As a healthcare professional, you will work to improve and maintain the health of individuals, families,
and communities in various settings. Basic statistical analysis can be used to gain an understanding of
current problems. Understanding the current situation is the first step in discovering where an
opportunity for improvement exists. This project will assist you in applying basic statistical principles to
a fictional scenario in order to impact the health and wellbeing of the clients being served.
You are currently working at Grady Memorial Hospital in the Infectious Diseases Unit. Over the past few
days, you have noticed an increase in patients admitted with a particular infectious disease. You believe
that the ages of these patients play a critical role in the method used to treat the patients. You decide to
speak to your manager and together you work to use statistical analysis to look more closely at the ages
of these patients. You do some research and put together a spreadsheet of the data that contains the
following information:

Client number
Infection Disease Status
Age of the patient
You need the preliminary findings immediately so that you can start treating these patients. So let’s get
to work!!!!
The data set consists of 60 patients that have the infectious disease with ages ranging from 35 years of
age to 76 years of age for Grady Memorial Hospital.
