Data-Analytic Strategies Using Multiple Regression/Correlation
5.1 RESEARCH QUESTIONS ANSWERED BY CORRELATIONS AND THEIR SQUARES
Until this point we have presented regression/correlation analysis as if the typical investigation proceeded by selecting a single set of IVs and producing a single regression equation that is then used to summarize the findings. Life, however, is seldom so simple for the researcher. The coefficient or set of coefficients that provide the answers depend critically on the questions being asked. There is a wealth of information about the interrelationships among the variables not extractable from a single equation. It is, perhaps, the skill with which other pertinent information can be ferreted out that distinguishes ...
