A Primer on Partial Correlation Coefficients.
Waliczek, Tina M.
Part and partial correlation coefficients are used to measure the strength of a relationship between a dependent variable and an independent variable while controlling for one or more other variables. The present paper discusses the uses and limitations of partial correlations and presents a small heuristic data set to illustrate the discussion. The correlation of interest was between the number of churches and the number of murders in 15 cities of various populations. The Statistical Package for the Social Sciences was used to analyze the data. Interpretation of the partial correlation value is discussed. It is demonstrated that about 50% of the variance in the number of murders can be associated with the variance in the number of churches when population is being controlled.
