A researcher is interested in the pleasure that people obtain from listening to music whilst varying both the volume and the tempo (speed) of the music. 12 participants and randomly allocated into two groups. The different groups listen to the music at different volumes, i.e. soft and loud. The two groups of participants were given three pieces of classical music to listen to. Each piece of music was slow, medium or fast. Participants were asked to rate how much they enjoyed the music on a 20-point scale, where 20 points is highly enjoyable and 1 point is not enjoyable at all.

Which of the following statements is true?

Selecione uma das seguintes:

There are 3 IV's in this study. IV 1 is 'volume' and is a between-subjects variable; IV 2 is 'speed' and is a within-subjects variable. IV 3 is 'music enjoyment' and is a within-subjects variable.

In a mixed-factorial ANOVA, with respect to assumptions, are we concerned with homogeneity of variance or sphericity?

Selecione uma das seguintes:

Both, but the assumption of sphericity only applies when the within-subjects IV has 3+ levels as with repeated-measures designs that are not mixed
Homogeneity of variance only
Assumption of sphericity only, which applies when the within subjects IV has 3+ levels as with repeated measures designs that are not mixed.
Assumption of sphericity only, which applies when the within subjects IV has 2+ levels as with repeated measures designs that are not mixed.

What can you interpret from this output?

Selecione uma das seguintes:

Homogeneity of variance assumption is met; there is an effect of volume on participants enjoyment of music. F(1,10) = 549.39, p < .001, np2 = .98
Homogeneity of variance assumption is met; there is an effect of volume on participants enjoyment of music. F(1,10) = 8.19, p = .017, np2 = .45
Homogeneity of variance assumption is violated; there is an effect of volume on participants enjoyment of music. F(1,10) = 8.19, p = .017, np2 = .45
Assumption of sphericity is met; there is an effect of volume on participants enjoyment of music. F(1,10) = 8.19, p = .017, np2 = .45

What do you understand from this output?

Selecione uma das seguintes:

Assumption of sphericity is violated, and therefore the Greenhouse-geisser values should be reported. There is a significant interaction effect of speed and volume, F (1.73,17.37) = 7.27, p = .007, np2 = .42
Assumption of sphericity is violated, and therefore the Greenhouse-geisser values should be reported. There is a significant main effect of speed, F (1.73,17.37) = 69.21, p < .001, np2 = .87; and a significant interaction effect of speed and volume, F (1.73,17.37) = 7.27, p = .007, np2 = .42
Assumption of sphericity is met. There is a significant main effect of speed, F(2,20) = 69.21, p < .001, np2 = .87
Assumption of sphericity is met. There is a significant main effect of speed, F(2,20) = 69.21, p < .001, np2 = .87, and a significant interaction effect of speed and volume, F (2,20) = 7.27, p = .004, np2 = .42
