Sample size for a given confidence level and margin of error (proportions). Poll articles. Hypotheses tests for a mean, and differences in means (independent and paired samples).

Iterations of analysis eliminated data points that were listed as “unusual observations,” or any data point with a large standardized residual. After 5 iterations, the analysis showed improved residual plots. Randomness in the versus fits and versus order plots means that the linear regression model is appropriate for the data; a straight line in the normal probability plot illustrates the linearity of the data, and a bell shaped curve in the histogram illustrates the normality of the data.

In the fall semester of 2016 at Culver-Stockton College, I plan on conducting a correlational research study between the hours of sleep a person gets at night and how it affects their grade point average. This study will include all current Culver-Stockton College student athletes that are enrolled as full time students that live on campus. These students will be asked to fill out a survey questioning what activities that they are involved in on campus as well as if they have a job or not. The activities include what sport they are a part of and if they are involved in Greek life also. Other questions that will be asked are how many hours of sleep do they get at night in addition to how much time they spend on homework at night. Students will be asked how many hours a week do they have practice and how long they stay up. The reason these student

Sleep affects grades in more ways than one or two or even three. It affect how people feel, think, and act (Gruber,2013). This states that people that have less sleep behave differently than people that get the recommended amount of sleep for their age.They may be more likely to have mistakes in a class or job. They might even act different than they usually do. Sleep also has an affect of no motivation or effort in the work they do (Gruber,2013). This is important because this tells that the person that does not get enough sleep does not have much motivation or effort they put in to the work they perform.People with motivation tend to do things better than people that have none.

The degree of freedoms was 9 and the significance level was 0.05. For these conditions, the chi-square value must be above 16.92. The test statistic provided no convincing evidence that the

Correlation between Q10 What is your cumulative Grade Point Average at Kaplan University? and Q11 How many hours do you spend on school work each week? is: 0.27817234

With a P-value of 0.00, we have a strong level of significance. No additional information is needed to ensure that the data given is accurate.

Weaver from Oklahoma State University. According to the authors “the purpose of the present study was to determine if sleep deprivation and/or poor sleep quality in a sample of non-depressed university students was associated with lower academic performance” (Gilbert, Cameron. 295). The study was also made to determine the relationship between sleep deprivation, sleep quality, and academic performance (Gilbert, Cameron. 298). It was hypothesized that by the end of the study, participants who had higher levels of sleep deprivation and poorer sleep quality would have lower academic performance (as indicated by grade point average [GPA] and course incompletions—drops, withdrawals, and incompletes) than participants with little sleep deprivation and good sleep quality (Gilbert, Cameron. 298). By the end of the study, the authors discussed the results in the following narration:

Both these findings are statistically significant as indicated both by the extremely low P Value (<2.2e -16 for both Figure 1 and Figure 2), as well as the T-Statistic which in both cases does not fall between -1.96 and 1.96. In technical

Research plays a major role in psychology, which research is understood through statistics. Psychologists depend on research to understand theories and to understand how people behave, think, and feel. Research needs to be organized to be understood by psychologists; therefore statistics help organize the information and make the connection between the research and group of people. A strong connection exists between research, statistics, and psychology, which helps others understand how, parts of psychology because the information is broken down. “Psychologists use statistical methods to help them

The mean for group one (Juniors) was 7.61and the standard deviation was 1.08. 7.61(1.08) group two (Seniors) the mean was 8.00 and the standard deviation was 1.30. 8.00(1.30) with a level of significance of .05.
