This video builds on the discussion from my previous video [Part 1: youtu.be/ySBvgNlDo7U], providing more computational details and details regarding features of the macro.

Dear viewers: I was made aware (and have experienced myself) a few issues with using the menus interface with SPSS version 27 (the most recent version). Version 26 is what I used in this video. I was recently informed by Professor Hayes of an alternative approach to generating McDonald's omega that can be used with SPSS version 27 (or any for that matter), which can be an effective stop-gap, until the programming issue gets resolved on the drop-down menu approach. I just put together a video on a solution here: youtu.be/xscn5M5iLKQ . That video is less conceptual than the video here, so I still encourage you to watch this one for more details!
