Dat GPA Vs. Level Focused
For past generations, teachers have been telling students to get enough sleep. Everyone to this point believes that sleep is an important factor to stay focused in class. I myself believe that the more hours of sleep you get, the higher level of focus you will get in class. However, to what extent is this statement true? Would level of focusness in class reflect your grades due to the number of hours of sleep you get? To attempt to do so, I will gather some sort of data and formula to calculate its results. Since I am trying to find a relationship with my data, it would make sense if I would use Pearson's correlation coefficient formula. With this formula, I am able to calculate the correlation coefficient. With this data, I am able to see …show more content…
With the survey, I decided to compare three sets of data: Level Focused vs. GPA, Hours of Sleep vs. Level Focused, and Hours of Sleep vs. GPA.To make the math process for convenient, I have decided to convert ranged numbers from my survey questions to single digits. For GPA, I have changed 2.0-2.9 to 2.5, 3.0-3.9 to 3.5, and 4.0+ to 4.2. For hours, I changed 5-8 hours to 6.5 hours, 5 hours or less to 4.5 hours, and 8+ hours to 7.5 hours. To calculate math, I have used the Pearson Correlation Coefficient formula to find r, correlation coefficient and analyze its relationship with the …show more content…
A correlation coefficient is a number that ranges between -1 and 1 and is never greater than 1. If the number is between 0 and 1, there is a positive relation. An example of this would be the more hours of sleep you have, the greater gpa you shall have. If the value is between -1 and 0, then it has a negative relation. An example of this would be the fewer hours of sleep you have, the lower gpa you shall have. Lastly, if the value is neither between -1 and 1 but near or at zero, then it has no relation. In our case, that would mean the number of hours of sleep you have does not have an effect with your

    Amount of Sleep and Gpa in Graduate Students at Ohio

    Amount of Sleep and GPA in Graduate Students at Ohio University Many graduate students may not be receiving enough sleep at night. With increased workloads and responsibilities many students are forced to sacrifice their sleep hours to keep up with the work. This means that students are forced to stay up later and get up earlier. It has been found that lack of sleep can reduce ones mental capabilities like a lack of focus. With graduate students getting less sleep it may be possible that they suffer mentally and see a decline in GPA when compared with someone who receives more sleep. I plan to research whether there is a relationship between the hours of sleep a student gets and his or her GPA. This correlational study involved forty randomly selected people whose hours of sleep were charted and GPA reported. The hours or sleep and the GPA of the students were entered into SPSS 's spread sheet and are shown on the next page.…

    Sleep Is Correlated to Grades

    I investigate students attaining higher grades on exams when they receive proper sleep. I discuss 3 possible hypotheses for the reason of this occurrence: 1) more sleep contributes to greater capability in remembering, 2) rest is necessary for the brain to function at its prime, 3) staying awake and studying the night before leaves you with no energy during the actual exam. I will test hypothesis 2, which will include individuals to have 8 hours or more of sleep or less than 8 to no sleep at all and using EEG method to visualize the brains activity in relation to the amount of sleep and observing the scores received on exams. I would expect that students with at least 8 hours of sleep will receive better marks than those who get little to no sleep.…

    School Hours Persuasive Speech

    Kids have become so stressed because of school that they only see faking sick, skipping, or even hurting themselves to avoid attending their classes everyday. When will public school systems realize that sometimes students cannot take the pressure of receiving near perfect grades to get into a good college that eventually rests on how their entire life will pan out? Even while students are doing well in school, chronic sleep development can cause a decrease in performance. Having your sleep reduced by as little as an hour and a half can impact you greatly. In addition to my previous statement, chronic sleep loss can also severely impact your memory and cognitive development-- your ability to process information. This means that after learning new things all day in school, a student might forget key things the following day.…

    Pros And Cons Of Starting School Later

    Lack of sleep can really take its toll on you and your body in many ways. If you don't get enough sleep it can have a huge impact on your learning ability. When you are too tired in the morning it makes you less attentive during the school day, and it could even cause you to fall asleep during class. (Paksarian, et. al. 1352) The main purpose of going to school is to learn and if you’re falling asleep it’s not doing you any good. Falling asleep in class is just one of the least dangerous effects of not getting enough sleep. Truthfully, if you aren't getting enough sleep it can really effect your health. A lot of students who don’t sleep enough tend to be…

    How Does Sleep Affect Children

    Joseph Buckhalt of Auburn University did a research study to find out how sleep affects kids academically. The kids wore an actigraph when they went to bed, which measures quality and sleep duration, the parents were also told to keep a journal of the times their kids went to sleep and what times they woke up. When they came into school they were to report to a specific classroom where there were other sleep measures and cognitive tests done. The results showed the kids that had less sleep throughout the week had significantly lower scores on the cognitive tests and sleep measures. Another study done by Dr. Avi Sadeh of Tel Aviv University, he gave 77 fourth graders and sixth graders random instructions on either to go to be 30 minutes early or 30 minutes late for three days. Dr. Avi also used actigraphs to measure sleep on the kids. His findings were very similar to that of Buckhalts, although they seem more disturbing. The gap between the sixth graders tests and the fourth graders suggest that a very tired and sleepy sixth grader performs about as well as a well rested fourth grader. Only an hour of sleep affected a child essentially of losing two years of…

    Correlational Research Guidelines

    Your hypothesis might be that there is a positive correlation (for example, the number of hours of study & your midterm exam scores), or a negative correlation (for example, your levels of stress & your exam scores). A perfect correlation would be an r = +1.0 & -1.0, while no correlation would be r = 0. Perfect correlations would almost never occur; expect to see correlations much less than + or - 1.0. Although correlation can't prove a causal relationship, it can be used for prediction, to support a theory, to measure test-retest reliability, etc.…

    Homework-"Such a Frustration"

    For instance from the article “Is Too Much Homework Bad for Kids’ Health” by Sandra Levy, it talks about how students who spend way too much time on homework have more stress and health problems. According to this article the study that was done, more than two hours of homework a night can be counterproductive. Researchers studied 4,317 students from 10 high-performing high schools in higher-middle-class California, according to this study the students there complete a total average of just about 3.1 hors of homework each and every night. According to Pope in this article “The findings address how current homework practices in privileged, high-performing school sustain students’ advantage in competitive climates yet hinder learning, full engagement and well-being”. To most students a lot of homework is pointless homework. For example the researchers found that spending too much time on homework meant that students were not meeting their developmental needs or cultivating other critical life skills. A very important point in this article was that sleep is important too. Reason saying this is that according to the researchers, no matter how much a student studies each day, if that students sacrifices sleep time to study more than normal, then she or he will more likely to have more trouble understanding material taught in class and struggle more on a assignment or text on the next day.…

    Effects of Unhealthy Lifestyle

    Normally, student from university are busy with their assignments, tests, and cocurriculums and this made them lack of time of sleep. Our research also focus on effects of lack of sleep which causes sleep deprivation, emotional and difficult to focus during lecture. Stated by (Zammit et al,1999; Sateria et al,2000; Akerstedt and Nilsson, 2003), poor quality and quantity of sleep are associated with reduced daily occupational function and quality of life. This statement proves that lack of sleep can cause students difficult to focus well during lecture. Besides that, Bonnet and Arand (1995), said that if sleep is reduced by as little as 1.3-1.5 hours in one night’s worth of sleep, the resultant reduction in daytime alertness can be much as 32% and once again previous research proved that lack of sleep can reduce the daily performance. Apart from that, Neckelmann (2007) , found that lack of sleep or insomnia has been found to be a factor in the incidence of anxiety disorders or emotional. Besides that, Akerstedt et al (2002) found that the inability to stop worrying about work during…

    Sleep Deprivation

    It’s proven that restricted sleep in a stimulated classroom led to lower quiz scores, more inattentive behaviors and lower arousal. Due to an impressive workload, sleep disturbances seem especially prevalent in medical students and residents. These studies are conducted to help benefit students, and get them aware of their sleep patterns and the true proficiency to these studies. In addition to air, water, and food, the only other biological necessity our bodies require is sleep (Gregory, Xie, & Mengel, 2004). Sleep is critical for memory consolidation, learning, decision making, and critical thinking (Harrison & Horne, 2000; Mednick, Nakayama, & Stickgold, 2003; Pilcher & Walters, 1997; Smith & Lapp, 1991). Sleep is thus necessary for the optimal operation of key cognitive functions related to academic, and perhaps social, success in higher education.…
