Bounds that researchers cannot control
WebWhereas the Research Problem is designed to set up what is not known (i.e., a problem) in the research, the Background gives the reader a broad and often chronological view of the topic and the research that has been conducted on it to the present. WebDec 7, 2024 · One popular way to account for restricted ranges is known as Thorndike’s Case 2, a formula developed by psychometrician Robert L. Thorndike. This formula provides an estimate of the true correlation between two variables and uses the following calculation: True correlation = √ (1- (SD2y restricted-SD2y unrestricted)) * (1-r2restricted) where:
