Linear regression
In conversations with her patients, a physical therapist notices that patients who are on
Workman's Compensation and have supportive supervisors, eager for them to return to work,
have more positive outcomes in rehabilitation than those patients whose supervisors have a
negative attitude toward their employee's injury: insisting they not return to work until they are at
100% because if anything less they are "useless to the job".
What type of test could the therapist use to see if these two factors have a measurable
relationship?

Several community health centers across a rural state are gathering data on their pre-diabetic
patients and using A1c levels as a baseline measurement to include patients in a research project.
Three different interventions will be applied.
One group of patients will receive a special diet to follow; the second group will work with
physical therapists on a regular exercise program; the third group will follow the diet and engage
in the exercise.
Which statistical test will be appropriate to use to determine which treatment is most effective in
controlling pre-diabetes?

up to their appointments, to the volume of patients of the previous year, who did not show up to
their appointments, to see if the automated system has proven effective. She is considering other

variables as she reviews the data, but is primarily analyzing the number of "no-show" patients
from last year's quarterly reports to this year's.
Cross-sectional
There are two standard treatments for children with ADHD who display a specific set of
characteristics. One treatment is a cognitive behavioral intervention, and the other is a dietary
and biomedical intervention. Both treatments have equally strong clinical evidence supporting
their efficacy. A researcher proposes a comparison of the two interventions to determine which is
preferable. The children will be randomized to one of two groups: half of the children will
receive the cognitive behavioral intervention and the other half of the children will receive the
dietary and biomedical intervention. Which test is appropriate to determining the preferable
treatment?
The mean (average) length of stay and
The mean number of providers seeing each patient each day
