SPSS Help Tells About Correlation Tests
There are two types of analysis in statistics that test on relationship between data. One of them is dependence which refers to any statistical relationship between two or more random variables in two or more sets of data. At the same time, correlation is a term that refers to any of a broad class of statistical relationships involving dependence. In other words, correlation is general meaning of dependence. Examples of dependence include correlation between physical statures of parents and offspring as well as correlation between price and demand in marketing. Correlation analysis is very useful, because it shows relationship that can be exploited on practice.
There are a few different types of correlations like Bivariate, Pearson correlation,Kendall’s Tau, Spearman’s rank, simple scatter plot, partial correlation, etc and each one is being used for different purposes. For example, Pearson correlation is sensitive only to a linear relationship between two variables. So, if you are in the midst of research and you need to assess some data for correlation, you will need to use correlation tests to do that. But what tests do you use and why? Most students and researchers don’t possess skills to give satisfactory answer to this question, so they look for professional statisticians to deal with their data.
