• Brief video showing data entry in SPSS in preparation to run Pearson correlation https://www.youtube.com/watch?v=jexXeAoymh4 (my notes with SPSS do not show how data were enter because an existing data file was used). For JASP, the process is the same except one enters data into a spreadsheet in the same way as illustrated in this video, then open spreadsheet in JASP to run the correlation.
