fMRI Power Analysis with NeuroPower



One of my biggest peeves is complaints about how power analyses are too hard. I often hear things like "I don't have the time," or "I don't know how to use Matlab," or "I'm being held captive in the MRI control room by a deranged physicist who thinks he is taking orders from the Quench button."

Well, Mr. Whiny-Pants, it's time to stop making excuses - a new tool called NeuroPower lets you do power analyses quickly and easily, right from your web browser. The steps are simple: Upload a result from your pilot study, enter a few parameters - sample size, correction threshold, credit card number - and, if you listen closely, you can hear the electricity of the Internet go booyakasha as it finishes your power analysis. Also, if a few days later you notice some odd charges on your credit card statement, I know nothing about that.

The following video will help you use NeuroPower and will answer all of your questions about power analysis, including:

  • What is a power analysis?
  • Why should I do a power analysis?
  • Why shouldn't I do a power analysis on a full dataset I already collected?
  • How much money did you spend at Home Depot to set up the lighting for your videos?
  • What's up with the ducks? "Quack cocaine"? Seriously?

All this, and more, now in 1080p. Click the full screen button for the full report.

    1. Yes, I just noticed that as well. I'm not sure why that happened; it's too bad, since I just made a video promoting their site. Maybe it'll be back up soon.
