SOC 390: Social Statistics I

SPSS (50 points)Instructions:For this portion of the exam, you will be provided with a dataset. Make sure you follow all of the directions for each question below (pay attention to details!). When you have completed all of the questions, submit your completed document to Blackboard. Remember to save your work as you go. Round your answers to 2 decimal places. Also, if you get a p-value that = .000, round to .001.

Data: Download/open the SPSS dataset, which is located in the Exam 3 folder: EXAM 3SOC390 data.

RESEARCH SCENARIO 1 [10 points]:

Hypothetically, I collected data on how much participants like statistics (variable name = like_stats) at the beginning of the semester using a scale of 0 = strongly disagree to 4 = strongly agree. After myinitial data collection, I implemented an intervention aimed at improving participants feelings regarding statistics. After the intervention, I measured the same participants with the same measure to get a posttest measure of how much participants like statistics (variable name = POST_like_stats).Help me determine if pretest statistics liking significantly differs from posttest statistics liking. HINT: To avoid confusion regarding sign (+/-) of the observed value, subtract the posttest from the pretest (pretest-posttest) when entering your variables into the SPSS dialog box.

5. Write up your results in APA format. Your write-up should include sample mean(s)/standard deviation(s), t-statistics, degrees of freedom, p-value, and a conclusion. (use the examples from lecture). [3 points]

RESEARCH SCENARIO 2 [10 points]:

I want to compare the mean Exam scores (Variable name = Exam_scores) between different sections of SOC390 (Variable name = Class). In this data set we have three classes (1= Miller, 2 = Field, 3= Smith). Using the SPSS data, conduct a One-way ANOVA where Class is your factor and Exam_scores is your dependent variable. For Post hoc tests, select Tukey. Under Options, select descriptives, homogeneity of variance test, and means plot.6a. Which of the following is the null hypothesis?Highlight or circle your answer.[.5 points]

a) H0: µ1 = µ2 = µ3

8. Interpret:

a. Did the SOC390 sections have significantly different exam scores, in general (yes or no)? What is our conclusion regarding the null hypothesis (reject or fail to reject the null)? [1 point]b. Which output table from above gives you the information to answer 8a (keep in mind I am only asking if the means differed in general)? Highlight or circle your answer. [.5 point]

a) Descriptives

b) Test of Homogeneity of Variances

c) ANOVA

d) Multiple Comparisons

e) Means Plots.c. Using the Multiple Comparisons table from your output above, answer the following and include the appropriate p-value for each (Sig.) to let me know you are not just guessing!

Did Miller and Field significantly differ? [.5 point]

Did Miller and Smith significantly differ? [.5 point]

Did Smith and Field significantly differ? [.5 point]

9. Write up the results from this analysis using APA format. Make sure you include each group mean (and SD) exam score, the correct F stat with the correct degrees of freedom and p-value, decision regarding the null, and the follow-up comparisons (if necessary). Use the example in the SPSS ANOVA lecture to help guide you. [3 points]

RESEARCH SCENARIO 3 [10 points]:

Our dataset includes exam scores from women and men (see variable: sex; 0 = female, 1 = male). We want to test whether or not men and women scored the same on the (made up) exam (variable: Exam_scores).10a. Which of the following is the null hypothesis?Highlight or circle your answer. [.5 points]

RESEARCH SCENARIO 4 [10 points]:

I asked students from SOC390 several questions about their feelings towards statistics. I am interested in how these variables are related to each other. Using the dataset provided, calculate the correlations between the following 5 variables:

like_stats,

anxious,

expect_well,

try_well,

dont_do_well.

For this question, analyze all of the correlations at once (you should get a correlation matrix for output). Be sure to also select Means and standard deviations when running your correlation analysis.15. Paste your output below. You should include the Descriptive Statistics table and the Correlations table. [4 points]

[PASTE OUTPUT HERE]

16. Looking at your correlation matrix above, tell me which two variables were the most STRONGLY correlated. Include the correlation, degrees of freedom, and the p-value (Sig.) for the pair you choose. [2 points]

17. What is the correlation between like_stats and anxious? Is it significant and in what direction? Write up your interpretation/conclusion using APA format. Be sure to include the correlation, degrees of freedom, and p-value [4 points]

RESEARCH SCENARIO 5 [10 points]:

In this section you will interpret output that is provided (you do NOT need to run anything for this scenario).I am interested in testing whether the section of SOC390 that a participant was in (Variable name = Class; 1= Miller, 2 = Field, 3= Smith) influences their exam scores (Variable name = exam_scores). I also think that gender might also influence exam scores (Variable name = Gender; 0 = female, 1 = male). To test this, I conducted a two-way ANOVA. There is a lot of output associated with a two-way ANOVA we are only going to focus on the output below.

18. What are the two factors in this example? How many levels are on each factor?

[2 points]19. What is the dependent variable? [2 points]

20. In the output above, there are two main effects and an interaction effect being tested. First: assuming ? = .05, what are the conclusions for these tests (significant or not significant)? Second: For each, provide the F statistic including degrees of freedom and p-value. [6 points]

Fclass(__, ___) = ______, p = _____? Significant or not significant? ______________

Fgender(__, ___) = ______, p = _____? Significant or not significant? ______________

FclassXgender(__, ___) = ______, p = _____? Significant or not significant? ______________
