This measure indicates both the degree and direction of the relationship between variables. However, it yields no information concerning the cause of the relationship. Correlation techniques are available for both parametric and nonparametric data.

However, it yields no information concerning the cause of the relationship. Correlation techniques are available for both parametric and nonparametric data. The Pearson Product Moment Correlation is also used in other inferential statistical techniques such as regression analysis and factor analysis to help researchers and theorists build models that reflect the complex relationships observed in the real world.
Jones, so he must not be angry that my report was not submitted on time. This is the degree to which two events or variables are consistently related. Correlation may be positive i. However, correlation does not give one any information about what caused the relationship between the two variables.
Properly used, knowing the correlation between variables can give one useful information about behavior. For example, if I know that my cat gets sick when I feed her "Happy Kitty" brand cat food, I am unlikely to feed her "Happy Kitty" in the future. Of course, knowing that she gets sick after eating "Happy Kitty" does not explain why she gets sick.
It may be that she is sensitive to one of the ingredients in "Happy Kitty" or it may be that "Happy Kitty" inadvertently released a batch of tainted food. The neighborhood stray may eat all her Correlation research papers Kitty" food, causing her to have eaten something else that causes her to get sick, or I changed her food to "Happy Kitty" at the same time she was sick from an unrelated cause.
All I know is that when I feed her "Happy Kitty" she gets sick. Although I do not know why, this is still useful information to know.
The same is true for the larger problems of sociology. There are a number of ways to statistically determine the correlation between two variables. The most common of these is the technique referred to as the Pearson Product Moment Coefficient of Correlation, or Pearson r.
This statistical technique allows researchers to determine whether the two variables are positively correlated i. Causation However, as mentioned above, knowing that two variables are correlated does not tell us whether one variable caused another or if both observations were caused by some other, unknown, third factor.
As opposed to the various techniques of inferential statistics where we attempt to make inferences such as drawing conclusions about a population from a sample and in decision making by looking at the influence of an independent variable on a dependent variable, correlation does not imply causation.
This does not mean that the alarm clock caused the grandfather clock to chime or that the grandfather clock caused the alarm clock to go off. In fact, both of these events were caused by the same event: Although it is easy to see in this simple example that a third factor must have caused both clocks to go off, the causative factor for two related variables is not always so easy to spot.
To act on such unfounded assumptions about causation as inferred from correlation is part of the cycle of superstitious behavior.
Many ancient peoples, for example, included some sort of sun god in their pantheon of deities. They noticed that when they made offerings to their sun god, the sun arose the next morning, bringing with it heat and light.
So, they made offerings. From our modern perspective, however, we now know that the faithful practice of making offerings to a sun god was not the cause of the sun coming up the next morning. Rather, the apparent phenomenon of the rising sun is caused by the daily rotation of the earth on its access.
The classic example of showing the absurdity of inferring causation from correlation was published in the mid 20th century in a paper reporting the results of an analysis of fictional data. Neyman used an illustration of the correlation between the number of storks and the number of human births in various European countries.Pearson's correlation coefficient has a value between -1 (perfect negative correlation) and 1 (perfect positive correlation).
If no underlying straight line can be perceived, there is no point going on to the next calculation. Wk: 4 Correlation Response Paper Stacy Harris BSHS/ 0ctober 31, University of Phoenix Staci Lowe Correlation Describe at least two different methods of establishing correlation between variables and provide an example of each.
According to the text, “There are four forms of Karl's Pearson's product-moment r.
In a correlation study using the spreadsheet program Excel and its data analysis feature, a Pearson coefficient value of r was calculated. This indicates a high positive relationship between the two variables, time and accuracy.

RESEARCH PAPER ON CORRELATION MaxQDPro Team Anjan.K Harish.R II Sem skybox2008.com CSE 06/10/09 Research Paper On Corelation 2. Correlation studies attempt to show a relationship between two or more variables.
For example, there are many questions that one can ask in the social AND health sciences that touch upon the possibility of a relationship existing between two variables and the nature of that relationship if it exists.
