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 correlation, there are two or more variables. These variables can have a…

It also predicts that the use of humor as a coping strategy is negatively correlated with self-defeating humor Meaning, for example, if an individual has a lower 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…

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…

positive correlation between the years of high school completed and the income of the respondent. The more years of high school that were completed led to a higher income for the respondent. This was calculated by a Pearson product-moment correlation coefficient. The values that were found were positive with r=0.208, n=906, p=0.000. This is summarized by the scatterplot above. The Sig value strengthens the argument for a positive correlation between years and school and a higher income level, as…

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…

Method Participants We collected data from a sample of undergraduate students at the University of Colorado at Boulder. The students were all in an upper division course titled Research Methods in Psychology. The participants were between the ages of 18 to 32, with a mean age of 20.99 years and a standard deviation of 1.82 years. Out of the 208 students that we collected data from, 80 were male and 128 were female. In terms of class year, one was a freshman, four were sophomores, 98 were…

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…

Purpose and Hypotheses of the Study The study by Mercedes Stanley and Deborah Pollard (2013) had three purposes. One was to examine the pediatric nurse’s ability and level knowledge to assess the management of pediatric pain. The second purpose of this study was to examine how a nurse’s prior experience would affect the attitude and ability to competently administer pediatric pain management to patients. A third purpose was to observe the level of self-efficacy among a group of North…
