Suppose a researcher is interested in the effectiveness of a new novel talk therapy technique in reducing overall depression as identified via score report on the geriatric depression scale (GDS). In order to carry out this hypothesis, the researcher gathers a SRS of participants in the program and performs the GDS test prior to, and after initiation of the new therapy technique (on the same subjects). The following table summarizes the results: GDS Score Prior to intervention GDS Score Following...

The average waiting time for a patient at an El Paso physician’s office is just over 29 minutes, well above the national average of 21 minutes. In fact, El Paso has the longest physician’s office waiting times in the United States. In order to address the issue of long patient wait times, some physician’s offices are using wait tracking systems to notify patients of expected wait times. Patients can adjust their arrival times based on this information and spend less...

A clinic specializing in eating disorders would like to evaluate the effectiveness of a nutritional training program on binge eating disorder (BED). A psychologist was hired to conduct a small study to examine the potential effect of nutritional training on number of binges per month. The psychologist recruited 10 patients in the clinic to participate in a nutritional training program and 12 patients in the clinic with similar demographics who do not participate in the nutritional program. Afterward, all participants...
