Spearman's rank correlation coefficient

The value of the correlation coefficient is found to be insignificant at 5 per cent level. Secondly, the correlation between ROI and QR is 0.90 which is also found to be insignificant at 5 per cent level. It reveals that there is no correlation between the two variables. It is evident from these two ratios that the lower the company's margin of safety to the short term creditors, the greater is the profitability of the concern. Thirdly, the correlation coefficient between ROI and WCR is…

According to these studies, correlations between the engagement and burnout scales range between -.40 and -.60, while the correlations for absorption on the MBI scales are occasionally lower and the correlations for lack of efficacy on the UWES scales are occasionally higher. Engagement is negatively associated with burnout; however, in terms of professional efficacy,…

Procedure The study will be submitted to Northern Illinois University’s Institutional Review Board for approval. Once approval is granted and a middle school has agreed to participate in the study, a letter will be sent home to parents explaining the study and that their consent is required for their child(ren) to participate. All students whose parents return the consent form will be discussed among school staff in order to make pairs. Teachers, social workers, and paraprofessionals will…

Game. Knowing from experience you can spend over 1,000 dollars on just tickets for a regular season game. I feel like payday and sporting events don’t truly correlate. Through this semester I’ve learned that there is only a very limited positive correlation between changes in income and changes in consumption. So, an increase in cash doesn’t mean that they will spend more at games but they will because of their love for the game and the…

Statistics Worksheet Part A Question 1 a) Below is the calculation for the Pearson product-moment correlation coefficient between the total number of problems correct and the attitude toward test taking. Total no. of problems correct (out of a possible 20): X Attitude toward test taking (out of a possible 100): Y (X - X ̅)² (Y - Y ̅)² (X-X ̅)(Y-Y ̅) 1 17 94 1.96 204.49 20.02 2 13 73 6.76 44.89 17.42 3 12 59 12.96 428.49 74.52 4 15 80 0.36 0.09 -0.18 5 16 93 0.16 176.89 5.32 6 14 85 2.56 28.09…

Many herbicides and pesticides are thought to be involved in teratogenic, or embryonic development disturbing, mechanisms. Therefore it is important to study the effects of these chemicals on humans and wildlife in the event of contact or contamination. Case-Control Study of Maternal Residential Atrazine Exposure and Male Genital Malformations by Agopian in 2012 is one study that examines an herbicide, atrazine, in relation to birth defects of male genital development. Atrazine is one of the…

sample size. With a larger sample size, it is possible that the HAI would have a more significant effect on mood. According to a literature review completed in 2001 by Allen, Shykoff, and Izzo, previous research suggests that HAI has a positive correlation on an individual’s mood state. However, there are no findings on direct effects on mood. Rather, other factors such as stress reduction, increased happiness and decreased aggression may cause an increase in an individual’s mood (Allen, Shykoff…

Introduction: The purpose of this study is to see if there is a link between the birth weight and gestation of newborn babies with smoking mothers and non- smoking mothers. The significance of this investigation is to find a relationship between the two as it might help with health benefits. The features in the investigation are the relationship between the two sets of data between the birth weight and the gestation period of smoking mothers and non-smoking mothers. Part A: The median for the…

Description of Data and Descriptive Statistics A wide variety of data was collected for this article, some of which are discrete variables, such as Sex, Marital status, Rank, and Working spouse. All of these were given a score based on a nominal scale, and were then categorized accordingly (e.g. Sex is 1 = male, 2 = female or Rank is 1 = managers, 2 = employees). Other discrete variables included education level and dependent children which were based on the use of an ordinal scale.…
