¶ … Sleep Deprivation
As shown in the variable table, the two relevant variables for determining how sleep affects abilities are Hours (the number of hours each participant has gone without sleep) and Errors (the number of errors each participant made in their arithmetic test). Both are quantitative variables; Hours is the independent variable in this study, and Errors is the dependent variable. This particular study has a sample size of ten -- ten subjects were examined during the course of the research. Analysis of the raw data collected from these subjects was conducted using the spreadsheet and statistical program Microsoft Excel.
By highlighting the two columns of relevant data and using Excel's built-in functions, a scatter plot was created. The arrangement of the data in the plot visually suggests a linear relationship, which makes further regression analysis appropriate. Excel was thus used to add a trendline to the scatter plot, and to display the equation that fits this line. The line closely matches the raw data points in the scatter plot, with few data points...
The regression equation is y=0.475x+3, where y is the number of errors (the dependent variable) and x is the number of hours each participant went without sleep (the independent variable). The coefficient of x shows a relatively gradual increase in the number of errors as the number of hours without sleep increases. Using this equation, the number of errors that would be expected after 10 hours without sleep is 0.475(10)+3=7.75 or about 8 errors. At 4 hours without sleep, there would be 0.475(4)+3=4.9 or about 5 errors. A greater variance in x range than y range would likely indicate a curved relationship if any. The strength of the relationship between hours without sleep and errors on the test, as can be seen from the correlation coefficient, is quite high).
Cheese, Please!
For this study, as can be seen in the variable table, Sodium (the amount of sodium per slice of each brand of cheese) and Calories (the number of calories per slice of each brand of cheese), are the two relevant variables, both of which are…
Sleep deprivation is frequently a direct result of the need for intensive care, constant surveillance and monitoring that combine to limit the opportunities for uninterrupted sleep in the intensive care unit (ICU). The problem is multifactorial, with patients' chronic underlying illness, pain, pharmacological interventions used for the treatment of the primary illness, as well as the ICU environment itself have all been shown to be contributing factors to the process
Sleep Deprivation and Expert Witnesses Introduction (the issue(s) presented and purpose of your paper) The paper will focus on the links between sleep deprivation, false confessions and torture. The paper is written in the context of Federal Rules of Evidence 702 and the testimony of an expert witness. The focus lies in the fight between experts on each side (defense and prosecution) and how an expert witness can provide clarity regarding a
Sleep Deprivation on the Brain Studies on sleep deprivation continually display an inconsistent (negative) effect on mood, cognitive behaviour, and motor function as a result of a rising propensity for sleep as well as the destabilization of the wake condition. Unique neurocognitive domains such as executive attention, functioning memory, and conflicting higher cognitive behaviours are specifically apt to loss of sleep. In human beings, functional neurophysiological and metabolic studies prove
Sleep on Life Satisfaction and Cognitive Function Popular literature is replete with articles presenting evidence of the many harmful effects of sleep deprivation and the general consensus is that modern society works too much and sleeps too little. To be accurate, many empirical studies do exist that demonstrate the ill effects of insufficient sleep (Shekleton, 2010). Where these studies once predominantly emanated from the field of applied psychology -- in
Sleep Disorders / College Students The Prevalence of Sleep Disorders in College Students: Impact on Academic Performance There are a number of reasons that college students experience sleep disorders. A common problem is sleep deprivation and resulting excessive daytime sleepiness (EDS). Both biological and social factors can be at the root of the problem, the consequences of which may be serious. The purpose of Gaultney's study was to look at sleep disorders
Neonatal Sleep Neonatal nurseries are the only alternative environment to a human womb that is offered to a preterm infant . The development of these nurseries and its accessories has now opened a new era in the management of these preterm infants .These nurseries by virtue of their sophisticated machines and experienced care givers are now offering a better chance of survival to these fragile infants .These preterm infants are now
