Summary and
Descriptive Statistics
There is
often the requirement to evaluate descriptive statistics for data within the
organization or for health care information. Every year the National Cancer
Institute collects and publishes data based on patient demographics.
Understanding differences between the groups based upon the collected data
often informs health care professionals towards research, treatment options, or
patient education.
Using the
data on the "National Cancer Institute Data" Excel spreadsheet,
calculate the descriptive statistics indicated below for each of the
Race/Ethnicity groups. Refer to your textbook and the Topic Materials, as
needed, for assistance in with creating Excel formulas.
Provide the
following descriptive statistics:
Measures of
Central Tendency: Mean, Median, and Mode
Measures of
Variation: Variance, Standard Deviation, and Range (a formula is not needed for
Range).
Once the
data is calculated, provide a 150-250 word analysis of the descriptive
statistics on the spreadsheet. This should include differences and health
outcomes between groups.
APA style
is not required, but solid academic writing is expected.
