PSYC 354 Page 1 of 6 SPSS H OMEWORK : F REQUENCY T ABLES , H ISTOGRAMS , AND B AR C HARTS A SSIGNMENT I NSTRUCTIONS O VERVIEW This assignment is designed to increase your statistical literacy and proficiency in creating and interpreting frequency tables, histograms, and bar charts. You will be creating these in SPSS, using data that are related to specific research scenarios in the behavioral sciences such as psychology, social work, and counseling. A working knowledge of how to summarize and visualize data is fundamental to being able to understand and apply research in your related field to your practice. Additionally, SPSS skills are professionally valuable, as it is one of the most used statistical software packages in behavioral science settings, both academic and professional. I NSTRUCTIONS This assignment includes two problem sets that contain research scenarios and related questions. For each scenario, you will respond to a series of questions asking you to create and interpret either frequency tables, histograms, or bar charts. Paste your SPSS output directly into the homework underneath each relevant question. Type written answers into the document underneath the question to which they relate. This assignment is worth 60 points. Please review the Watch: SPSS Homework Tutorial: Frequency Tables and Histograms in this module for directions on how to enter data in SPSS and use it to produce the final product for your assignment. The scenarios begin on the next page.
PSYC 354 Page 2 of 6 Problem Set 1: The BDI (Beck et al., 1961) is an instrument widely used to assess levels of depression in individuals in a variety of settings. The scores range from 0–63 (whole numbers only). A researcher administers the BDI to a sample of college students. The results appear in the table below. They are entered as 2 columns here to save space (i.e., you will not need 2 columns in the SPSS file). 1. Using the data in the table above, set up a data file in SPSS and create a frequency table to show the frequency of each score on the BDI. Paste the frequency table here: (8 pts) BDISCORES Frequency Percent Valid Percent Cumulative Percent 3.00 1 5.0 5.0 5.0 4.00 1 5.0 5.0 10.0 9.00 3 15.0 15.0 25.0 10.00 3 15.0 15.0 40.0 11.00 5 25.0 25.0 65.0 15.00 2 10.0 10.0 75.0 20.00 2 10.0 10.0 85.0 61.00 2 10.0 10.0 95.0 62.00 1 5.0 5.0 100.0 Valid Total 20 100.0 100.0 BDI Scores 9 10 9 9 11 3 11 20 11 62 15 11 10 4 61 61 20 15 10 11

Which score has the highest frequency in the table? (5 pts) BDI SCORE OF 11 5. Using the same data, create a histogram in SPSS to show the distribution of the BDI data. Paste the histogram here: (7 pts)

PSYC 354 Page 4 of 6 Problem Set 2: The overall livability scores of 12 US cities appear in the columns to the left. The data are based on data taken from the livability calculator at (http://www.areavibes.com/). Enter the data in a new SPSS file. When creating the City variable, be sure that the type is set to “String” in the Variable View so that the names will show up on the graph. (continued on next page) 1. Using the data in the table above, set up a data file in SPSS and create a bar chart that shows the livability rating for each city. (8 pts) City Livability Score Boston Austin Chicago Pittsburgh San Diego Jackson, MS Detroit Miami New York Charlotte Atlanta Seattle 73 83 73 75 80 72 67 71 73 80 78 77
PSYC 354 Page 5 of 6 2. Which three cities have the highest livability scores according to the graph? (5 pts) AUSTIN, CHARLOTTE, AND SAN DIEGO 3. What level of measurement is the variable “City”? Support your answer with information from the course materials (textbook or presentations). (5 pts) THE LEVEL OF MEASURMENT IS NOMINAL, DUE OT HE FACT CITIES ARENT NUMERICAL. 4. What level of measurement is the variable “Livability Score”? Support your answer with information from the course materials (textbook or presentations). (5 pts) THE LEVEL OF MEASURMENT IS NUMERICAL, DUE TO THE FACT OF THE NUMBERS. Integration: Answer the following question based on Problems 1 and 2 above and what you have learned from readings and presentations this week.
PSYC 354 Page 6 of 6 1. Why is it appropriate to create a histogram for the BDI scores, but a bar chart for the livability ratings? (7 pts) It’s important because the Histogram shows not only the total of BDI’S but the graph breaks down the Percentages and which person goes in which category. The bar chart for the cities shows a straight overall number of that particular place. Since the cities are string in value the bar chart best fits because it can display the numerical and nominal values.
