How do I obtain 95% Confidence Intervals for a (Pearson) correlation in SPSS?
Suppose we have two variables, X and Y we wish to correlate. To obtain the 95% Confidence Interval for their correlation firstly standardise the two variables by subtracting their mean and dividing by their standard deviation. This can also be done using CROSSTABS in the EXPLORE menu.
Perform a linear regression using one of the standardised variables as the predictor of the other after selecting 95% confidence intervals for the regression estimate in the window obtained by clicking on the statistics button in the regression window.
