The Relationship between amount of sleep and reaction time

In addition, there have been many catastrophic events in the world caused by lack of sleep or fatigue in certain situations. These include the disaster of Coherency, the Challenger explosion In 1986 and the Exxon Valued oil spill, many claim, were caused by lack of sleep and fatigue. The employees at Coherency were overworked, working 13 hours or more. The pilots of the Challenger had a significant lack of sleep and the oil spill caused by the workers working over 22 hours per day. Furthermore, these catastrophic events are all that could be affected or prevented with a quick reaction time.

Therefore, could the fatigue and lack of sleep have led to slower reaction times causing these events to occur or was it another variable that the fatigue caused? I wonder if there is a relationship between amount of sleep and reaction time. Plan: To find out the relationship between amount of sleep and reaction time, if there is one, I will be using two different type of investigation. Firstly, I will be doing some of the investigation myself by taking a sample from my year group and having them complete a test.

In addition to that, I will also be getting results from other studies, Investigations and reports on the same experiment as the results would be more reliable and varied. For my own Investigation, since I am comparing, It Is difficult to have certain independent or dependent variables. However, since I am seeing how amount of sleep affects reaction time, as my independent variable, I will use the amount of sleep measured in hours and I will be using the reaction time measured in seconds. I will obtain the amount of sleep by asking the people within the sample and I will get the reaction time by having the sample take a free online test.

For this investigation, I will be using convenience sampling since the investigation has a very small time limit and I will not have any resources available to investigate on a larger sample or to do sample which is outside of this sample. Therefore these results are quite unreliable since It Is only done on a very small group and It Is only convenience sampling so It only takes Into account a very small group of people in a certain location. This Is why I will also be using other Investigations, papers and studies to get more reliable and accurate information.

I will have a sample of 15 people from etc. To find more reliable, accurate and more varied data. Once I have collected the results, I will firstly create a table out of the raw information to simply take down the results. Then, I will create a processed data able to make it easier to create graphs. Then I will work out averages for the reaction times and amount of sleep making them into box and whisker plots. Then, I will create a scatter graph to compare both my variables. I believe that the results will be that the amount of sleep has a very large influence over one's reaction time.

This selection was purely reliability and credibility of the source as the 2 most credible and reliable sources were chosen for the data and information. The first source was the paper "Effect of Total Sleep Deprivation on Reaction Time and Waking EGG Activity in Man" by the American Sleep Disorders Association and Sleep Research Society, written by l. Lorenz, J. Ramose, C. Race, M. A. Guava and M. Coors-Caber. The second paper was by Mitch Leslie for the Stanford report with the name "Sleep impacts reaction time as much as alcohol. Both of these sources gave information such as averages, graphs and conclusions with some analysis but did not give the raw data. Therefore, some of this processed data could be misleading and could be biased. In addition, the data that these sources give are quite different compared to the data given from my investigations. This would mean that my results are probably unreliable as it was conducted on a very small group, none of the variables were changed so there was not much variety and the results were mostly inaccurate.

In addition, there are some missing values especially for the time some people went to the estimated hours of sleep they had gotten. I will treat this as all the other values although if they seem like outliers on a graph, it would be because they are inaccurate. To analyses, I will group the data and information by source treating them differently. Overall, I believe that I have enough data to analyses and to create a inclusion since I have the data I have collected and the information from the other studies.
