Spearman developed two correlational
techniques to pursue research and to prove that the g factor was due primarily to heredity: (1) the Spearman rank-order correlation, and (2) factor analysis - a method of reducing a correlational
matrix into a certain number of factors.
analyses revealed moderate but significant relationships between regular classroom and special education teacher perceptions of problem behavior.
