Critical Thinking
For this artifact I attached a project done for Statistical Methods 1 (MAT-152) wherein we were assigned to select of collection of specific data, categorize it by two groups, randomize the sample, and then analyze select quantitative data. In this case, I chose data on heart attacks from 1993 and grouped it by male and female patients, with the quantitative data being the ages of the patients.
The first goal in this was to give an accurate representation of the selected population. This involved using the stratified random sampling method, with 10 patients from each of the 9 diagnosis codes, from a total population of 12,844 patients. Through using the provided software, I also was tasked with creating a series of graphs to represent the sample visually, which I did my best to do properly and in a clear manner.
My second goal was to come to a clear conclusion based upon the analysis of this sample. Since the groups for the sample were male and female patients, and the quantitative data was the ages of the patients, the focus of this was on the average ages of male and female heart attack patients and the inferences one can make from the different calculations. The conclusion I came to is that the male patients were more likely to have heart attacks at a younger age than the female patients, and patients overall are more likely to have a heart attack between the ages of 50-80 years old.
The objective of this project was to analyze a sample of a data set and draw conclusions about a specific aspect of that sample base on various calculations and graphs. I feel that I accomplished this effectively and made a logical conclusion based on the resulting numbers.
