Data Collection

Data Collection Report for Group Project: Growlithe Group

Because of our very busy schedules, each of us depended on ourselves to get data collected from the assigned sections. Xxxx did section one, Xxxx Xxxxxxx did section two, Xxxxx and Xxxxx did section three, Xxxx Xxxxxxxxx did section five, and I did sections four and six.

After copying the sexes and birth/death dates, each section’s headstones were numbered with two sets of numbers. One set was for females and the other for males. After this, we each took the total number of each set individually and multiplied by .05. This gave us how many headstones to use in the random selection. Next, each of us chose a line from Table A to pick headstones randomly. We did the numbers in pairs of three: (line 101: 192 239 503 etc) until the number of headstones needed was satisfied. After doing this process, the ages of death were added up, and then divided by the number of selected headstones to get the male/female averages.

The data collection process may not be 100% accurate, though, because we have to allow for human error in the recording process.

Our samples of headstones are not a very accurate representation of the population due to the fact that some of the headstones were unreadable and others either had no birth date, no death date, or both. But we have to include them as not to seem bias. To ensure accuracy of the data collection, however, we have decided to make up for any of those headstones possibly being picked during random selection by just randomly pick others in their places. Another problem that has arisen is that one group member’s work was done, but not comprehensible, therefore section one is in the process of being redone also to ensure better accuracy. Section three, is unavailable because of Xxxx’s sickness. The integrity of the data collected thus far has answered our question with strong precision and accuracy. The questions being: did the males live longer than females at Mt. Vernon Cemetery, and is the average age of death between 50 and 70 for males and between 60 and 80 for females? The stem-leaf plots will give you an idea of the data analysis to come to our questions in full with an exception to Sections 1 and 3 for now.
