======================

Roc curve is present in new versions of SPSS like SPSS V.23 . And now SPSS V.25 can be downloaded online.

=======================

For me I prefer to use MedCalc program in ROC curve as it has many options rather than SPSS. Adding on Sample size calculator.

1. If the sample size of each group is >30, you can develop two independent T test.

2. Otherwise, non-parametric T test has to be developed.

3. For more information, please refer to:
