From a statistical point of view, the mathematical expression of such relationships is called correlation. 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. However, my cat's digestive problems might not have anything to do with "Happy Kitty" at all.

The neighborhood stray may eat all her "Happy 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. 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.

For example, if I have two clocks that keep perfect time in my house, I may observe that the alarm clock in my bedroom goes off every morning at seven o'clock just as the grandfather clock in the hallway chimes. Effects of disease severity and fear of negative evaluation. Health Psychology, 17 , This study used questionnaire packets to assess the relationship between disease severity psoriasis and the fear of negative evaluation that psoriasis patients experience.

A number of other variables considered relevant to this relationship were also measured with additional scales interpersonal discomfort, quality of life, reactions to symptoms, perceived stigmatization and others. Pearson correlations were also computed for relationships between many of the additional scales and the SAPASI scales using multiple regression analyses.

Loneliness and nursing home admission among rural older adults. This study examined the relationship between older adults' feelings of loneliness and their subsequent admission to nursing homes. Measures normally associated with admission to a nursing home such as age and level of functioning were controlled. Admission status admitted or not admitted to a nursing home at a four-year follow-up were correlated with loneliness scores.

Still participating after all these years: A study of life task participation in later life. This study investigated the relationship between variables such as social life and organizational affiliation to life satisfaction in older Americans. They found that social life was critically important in predicting life satisfaction, especially in those older Americans who were not working. These finding held up even when factors such as health, self-reported vitality, social support, and congeniality were controlled.

A correlation coefficient was used to measure the degree of relationship between subjects' FNE scores and their SAPASI scores. Pearson correlations were also computed for relationships between many of the additional scales and the SAPASI scales using multiple regression analyses.

Negative correlation: Negative correlation is when an increase in one variable leads to a decrease in another and vice versa. For example, the level of education might correlate negatively with crime. Correlation research method is used in scientific research to study the association and/or relationship between variables. When the association between two variables becomes correlation coefficient, it is being calculated through quantitative measure.
