Question

A clinician was interested in exploring functionality in patients following a stroke rehabilitation program. Participants were recruited through the rehabilitation unit at Providence Care Hospital. Functional status was evaluated at baseline (immediately following stroke), and 8 weeks later. Patients’ functional outcomes were rated on the following 5-point scale: 1 – poor, 2- fair, 3 – moderate, 4 -good, 5 – excellent. The clinician wants to know whether patients improved their functioning over the 8-week period.

1. Under the heading “Results” present your findings (i.e., what you found).
Include at least one measure of central tendency and variability. An assumption check
(describe what you did and what you found, as needed), check for potential outliers,
and present the findings of your inferential test (i.e., your critical value and p value), as
appropriate.
