Covariance and correlation

Animal deaths, especially from anthropogenic causes, are valuable indicators of ecological and conservation problems that span a particular population (Collins 2011). Deer mortalities are no exception to this rule of thumb, as deer-vehicle collisions (DVCs) are a growing problem in the US and reflect the displacement of deer populations. Over 1 million DVCs occur in the US annually and result in the loss of human life, human injury, and considerable financial costs resulting from the vehicle…

and 2, provide weak positive linear relationships between the amount of time spent participating in extracurricular activities when compared to campus common assessment data. Table 8 depicts the weak positive relationship as it pertains to the correlation coefficient, ranging from +.20 to +.29, for a number of the comparisons between amount of time spent participating in extracurricular activities when compared to CCA results. When exploring the scatterplots further, Figures 1 and 2, the data…

A study was conducted to measure an individual’s attitudes towards homosexuality, attitude scales have been devised from Larsen et al in 1980 to LeMar and Kite’s 1997 attitude scale, to reflect modern day attitudes towards homosexuality a study was conducted using a new scale as the old one is outdated, using this new scale and additional study was conducted into the attitudes of an individual and the participant’s levels of religiosity to test the relationship between the two topics. Various…

Avdic, 2011). Discipline and organisation of conscientious students (Komarraju, Karau, & Schmeck, 2009) enable effective learning methods, especially the two learning styles of methodical study and synthesis analysis that have the highest positive correlation with both conscientiousness and GPA. These two learning styles complement the traits of conscientious students which when paired with motivation, result in the highest academic performance of all five personalities (Komarraju, Karau,…

self-esteem which were the Big Five Inventory (BFI) and the Rosenberg Self-Esteem Scale. The relationship between the two variables was statistically analyzed using the Pearson’s r correlational test. This study hypothesized that there is a positive correlation between extraversion and self-esteem. The results showed that extraversion had a non-significant relationship with self-esteem thus failing to reject the null hypothesis. Introduction…

psychologists is correlation. Correlations provide data that enables psychologists to answer questions that have not been answered before. Correlation method is defined as “A research method used to examine relationships between variables, which are expressed in the form of a statistical measure called a correlation coefficients” (Nevid,201,p24). Unlike an experiment where one variable is dependent and the other is independent, both variables in a correlation remain constant. For each…

the “blood” after 60 minutes a calibration curve had to be created by making up seven different solutions of eosin (11,25 μg ml-1) and water to compare it against their absorbance that was calculated in a spectrophotometer. Figure 1 shows this correlation. It is clearly evident that the higher the concentration of eosin in a test tube, the higher the absorbance of that test tube will be. It shows that absorbance is directly proportional to concentration. This…

individual well-being and happiness. Due to this increase there have been multitudes of theories and studies conducted to determine appropriate interventions to assist individuals well-being. This essay will focus on gratitude intervention and its correlation with well-being. This essay will use empirical evidence to prove the link between gratitude and subjective well-being. This essay will also give clear insight into intervention assessment, test scoring, as well as discussing the detailed…

self-defeating humor score, the lower the usage of humor as a coping strategy. However, the results of the present study do not support the idea of a negative correlation. Instead, there is a weak, but significant positive correlation between self-defeating humor and the use of humor as a coping strategy, rather than the negative correlation between the two measures. Based on these results, if an individual’s score on the HSQ is high for self-defeating humor, then they also have a high score…

In the following two studies, Vrij and Mann (2001) and Mann, Vrij, and Bull (2004), respectively, researched police officers abilities to detect deception in real-life, high-stakes scenarios. They also looked at the behavioural cues which were used to come to these conclusions. In the first study by Vrij and Mann (2001), participants were comprised of 52 police officers in the Netherlands, 28 male and 24 female. The officers had an average age of 30, around 9 years of service, and rated…
