Pearson product-moment correlation coefficient

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scale, to reflect modern day attitudes towards homosexuality a study was conducted using a new scale as the old one is outdated, using this new scale and additional study was conducted into the attitudes of an individual and the participant’s levels of religiosity to test the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…

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…

that showed a statistically significant correlation with the ToM results from the second wave of testing, were shyness/withdrawal, perceptual sensitivity, and aggression. None of the other tested traits had statistical significant correlation to ToM, but attentional focusing had a positive correlation to the block test and IC, while activity level had a negative correlation to IC. Both shyness/withdrawal and perceptual sensitivity showed a positive correlation with the development of ToM, while…

One of the biggest reasons for revisions of the GDO was to increase the validity and reliability of the test. Original versions based their sampling off of a small group of Caucasian, middle class children (Dalton, 2005; Guddemi et al, 20142; Gesell, 1925) resulting in high criticism. The Gesell Institute made an effort to make the findings of the GDO-R more generalizable. The following information concerning sampling, reliability and validity are based primarily on the findings by the Gesell…

Correlation Vs. Causation Correlation and causation are two very different outcomes of situations. Correlation does not imply causation. A dictionary definition of correlation is that it is a statistical measure that indicates to the extent to which two or more variables fluctuate together. There are two types of correlation, positive and negative. Positive correlation indicates the extent to which those variables increase or decrease in parallel. A negative correlation indicated the extent…

Introduction The article relates to the assessment instrument I will be presenting, Motor-free Visual Perception Test. The purpose of this correlational research study of adult stroke survivors in occupational therapy is to show the relationship between basic visual function and higher-level visual perceptual processing skills. Development After sustaining a brain injury, a person is often left with varying degrees of cognitive and perceptual dysfunction as well as the more obvious motor and…
