Question

EXPERIMENT 1    

Part 1:

Dr. Saunders wanted to know whether adolescents who had restricted television viewing time studied more than adolescents who had unlimited television viewing time. She recruited a small sample of children aged 12 to 17 years old; some of these children were allowed limited access to their home televisions, and others were allowed unlimited access. She obtained the following studying time data (in minutes) fore the two groups:

Limited	Unlimited
91	29
68	34
73	65
94	28
75	21
88	57

Enter these data into SPSS in the appropriate manner for the type of analysis you will conduct. Label the columns appropriately.

After you answer questions about the appearance of the information in Data View, you will conduct the appropriate statistical test.

1. Enter all the numbers or words you see in the first column in SPSS data view in the same order they are shown in that column.

Part 2:

Using SPSS compute the appropriate statistical test to determine whether there is a difference in study time between the children with limited vs. unlimited television viewing. Fill in the empty cells based on the output of the statistical test you conducted.

Write your answer to the same number of decimal places as you see in your SPSS output.

Part 3:

k is the t value 5.014

l is the d.f. 10

m is the Sig (2-tailed) 0.001

n is the mean difference   42.5

15. What is the number that should be in blank (K)? 5.014
16. Select the output that goes in blank (L).

10

17. Select the output that goes in blank (M).

.001

Children with limited television viewing do have significantly study more time than who unlimited time viewing television , t(10)=5.014, p=0.001.

Group	M	Difference Between the Means	Standard Deviation	p
Limited	81.50	42.50	10.82	0.001
