PSYC 354
SPSS HOMEWORK: TESTING DATA FOR NORMALITY ASSIGNMENT
INSTRUCTIONS
OVERVIEW
This assignment is designed to increase your statistical literacy and proficiency in summarizing,
visualizing, and interpreting variability within data sets. You will work within 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: Testing Date for Normality Template document linked on the SPSS
Homework: Testing Date for Normality Assignment page.
Download the file titled “SPSS Homework Data File”. It is an SPSS data file that
contains a selection of data from the American Time Use Survey. This survey is
conducted by the US Bureau of Labor Statistics and collects information on the amount
of time people report spending on different daily activities, from child care to work to
leisure. This file contains data from the year 2022.
The file contains the following variables:
o EATING_DRINKING: Time spent eating and drinking (minutes per day)
o SLEEPING: Time spent sleeping (minutes per day)
You will use the information in this file to respond to a series of questions asking you to
create and interpret various tables and charts in SPSS. 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: TESTING DATA FOR NORMALITY TEMPLATE
Problem Set 1:
1. For the “EATING_DRINKING” variable, using the “Explore” command, test the data for
normality (as shown in the SPSS tutorial) by performing the following steps:
a. Create a table of descriptive statistics for this variable. Paste the table here: (6 pts)
b. Run a Kolomogorov-Smirnov/ Shapiro-Wilks test for this variable. Paste the table
here: (6 pts)
c. Create a “Normal Q-Q plot” for this variable. Paste the table here: (6 pts)
2. Create a histogram for the “EATING_DRINKING” variable. Paste the histogram here: (6
pts)
3. In several sentences, discuss whether the daily minutes of eating and drinking is normally
distributed in this sample. Justify your answer using information from numbers 1 and 2
above. (6 pts)
Problem Set 2:
1. For the “SLEEPING” variable, using the “Explore” command, test the data for normality
by performing the following steps:
a. Create a table of descriptive statistics for this variable. Paste the table here: (6 pts)
b. Run a Kolomogorov-Smirnov/ Shapiro-Wilks test for this variable. Paste the table
here: (6 pts)
c. Create a “Normal Q-Q plot” for this variable. Paste the table here: (6 pts)
2. Create a histogram for the “SLEEPING” variable. Paste the histogram here: (6 pts)
3. Some might argue that the amount of sleep people report is normally distributed. Based
on careful evaluation of ALL of the data in numbers 4 and 5, would you agree or disagree
that minutes of “Sleep” is normally distributed in this sample? Support your answer with
information from the data and the reading/presentations this week. (6 pts)
