SOCI 332 Assignment 2 Tests of SignificanceAssignment 2: Tests of Significance
Throughout this assignment you will review mock studies. You will needs to
follow the directions outlined in the section using SPSS and decide whether there
is significance between the variables. You will need to list the five steps of
hypothesis testing (as covered in the lesson for Week 6) to see how every question
should be formatted. You will complete all of the problems. Be sure to cut and
past the appropriate test result boxes from SPSS under each problem and explain
what you will do with your research hypotheses. All calculations should be
coming from your SPSS. You will need to submit the SPSS output file to get
credit for this assignment. This file will save as a .spv file and will need to be in a
single file. In other words, you are not allowed to submit more than one output file
for this assignment.
The five steps of hypothesis testing when using SPSS are as follows:
1. State your research hypothesis (H1) and null hypothesis (H0).
2. Identify your confidence interval (.05 or .01)
3. Conduct your analysis using SPSS.
4. Look for the valid score for comparison. This score is usually under ‘Sig 2-
tail’ or ‘Sig. 2’. We will call this “p”.
5. Compare the two and apply the following rule:
a. If “p” is < or = confidence interval, than you reject the null.
Be sure to explain to the reader what this means in regards to your study.
(Ex: will you recommend counseling services?)
* Be sure that your answers are clearly distinguishable. Perhaps you bold your
font or use a different color.
This assignment is due no later than Sunday of Week 6 by 11:55 pm ET. Save
the file in the following format: [your last name_SOCI332_A2]. The file must
be a word file.

Open SPSS
Enter the number of activities of daily living performed by the depressed clients
studied in #1 in the Data View window.
In the Variable View window, change the variable name to “ADL” and set the
decimals to zero.
Click Analyze Compare Means One-Sample T test the arrow to move
“ADL” to the Variable(s) window.
Enter the population mean (17) in the “Test Value” box.
Click OK.
1. Researches are interested in whether depressed people undergoing group
therapy will perform a different number of activities of daily living after
group therapy. The researchers have randomly selected 12 depressed clients
to undergo a 6-week group therapy program.
Use the five steps of hypothesis testing to determine whether the average
number of activities of daily living (shown below) obtained after therapy is
significantly different from a mean number of activities of 17 that is typical
for depressed people. (Clearly indicate each step).
Test the difference at the .05 level of significance and at the .01 level (in
SPSS this means you change the “confidence level” from 95% to 99%).
As part of Step 5, indicate whether the behavioral scientists should
recommend group therapy for all depressed people based on evaluation of
the null hypothesis at both levels of significance.
