Reading research critically: results using correlation coefficients.
Statistical tests you have heard of, designed primarily to characterize relationships between and among variables within a data set, are correlations and regressions. Tests designed to analyze the difference among groups on a particular variable are the chi-squared test, the Student's t Test, and the analysis of variance. This article will explain the interpretation of simple relationships in research data, specifically correlations.
