In situations where every/or nearly/case has its own unique rink, and there are no or a few ties, the data are said to be fully ordered" (Monette, Sullivan & DeJong, (2011).The interval data " the most used measured of association for interval data is the correction or Pearson’s r. The correlation coefficient is mathematically related to both phi and Spearman's rho, making comparisons among them possible" (Monette, Sullivan & DeJong, (2011).

"There are several different kinds of relationships between variables. Before drawing a conclusion, you should first understand how one variable changes with the other. This means you need to establish how the variables are related - is the relationship linear or quadratic or inverse or logarithmic or something else" ("Relationship Between Variables ", n.d) advantages and disadvantages for correlational research methods

"Correlation is a measure of association that tests whether a relationship exists between two variables. It indicates both the strength of the association and its direction (direct or inverse). The Pearson product-moment correlation coefficient, written as r, can describe a linear relationship between two variables" Correlation (n.d). As a human service professional and completing research there are advantages and disadvantages to correlational research methods, such as using correlational research it allows us to collect data and determine the strength and direction of what it is we

## Correlation Between Iq And The Grade Point Average Of Students

- 1339 Words

Research shows that there is a correlation that shows the relationshop between the IQ and the grade point average of students. It was found that the correlation is strong at a .75 because it’s a direct relationship. For instance when someone has a higher IQ they are more likely going to have a higher GPA. However although the correlation shows a higher IQ means higher GPA does not mean that is the only reason the GPA is rising, it could be because they hired a tutor, have been studying more or are maybe just in more interesting classes. In correlation studies they show that there is a relationship between two different variables however it is not evidence or proof in any way. The reason it isn’t proof is because it has not been proven that they are directly the reason for the relationship however that they do have common results. Some of the reasons correlation cannot prove anything is because of the limitations; these would be the lack of information about the correlation, sample size or the standard deviation. In our text it states “If the word correlation is broken down co-relation it is expresses what is meant: The characteristics are related and the evidence for the relationship is that they vary together, or co-vary. As the level of one variable changes, the other changes in concert, this happens because both variables contain some of the same information. The higher the correlation the more they may have in common” (Tanner,2011).

Correlation is much easier to prove than causality or causation. Correlation is looking at two different variables and seeing that there is a relationship, but you do not have to recognize and go into depth to find the real relationship between the two. Causality is more difficult to prove than correlation because it involves more factors, and having to rule out of various explanations

Correlation and Cause: Correlation is the relationship between two variables that tend to move in the same direction. Causation is the relationship in which a change in one variable creates a recognizable change in another variable.
