Bio Lab Report Essay, Research Paper

This survey was done to find and compare the suvivorship curves of people who

died anterior to1945 and after 1945. Many medical progresss have been made in this

state since 1945. We have developed many new drugs, vaccinums, and medical

equipment that have aided in prolonging and salvaging lives of worlds. We have besides

developed many new techniques to prove for diesases and this helps people get the

proper medical attending before the disease gets to the point where it can no longer be

controlled.

I would believe that the general belief of most people is that the survivorship of world

would hold dramatically increased after 1945 because of how far scientific discipline has come in

that clip. The lifetime of worlds throughout history has gotten longer, because of

medical progresss. The deceases of the people studied will most probably non merely be from

disease or illness but other causes, such as war, force, drugs, cars, etc.

Methods & A ; Materials:

We received a data sheet to roll up the information from our findings. The sheet is reversible,

with clean columns to enter the male and female persons and the age of their

decease. The age of decease column is divided into five twelvemonth intervals. One side of the

sheet is to roll up the information for those that died before and in the year1945. The

2nd side is for the information of those that have died after the twelvemonth 1945.

We went to the Cullowhee cemetery to roll up the informations off of all of the headstones in

the cemetary. Since the cemetery is so large and non in exact rows, we had to be certain

that be would non pollute the informations and double the keystones, so we roped off

the subdivisions to be certain non to. When analyzing the keystones, we looked at the

keystone and determined if they were male or female, by the name or markers on the

keystone. Second, we looked at the day of the month of decease to find which category to set

them in. Third, we subtracted the twelvemonth of decease from the twelvemonth of birth

to find the

age of decease. After garnering all of this information, we would tag the appropraite infinite on

the informations aggregation sheet. After garnering all of the information from the headstones, we

totaled the figure of male and female deceases per age categorization, on both pre and

station 1945 information sheets. We besides determined the entire figure of headstones, or deceases

by male and female every bit good as before and after 1945.

Following, we used a 2nd information aggregation sheet to find the per centum of people

survivng and the rate of mortality by age category for both males and females, pre and

station 1945. To find the rate of mortality, we took the entire figure of male and

females who died before and after 1945 and divided the figure of deceases per age

category by the entire figure of people that were born.

To find the per centum of people lasting, we foremost calculated the figure of

people who were still populating or had non died yet. To find this figure, we

subtracted the figure of males and females that died, per age category from the sum

figure of the old deceases. After ciphering the figure of people who were still

alive by age category for pre and station 1945 deceases, I divided this figure into the sum

sum of people who were alive at the beginning. This figure is the per centum of

people lasting. This computation was done for all of the age classes for pre and station

1945 informations.

To visually see the survival per centum of males and females who died before and after

1945, I put this information into graph signifier utilizing Microsoft Excel.

Consequence:

The graphs of the information that I collected on this experiment clearly shows a higher

per centum of survivorship after 1945 for both males and females. In both graphs, it is

shown that females live longer than males and the rate of decease for younger males and

females is much lower after 1945. It is besides clearly shown when comparing the pre and

station informations that people have lived longer and to a greater age since 1945.
