Pearson product-moment correlation coefficient

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…

with the conclusions made by the author(s) in the discussion section? Explain your rationale. I believe the authors made an evaluation appropriate to the results of the study. The authors based the implication for school psychologist only on the correlations that were significant, and suggested improvements on practices of school psychologist based on results that were not significant. For instance, the authors suggested that school psychologist address beliefs about ADHD as well as…

of institution, but more so in a correctional setting, studies have concentrated on attitudes of their staff that focus on job stress, job satisfaction, and commitment. Specifically, Paoline and Lambert wanted to determine if there was a direct correlation between the occupational attitudes and key variables of demographics, job and organizational characteristics. For the purpose of this study, I find it imperative to state that this study is one of the first one’s of its kind to measure the…

Edwin Arlington Robinson’s poem, “Richard Cory,” is brimming with irony. The brilliant use of situational irony takes the seemingly perfect life of Richard Cory and surprises us all once we reach the last line of Robinson’s poem. In fact, this poem seems eerily similar to Robin Williams’ situation. Richard Cory and Robin Williams both appeared to have their lives together; both rich, always smiling and making other happy, and were both held to higher standards. However, much like Richard Cory,…

data set, the relationship between line length and Weber’s fraction was almost completely linear and had a slope of zero. At line size two, however, there is a discrepancy (figure two). The result from line size two contradicts Weber’s law since the product of creating that fraction should produce a constant, k, which if plotted should create almost a horizontal…

The purpose of the study, A Psychological Exploration of Engagement in Geek Culture, was to identify and understand why people participate in geek culture. Geek culture is defined as a subculture of enthusiasts that are interested in “obscure” media such as anime, sci-fi, and videogames. However, there are many faucets of the culture and it has become increasingly appealing to mainstream audiences, causing a greater shift in active engagement. Despite geek interests once being marginalized,…

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…

The Pearson correlation of the statistics model may be further corrected small numbers of observed values. The results two-tailed correlation indicates that PAE is not correlated to any of the any of the following indicator of the base-10 concept score, R2, slope. The studies from Siegler and Ramani (2011) the first graders’…

What- For over a century, an ethnographic method known as ‘participant observation’ has been an essential tool utilised in various anthropological and sociological disciplines in order to collect important qualitative research about people, their activities, and their cultures. (Kawulich, B 2005) Participant observation enables a researcher to learn about the studied culture and its associated activities in a natural setting, through the acts of observing and participating in these activities.…

First, the variable Percentage Black Students had a medium negative correlation (r = -0.59) to QDI. A linear regression analysis using Black Student Percentage as the independent variable and QDI the dependent variable resulted in a linear regression equation with a y-intercept of 163.11 and a slope of -0.27, which is statistically…
