  • If you observed a correlation of r=0.21 with 50 subjects, how confident would you be that this didn't occur due to chance (that the null hypothesis \rho = 0 is false)?
  • ?
  • If you observed a correlation of r=0.21 with 50 subjects, how confident would you be that you could replicate this with another 50 subjects
    • ... to get a correlation that was >0
      ?
    • ... to get a correlation that was significantly >0
      ?
    • ... to get a correlation that close to the same r-value
