    Hi, This is my first time running a logistic regression and I'm not entirely sure how to interpret or graph the results. A basic rundown of my study is that I have used a linguistic analysis tool to quantify emotional tone, how analytical text is, among other variables. The linguistic analysis tool was used on thousands of scientific abstracts some of which did and did not win student research competitions. I wanted to use the linguistic analysis results, as well as word count of abstracts, and gender of participants to see if they are predictors of winning an award in competition. I believe the results are significant even though that have a small effect size but I am unsure of how to graph the results from the SPSS output below. Does anyone know how to?

    From logistic, you can save predicted probabilities and other variables.  Then you can do any number of graphs.  Look particularly at ROC (under Analyze > Classify)
