st095 20_q_Visualize relationship

  • 0:00 - 0:07
    This is a scatter plot visualizing the
    data in this table. Each point represents
  • 0:07 - 0:13
    one row of the table. Here you can see
    that the hours slept was about 5 and the
  • 0:13 - 0:19
    temporal memory score looked to be about
    55. That most correspond to this row here
  • 0:20 - 0:26
    5, 56. You can see that hours slept is on
    the x-axis and temporal memory score is on
  • 0:26 - 0:32
    the y-axis. We call the variable on the
    x-axis the independent variable or the
  • 0:32 - 0:38
    predictor variable. And we call the
    variable on the y-axis the dependent
  • 0:38 - 0:44
    variable or the outcome. We're trying to
    predict temporal memory score using hours
  • 0:44 - 0:49
    slept. Now that you've seen this data
    visualized, is there a relationship
  • 0:49 - 0:55
    between hours slept and temporal memory
    score? The more you sleep, the better your
  • 0:55 - 1:01
    temporal memory score. The more you sleep,
    the better you'll do on a test. The more
  • 1:01 - 1:06
    you sleep, the worse your memory or there
    is no relationship.
