DESCRIPTIVE STATISTICS
Descriptive Statistics: An Analysis of Sample Demographics
In this particular task the health of stuff nurses of a large hospital is analysis using SPSS and
the key findings of their health attributes are reported. At first the data given in the excel file is
imported in SPSS and the variables are assigned to appropriate types. There are all three types of
variable in the entire dataset of 102 instances which are scaled numeric, nominal and ordinal
variables. The variable education, BMI group, exercise level are ordinal variables and smoking
history and diabetes status are nominal variable (George & Mallery, 2016).
Demographic Analysis
Demographic analysis is performed with the data given in excel file. A detail
descrition is given in the second spreadsheet of the excel file. The dataset has 2 missing instances
which are removed automatically when performing analysis in SPSS. Now, at first descriptive
statistics of the variable is found using SPSS and then the confidence interval of the Body Mass
Index of nurses is found which indicates health status of the nurses in the hospital.
Results and discussion:
Now, descriptive statistics of each variable excluding patient ID is calculated in SPSS as
patient ID is assigned randomly and thus statistics of patient ID has no importance. Now, for
scaled variables the different measures of central tendency and dispersion are calculated (George
& Mallery, 2016). However, for ordinal and nominal variables those measures are not
meaningful and thus the categories of those variables are represented in percentages.
