New Stats Help Page on Serial Mediation / Sequential Mediation

SerialMediationHi all!

I just uploaded a new page on the “Stats Help” portion of my website.  The link is here: Sobel Test Formula for Serial Mediation / Sequential Mediation .

In short, I spent much too long finding the sobel test formula for the indirect effect of X on Y through M1 and M2 in a serial mediation / sequential mediation.  To prevent this from happening to other researchers (and possibly myself again), I provide a brief summary of mediation, sobel tests, and serial mediation / sequential mediation.  Then, I provide the relevant sobel test formula.

If you want to know more about serial mediation / sequential mediation, please contact me at  I’m always happy to chat about stats!
