# Correlation In Psychology

796 Words 4 Pages
How do we learn what we know? A variety of approaches are used by researches to gain knowledge about habits and psychological processes. One of the five approaches used by 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 correlation, there are two or more variables. These variables can have a positive, negative
Scatterplots are graphs with a horizontal and vertical axis used in mathematics to plot variables on. Scatterplots display positive, negative and zero correlations. When a graph is increasing upwards, the correlation is positive, and when it trends downwards the correlation is negative. If data points are scrambled all over the scatterplot, the correlation is nonexistent. There are many benefits to correlating. If a perfect negative or positive correlation is present, researches are enabled to predict events that could occur in the future. Furthermore, a well thought out hypothesis based on the relationship can produce new discoveries. For example, students with high attendance rates, receive higher grades. Researches can predict that students with multiple absences receive lower grades. Correlation also informs groups of people at high risk for physical or behavioral problems. For instance, humans overweight have a higher risk of heart attacks. Knowing this relationship, heavy weighted humans should take better care of their bodies and lose weight to reduce their risk of a heart attack. Lastly, the method of correlation increases our understanding of positive and negative events that are relatable. There are limitations of correlating set by causations. Correlations, including perfect ones, do not cause events to occur. For example, an increase in salary correlates with a higher position. A salary increase does not dictate a higher position at work. These variables are related because typically higher position earns more money. Two or more variables, associated with each other, examined carefully enable anybody looking at the data on a scatterplot to make bold predictions on the events

• ## UCL Jurisprudence: The Conventional Economic Approach To Law

Economics is concerned with maximising utility, not wealth. Transactions are only economically efficient if they move goods into the hands of those who gain the most utility from them, thereby increasing the total utility of society. But how are we to measure the utility which an individual gains from a good when this is so subjective? At this point economics assumes the following: the greater the monetary value he places on a good, the more utility he gains (or expects to gain) from it. There are of course problems with the rich paying more for a good because they can, and not because they will gain any more utility than someone poor, and this is why the assumption is not very good.…

• ## Conscientiousness And Academic Performance

This shows the relationship between conscientiousness and academic performance. This also includes both p and r values for this data set. The below shows that there is a level of correlation between the two factors: conscientiousness and final grades. The r values shows that the two variables tend to increase together. Although it is not an overly strong correlation the p value of 0.03 shows that the data set is statistically significant.…

• ## Case Study Of Pull Together The Data

The continuous analysis allows companies to alter and understand their performance measure in a better way. For example company can relate the increase in financial performance with low truancy but still the reason of failure to appear will remain unknown. According to the analysis of the relationship between company efforts and outcomes, managements were able to refine their existing process. This suggests that even though companies’ profit is increasing because of low truancy but, only because of non-financial technique the company is able to determine as to why the employees do not want to come to work which supports in forming a better work-place. A healthy environment is very much necessary for delivering the best work, which in turn will lead to increase in profit and generate revenue without financial investment.…

• ## Regression Analysis In Statistics

To the degree that it is based on counting various pairs in a relationship. Known as a statistical tool that investigates relationships among variables, regression analysis seeks to determine the unintended effect of one variable to another. This is typically a relationship between the dependent variable and one or more independent variables.…

1.576 2 102 .212 The significance level from the Levene’s test yield that the variability in the two conditions is not significantly different, as the significance level is greater than .05. 3. Overall, the assumptions have been met. The descriptive data interpretation of a negative, skewness and positive kurtosis yields that the variance is skewed, and the p-value of .001 yields that the data is from a normal distribution. Research Question, Hypotheses, and Alpha Level 1.…

• ## Rich Manufacturing Case Study: Rich Manufacturing

When cost-plus pricing is used, it is very easy to determine what makes up a particular cost that a company is paying for a product. Picaretto should not contest the price increase because the price increase can easily be justified due to an increase in Bhagat’s labor which is identified in their labor contract (Meehan, n.d.). The price increase that Bhagat is implementing will more likely be justified in the long run rather than the short run. The initial price increase will cause some concern for Rich Manufacturing, along with any other company purchasing the product from Bhagat because they will need to adjust for the price increase accordingly to maintain their profit margins. However, over time, the price will again remain constant and will be more justified.…

• ## Substitution Between Monitoring And Monitoring System

However, when the IT-enabled monitoring tool is available, the employers can verify the contractors’ actual effort and only continue the employment if they find that the contractors’ levels of effort are acceptable. Therefore, by using an efficient monitoring system, the employers don’t need to emphasize the contractors’ reputation too much because of their capability to ensure the awarded contractors’ actual effort [16]. Second, monitoring provides better information about the contractors’ performance and how to improve it, so that it can help to save time and decrease the cost uncertainty. Before the IT-enabled monitoring tool is introduced, the employers might prefer for contractors with a high reputation not only because of their higher expected effort but also because of the smaller cost uncertainty (variance) [8]. However, with the help of the IT-enabled monitoring system, employers can have better information about contractors’ performance and instruct them to perform more efficiently.…

• ## Reflection Essay: Was My Life Worthwhile?

I don’t need to be so rich that I can’t possibly spend all the money because happiness from money doesn’t increase much more after a certain point. This is also supported by Vaillant. His study’s, “…findings echoed those of other studies -- that acquiring more money and power doesn 't correlate to greater happiness” (Gregoire). Another study on wealth had a related finding when you were in the right economic spot for you. The study was about the impact of assets and life satisfaction, and they found that assets affect how older people view their life satisfaction.…
