Instructions: For this project, you will be using SPSS to conduct a t-test (Chap 16). Projects should be typed,
not hand-written. Your SPSS output should be copied and pasted into your document; alternatively, you
can attach your output to your answers. Page 2 of this assignment describes the steps to using SPSS.
This study examined the influence of an 8-week program designed to help 24 patients recover from the effects
of a stroke. All subjects were evaluated at the start of the program and after Week 8. The recovery status of each
subject at each time was evaluated using the Barthel Index. The Barthel Index gave a single overall score for
motor function. Higher scores indicate better functional ability.
Subject ID number
Barthel Index score prior to therapy. Scaled from 1 to 100, where higher
values indicate more functionality.
Barthel Index score after the therapy. Scaled from 1 to 100, where higher
values indicate more functionality.

Use the SPSS data file Project 4 data set to conduct a dependent samples t-test using SPSS to determine if
therapy helps stroke patients. Your educated guess is that therapy WILL help people. Assume a two-tailed test
with an alpha of .05.
1. State Ho statistically.
State HA statistically.
2. Report your degrees of freedom and your critical t-value(s). In other words, using your t-table what
critical value does your obtained t-value have to surpass in order for the two samples to be significantly
different?
3. What type of dependent samples design is this? Why? (HINT – look at the lecture notes describing the
three types of dependent samples designs).
