Sample-size planning – a short video

Posted on Posted in Open Science, Replication, The New Statistics No Comments

Here’s a short talk I gave at the 2017 Society for Neuroscience meeting on sample size planning.  The talk discusses:

  • Why you should plan your sample sizes in advance
  • What not to do (how some common approaches can lead you astray)
  • What an effect size is and why it’s important to have a sense of effect sizes
  • How to plan a sample for power
  • Even better, how to plan a sample for precision
  • Resources to get you started (with the talk, script, and resources posted here: https://osf.io/5awp4/)

All in 25 minutes.  Whew.  SFN taped the talk and made a fancy video.  Unfortunately, they made the video available only to members.  This is the copy I liberated from the SFN website.  Viva la revolucion.
