Document Summary

Interpreted as: the probability that the value observed in the sample (usually a difference in means) is due to chance, i. e. it doesn"t reflect a real difference in the population. The traditional standard for acceptable levels is 0. 05. Main effects reflect the influence of an explanatory variable (e. g. , an experimental condition) on an outcome variable without considering any other explanatory variables. Significant interaction effects indicate that the effect of an explanatory variable on an outcome variable depends on some other variable. It = the relationship between two variables (not the outcome variable per se) The variable that tell you what it depends on. The gold standard for inferring a causal relationship are experiments with random assignment. Many times it is often helpful and practical to also measure how variables are related to one another, but correlation among variables doesn"t necessarily indicate causation. Mediating variables seek to uncover the process by which x effects y.
