Characteristics of Correlation Analysis
It is a statistical method for evaluating the relationship strength between two variables The underlying presumption for this research is that the quantitative variables have a linear relationship. Using the statistical information that is already available, correlation analyses determine the kind and degree of correlation (amount of similarity) of two quantitative variables. It never explains how they are connected. Below, we have mentioned some of the characteristics of Correlation Analysis.
- The statistical relationship is measured using the "correlation coefficient," which shows the strength and direction of the association. It ranges between -1 to +1.
- A low correlation shows little relationship between the variables, whereas a high correlation shows a considerable association between two or more variables.
- A correlation coefficient of +1 shows that two variables are related perfectly in a positive manner; a correlation coefficient of -1 shows that two variables are related perfectly in a negative manner; and a correlation coefficient of 0 shows that there is no linear relationship among the two variables under study.
- Correlation coefficients do not indicate whether one variable moves in response to another. It makes no effort to distinguish between independent and dependent variables.
- Rank Spearman's Correlation Coefficient and Pearson's Product Moment Correlation Coefficient are the two correlation coefficients that are typically used in applications.
- Examples have the relationship between a student's IQ and their grades or the link between the volume of their academic work and success.
- Studies on correlation are done to help predict future events or to help explain important human behaviours.
The major characteristic of correlation analysis is to seek out? (A) Differences among variables (B) Variation among variables (C) Association among variables (D) Regression among variables
Searching for associations between variables is the main characteristic of correlation analysis. Any scientific study's main goal is to determine the relationship between two or more factors in order to get a rational, more realistic conclusion. Correlation analysis is frequently used in research to examine the strength of the relationship between variables.
