The biviariate Pearson correlation coefficient and corresponding significance test are not robust when independence is violated. Since this is slightly below the weak positive range (.10 to .29), we may say that there is a very weak positive relationship between our two variables (the number of questions that people answered correctly in a logic test and the amount of time in seconds it took them to complete the test). This is because of missing data -- there are more missing observations for variable Weight than there are for variable Height. How to Report Pearson's r (Pearson's Correlation Coefficient) in APA Style The APA has precise requirements for reporting the results of statistical tests, which means as well as getting the basic format right, you need to pay attention to the placing of brackets, punctuation, italics, and so on.

Results of the Pearson correlation indicated that there was a significant positive association between transformational leadership and job satisfaction, (r(112) = .60, p = .012). Results of the Spearman correlation indicated that there was a significant positive association between years of experience and job satisfaction, (rs(112) = .53, p < .001). The sign of the correlation coefficient indicates the direction of the relationship, while the magnitude of the correlation (how close it is to -1 or +1) indicates the strength of the relationship. The sample regression table shows how to include confidence intervals in separate columns; it is also possible to place confidence intervals in square brackets in a single column (an example of this is provided in the Publication Manual ). Sample tables - APA Style It is good practice to create scatterplots of your variables to corroborate your correlation coefficients. %PDF-1.3 This gave us Span variables that were moderately correlated with the Effect variables, with correlation coefficients ranging from 0.14 to 0.31.
