Note that the results are displayed in two panels: the first assumes that the variances of the groups are equal, and the second assumes that they are unequal. In this case, the variances of the groups are assumed equal, so we focus on the first panel.

  • The significance values for the tests of the first contrast are both larger than 0.05. This indicates that the 45-54 age group is not significantly more favorable toward the DVD player than the 35-44 age group.
  • Likewise, the significance values for the tests of the second contrast are larger than 0.05. Participants under 35 and over 54 have statistically equivalent assessment scores.
