Description
SPSS HOMEWORK:FREQUENCY TABLES,HISTOGRAMS,AND BAR CHARTS
ASSIGNMENT INSTRUCTIONS
OVERVIEW
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 commonly used statistical software packages in behavioral science settings, both academic and professional.
INSTRUCTIONS
To access the homework problems for this assignment, please download the SPSS
Homework: Frequency Tables, Histograms, and Bar Charts Template document
linked on the SPSS Homework: Frequency Tables, Histograms, and Bar Charts
Assignment page.
This assignment includes two problem sets that contain research scenarios and related
questions, as well as one integration question.
For each scenario, you will create a new SPSS data file with the data from the problem
scenario. ALL variable names in your SPSS data files must include your initials, so that
they show up in your SPSS output and graph. For example, for someone with the initials
ABC creating a variable of memory scores, the variable could be named
“ABC_mem_scores” or “Mem_Scores_ABC”, etc.
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.
Please review the SPSS Homework Tutorial in this module for directions on how to enter data in SPSS and use it to produce the final product for your assignment.

SPSS HOMEWORK: FREQUENCY TABLES, HISTOGRAMS, AND BAR CHARTS
TEMPLATE
Problem Set 1: A social psychologist is interested in attitudes toward technology among people
over 65 years of age. She develops a scale where a lower score indicates a less positive attitude
and administers it to 15 people over 65. The results appear in the table below. Remember to put
your initials within any and all variable names.

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 scale. Paste the frequency table here: (8 pts)
2. How many people have a score of 14? (5 pts)
3. What percent of people have a score of 12? (5 pts)
4. Which score has the highest frequency in the table? (5 pts)
5. Using the same data, create a histogram in SPSS to show the distribution of the scores.
Paste the histogram here: (7 pts)

Problem Set 2: An undergraduate Psychology student wants to examine the number of
applications to doctoral programs in different subfields of Psychology. He collects data from a
sample of schools in the US. He compiles the chart below. (The data here are based on real data
taken from the web site of the American Psychological Association
(https://www.apa.org/education/grad/survey-data/2016-report.pdf).
Enter the data in a new SPSS file. When creating the Program variable, be sure that the type is
set to “String” in the Variable View so that the names will show up on the graph. Remember to
put your initials within any and all variable names.

1. Using the data in the table above, set up a data file in SPSS and create a bar chart that
shows the number of applications for each subfield. (8 pts)
2. Which three subfileds have the highest number of applications according to the graph? (5
pts)
3. Which level of measurement (nominal/ordinal/interval/ratio) is the variable “Subfield?
Support your answer with information from the course materials (textbook or
presentations). (5 pts)
4. Which level of measurement is the variable “Number of Applications”? Support your
answer with information from the course materials (textbook or presentations). (5 pts)
Integration: Answer the following question based on Problems 1 and 2 above and what you
have learned from readings and presentations this week.
1. Explain why it is appropriate to create a histogram for the Attitudes Toward Technology
data, but a bar chart for the number of applications per subfield. (7 pts)
