Question

Assignment Instructions:

As you probably remember for SPSS 2 Assignment, researchers were interested in how females rated their closest female friend on levels of satisfaction, intimacy, emotional support, loyalty, and tangible help. To do this, 100 female participants completed measures of:

1.Basic demographics:

a.age in months (Variable name “sage”)

b.ethnicity (Variable name “sethnic”)

c.year in college (Variable name “college”)

d.where they live now (Variable name “whlive”)

e.the family composition of the house they grow up in (Variable name “house”)

2.The number of female friends they currently have (Variable name “fnum”)

3.The length of the friendship with their closest female friend (Variable name “flength”)

4.Satisfaction with their closest female friendship (Varialbe name “Satisfaction”)

The following variables were computed in SPSS 2 Assignment and will be utilized in rest of the SPSS assignment.

5.Friendship quality with their closest female friend:

a.Intimacy (Variable name “fgill2”, “fgill7”, “fgill9”, “fgill16”, “fgill18”, “fgill21”, “fgill25”, and “fgill30”)

b.Emotional Support (Variable name “fgill3”, “fgill5”, “fgill11”, “fgill13”, “fgill19”, “fgill23”, “fgill27”, and “fgill32”)

c.Loyalty (Variable name “fgill4”, “fgill6”, “fgill12”, “fgill14”, “fgill20”, “fgill22”, “fgill28”, and “fgill29”)

d.Tangible Help (Variable name “fgill1”, “fgill8”, “fgill10”, “fgill15”, “fgill17”, “fgill24”, “fgill26”, and “fgill31”)

The researchers know that the rating of intimacy and emotional support will be similar and the ratings of intimacy will be different from their ratings Tangible Help. Because these ratings are made by the same people on the same friend, the scores are linked. As we learned from the text and the PPTs, we know these research situations require the use of the Paired Sample t Tests. Here are the researchers’ hypotheses:

1.The researchers think that our group of 100 females will rate intimacy and emotional support the same.

2.The researchers think that our group of 100 females will rate intimacy and Tangible Help differently.

Use the SPSS data to make conclusions.

Part 1—The Analyses

1.For this assignment, I ran 2 Paired Sample t Tests: one for Intimacy and Emotional Support and one for Intimacy and Tangible Help. Here is a screen shot of what that looked like. If you want to know the exact steps for performing that test, follow the instruction in Chapter 7.

Part 2—The APA Write-Up Instructions

                The American Psychological Association (APA) has standards for how statistical results should be presented. While the actual word choice varies, there are several essential components that are common among all presentations of statistical results and interpretations. Use the following instructions for ALL APA write-ups required for this course:

For each analysis, use the following steps to write a complete description of results in proper APA format.

1.State what hypothesis was tested.

2.State what test was used.

3.What decision did you make? Reject the null or retain (fail to reject) the null.

4.Were the groups significantly different from each other?

5.Report the means and standard deviations for each group.

6.Put numbers in APA format:

a.General Format: symbol for the test (df)= obtained value, p> or < significance level

b.Specific for t Tests: t(99)=1.98, p<.05

7.Report Effect Size (if known)

Example:

        Adolescent males were expected to score significantly higher on a measure of aggression than were adolescent females. An independent t test was used to test the hypothesis leading to the rejection of the null hypothesis. Adolescent males (M=14.67, SD=2.35) were significantly more aggressive than were adolescent females (M=9.65, SD=1.59), t(78)=3.93, p<.05.

Since we ran 2 analyses, you will do 2 write-ups for this assignment.

Explanation / Answer

1. Females were expected to give same rating to intimacy and emotional support. A paired t test is used leading to rejection of null hypothesis. Females were found to rate intimacy (M=58.36, SD=6.89) significantly different from emotional support (M=56.44, SD=8.27), t(99)=3.57,p<0.05.

2. Females were expected to give higher rating to intimacy than tangible help. A paired t test is used leading to rejection of null hypothesis. Females were found to rate intimacy (M=58.36, SD=6.89) significantly lesser from tangible help (M=55.61, SD=8.09), t(99)=5.32,p<0.05.
