=pearson(a1:a20,b1:b20) The correlation coefficient will appear in that cell. Note: This assumes you have 20 rows. If you have 30 rows, the command will look like this: =pearson(a1:a30,b1:b30) Excel will also draw the scatter plot: Go to Insert/Chart and pick XY Scatter, then Next. Under data range, type “=a1:a20,b1:b20” (for this example).

Click Analyze, Correlate, Bivariate. Scoot both variables into the Variables box. Check Pearson, Spearman, Two-Tailed, and Flag significant correlations. Click OK. The output will give you both the Pearson and the Spearman correlation coefficients and a p value for each. Now prepare a graph of the relationship between homework scores and exam scores.

The significance test for a Pearson correlation coefficient is not robust to violations of the independence assumption. If this assumption is violated, the correlation significance test should not be computed. SPSS© computes the Pearson correlation coefficient, an index of effect size. The index ranges in value from -1.00 to +1.00.
