value (level) of one variable is said to vary systematically with the value of another variable: causal. Argues that a specific change in one variable is responsible for influencing the value of another variable: validities, construct. Indication of how well a variable was measured or manipulated in a study: statistical. Extent to which statistical conclusions derived from a study are accurate and reasonable (also called statistical conclusion validity) One of three criteria for establishing a causal claim; the ability to rule out alternative explanations for a causal relationship btwn two variables: external. Indication of how well the results of a study generalize to, or represent, individuals or: variables contexts besides those in the study itself, variable. Anything that can take on more than one value: opposite of a constant.
