Module 2
SPSS Exam
Application of Descriptive Stats

1. (10 points) Using SPSS, please create a frequency table and frequency graph appropriate for the following study. The Psychology Department is trying to who is taking their Behavioral Statistics course so they can design their course accordingly. Surveys were administered to 30 Statistics Students who were randomly selected from classes being offered at ABC College.

The following data was collected:

Participant (denoted Pn) Career Participant (denoted Pn) Career
P1 Psychology P16 Sociology
P2 Sociology P17 Psychology
P3 Sociology P18 Psychology
P4 Psychology P19 Psychology
P5 Psychology P20 History
P6 Psychology P21 Political Science
P7 Psychology P22 Sociology
P8 Psychology P23 Psychology
P9 Psychology P24 Psychology
P10 History P25 Psychology
P11 Communications P26 Psychology
P12 Sociology P27 Sociology
P13 Other P28 Anthropology
P14 Other P29 Other
P15 Business P30 Psychology

a. Based on what you learned in the first and second module, what type of data are you working with for this study? Is it Discrete vs. Continuous? What Scale of Measurement applies?
b. Enter the data into SPSS. Based upon the type of data you have, determine if you need to code the data within SPSS and proceed accordingly.
c. Create a frequency table and frequency graph for this data and embed those here. Be sure to think about which graph is appropriate based on the type of data reflected in the problem.
d. Run the Descriptive Statistics (Measures of Central Tendency/Measures of Variability) for the data set in SPSS and paste the results directly into this document here.
e. Provide a narrative description of the output in order to explain and interpret the data accordingly. Be sure to provide a detailed analysis applying all relevant key terms and concepts that have been addressed in the course thus far. Provide terms and definitions where appropriate. Additionally explain your choices in terms of which graph you selected and which measures you report. All analyses should include the following components:
i. Explain your choices in terms of which graph you selected and why.
ii. Thoroughly analyze the distribution of the data set. Analyze the shape of the distribution. Is it skewed? Is it a normal distribution? Is it symmetrical? Are there outliers? Is there anything else about the shape of the distribution that is important to address based on the specific data and research question?
iii. Analyze and explain your Descriptive Statistics. Based on the type of data, and the distribution of the data set, what measures of central tendency are appropriate to report and why? What measures of variability do your report and why?
iv. Finally, consider what conclusions can be drawn as a researcher to address the original questions. What specific and broader advice might you offer to the researcher based on the original intent of the study and original research question?
(Please note that you should approach this analysis like you would an essay test. Use key terms and concepts, and define them in your own words, to demonstrate your understanding of the material. Be as detailed as possible to showcase your learning from the module.)

 

2. (15 Points) Previous research shows that students that take transfer level math and English within their first year of college are more likely to finish their degree. Data was collected from 40 students currently enrolled in a Behavioral Statistics course at ABC College, in order to assess at what point students take Behavioral Statistics within a program. The program hopes to determine if the department should be recommending Behavioral Statistics within their other courses to promote earlier completion and encourage students to complete their degrees with fewer units.

The following data was collected where P represents the participant number for each student, and the classes column reflects how many courses they have successfully completed before taking Behavioral Statistics:

Student (denoted Pn) Classes Student (denoted Pn) Classes
P1 1 P21 3
P2 6 P22 3
P3 3 P23 2
P4 3 P24 7
P5 3 P25 6
P6 4 P26 4
P7 4 P27 4

Module 3
SPSS Exam
Z – Scores and Normal Distribution
1. (10 points) Please choose ANY interval or ratio variable from your student survey.
a. What research question could be answered with that data?
b. Set up the variable in SPSS and copy the data from the survey into SPSS and do the following:
• Use SPSS to convert the scores to z-scores. Create a frequency table and a graph for BOTH the raw scores and the Z scores
• Calculate the mean, mode, median, variance, range, and standard deviation, for BOTH the raw scores and Z scores of the selected variable.
• Copy and paste your data for the Z scores as well as the requested output directly into the document.
c. Provide a narrative description of the raw data followed by a general description of the Z score. What patterns do you see in the data based on the distribution?
d. If you did not already address these points in your narrative description, please answer the following questions about your data analysis:
• Present and Explain Measures of Central Tendency including the Mean, Mode, and Median for both the raw data. What do these terms mean?
• Are there outliers? Given the distribution of the data, which measure is best to report and what conclusions can you draw for the research question and variable presented?
• Z-scores – What are the mean and standard deviations for the Z-scores? Are these normal? If so, why?
• In terms of Z-scores how do we define outliers? Based on the Z-Scores, what scores are outliers?

3. (15 Points) Please use the data on AGE in the student survey to run a hypothesis test comparing your individual age to the rest of the sample based on all the data points for AGE included in the student survey. Outline each of the steps of the hypothesis test, and write up a results section in APA format consistent with the template provided.

4. (15 Points) For this question, you will use the MATH ANIXETY data used above. Assuming an average student population mean of 7 for MATH ANXIETY, and a standard deviation of 5, assuming α = .05, conduct a two tailed hypothesis test comparing the data from the student survey on our sample of students to the general population. Outline each of the steps of the hypothesis test, and write up a results section in APA format consistent with the template provided.
