Pregunta 2
Pregunta
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 at all enjoyable.
Which of the following statements are true?
Respuesta
-
There are 2 IVs in this study. IV 1 is 'volume' and it is a between subjects variable; IV 2 is 'speed' and it is a within subjects variable
-
There are 3 IVs in this study. IV 1 is 'volume' and it is a within subjects variable; IV 2 is 'speed' and it is a between subjects variable. IV 3 is 'music enjoyment' and it is a within subjects variable
-
There are 3 IVs in this study. IV 1 is 'volume' and it is a between subjects variable; IV 2 is 'speed' and it is a within subjects variable. IV 3 is 'music enjoyment' and it is a within subjects variable
-

Pregunta 5
Pregunta
In a mixed factorial ANOVA, with respect to assumptions, are we concerned with Homogeneity of variance or Sphericity?
Respuesta
-
Both, but 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.
