Question

Laptops:

The table contains created data based off of a research study by Sana and colleagues (2013) in which they investigated the use laptops in college classrooms. Identify the appropriate test to determine if multitasking on a laptop hinders learning, as measured by performance on a comprehension test, compared to those who are not multitasking on a laptop.

Table: Proportion Correct Answers for Multitasking and No Multitasking Groups

Laptop Multitasking	Laptop No Multitasking
0.55	0.65
0.6	0.70
0.4	0.6
0.5	0.55
0.45	0.5
0.35	0.60
0.45	0.75
0.55	0.7
0.6	0.65
0.7	0.8
	0.75

2) Identify the appropriate hypothesis test needed to test for statistical significance and state WHY you chose that test. (1 point)

3) Run the test (in SPSS) and upload your output with the portion used to determine significance circled. (2 points)

4) State in words if the result is statistically significant. (1 point)

5) Make the appropriate graph in SPSS (or another computer program) and include the graph in the same file. (2 points)

6) Summarize and interpret your results in 2-3 sentences (using APA format if appropriate). (2 points)

Answer 1

2)

H0: There is no significance difference between the means of two groups
H1: There is significance difference between the means of two groups
Let the los be alpha = 5%

3) SPSS Output:

4) P-value = 0.003 which is less than alpha = 0.05 so we reject H0

5) Red color is Rejected region:

6) Thus we conclude that  there is significance difference between the means of two groups
