Determining effect st095 L8

  • 0:00 - 0:05
    Thanks for doing that. So now remember, we're trying to decide if me singing a
  • 0:05 - 0:09
    song that I wrote about hypothesis testing is going to increase your engagement
  • 0:09 - 0:14
    in learning. In the last example, confidence intervals were really great when we
  • 0:14 - 0:19
    were trying to estimate the actual population parameters. For example, the
  • 0:19 - 0:25
    engagement ratio from our example before. In this case, the dependent variable,
  • 0:25 - 0:30
    so the engagement ratio, makes sense by itself. We understand what that means.
  • 0:30 - 0:34
    The number of minutes students spend watching the course to the, the total
  • 0:34 - 0:39
    amount of minutes that are available. In this case, we don't care as much what
  • 0:39 - 0:43
    the actual score between 1 and 10 will be, we just want to see if the
  • 0:43 - 0:46
    intervention, or the song, possibly has an effect.
