Advantages of Correlational Research 1. Allows you to analyze the relations among a large number of variables in a single study. Provides information concerning the degree of the relationship between variables. While demonstrating relations between variables, not demonstrated causal relations is x affecting y on the opposite Y affecting y. 2. With large sample, defect significant correlations through shotgun approach or through massive numbers despite solid English.
Correlation coefficients show how one variable predicts another.
The variable that precedes the other is the predictor variable , and the predicted dependent variable is called the criterion variable. Data for developing theory about the determinants of the criterion behavior pattern. Keep in mind that causation is not inferred from correlation. Sometimes we don't know what causes what. The heterogeneity of the population, restriction of score, reliability and range of scores.
