According to the textbook there are four forms of conduct manner. The first one is Pearson r it consist of two continuous variables, an example is the SAT or even a grade point average of a college of high school. Spearman rho is two ranked variables, it consist of ranking such as 25 college students have rankings in math and sciences courses. The question would be is there an association between the rankings in math and science. According to Rosnow Point-biserial r is one continuous and one dichotomous such as the gender with the performance of tests scores. Phi Coefficient consists of two dichotomous variables, an example of this would be measuring sound waves but measured in two different parts one high and the other low. Advantages and Disadvantages
The advantages of correlation are that it is used for research to be successfully carried out. When it comes to experiments and surveys. The major advantage is that research is never ending and it can be changed up in so many ways that the variable can come out different. It is important that individuals taking part of the survey is that their answers match their opinion and life. A disadvtange is that the answers to the questions may be bias or even the questions that are asked may be bias. If survey takers are not honest this can be a difficult situation.
