Question

A mass communications researcher collaborates with a developmental psychologist to determine whether the type of media affects different age groups’ memory for news events. Enter the following data into an SPSS data file:

	Age (Factor A)
		Child	Middle-Aged	Older
Media (Factor B)	TV	14	27	24
		15	23	25
		16	24	24
		20	28	23
		Child	Middle-Aged	Older
	Internet	25	22	13
		23	24	15
		24	21	14
		22	25	18

Use the data to:

1. Create a line graph of the data (Age along the X-axis, Media in the “Set Color” box, and Memory along the Y-axis)
2. Run the between-subjects factorial ANOVA in SPSS, treating Media and Age as fixed factor independent variables and Memory Score as the dependent variable.

Save the output file. You will need to submit it at the end of the test.

Based on the graph, does there appear to be an interaction between Age and Media? If so, which type of interaction? (Select the option that best answers the question)

A. Yes, there appears to be a monotonic interaction.

B. Yes, there appears to be a non-monotonic interaction.

C. No, there appears to be no interaction between Age and Media.

p - value of interaction = 0.0000 < aplha

Hence interaction is significant.
