Central Tendency Assignment Instructions
A neuropsychologist who works with clients over 60 years of age administers the Dementia Severity Rating Scale (DSRS; Clark and Ewbank, 1996) to the caregivers of 20 clients. On the DSRS, lower scores indicate a lack of, or low severity of, dementia symptoms; while higher scores indicate more severe dementia symptoms. The scores are contained in the table below.

Using the data in the table above, set up a data file in SPSS and create a table of descriptive statistics using the “Explore” command. Paste the table here: (8 pts)
Using the same data, create a histogram showing the distribution of DSRS scores in the sample. Paste the histogram here: (7 pts)
List the mean and the median for DSRS scores. (4 pts)
Based on the information in numbers 1-3, which measure of central tendency would you use to describe this data set? Support your answer with material from the presentations and/or reading this week. (6 pts)
Locate the outliers in the data set. Based on your knowledge of DSRS scores, what would your recommendation be for the caregivers of the patients with these outlying scores? (5 pts)
