Detailed explanation-1: -Correlation is used to test relationships between quantitative variables or categorical variables. In other words, it’s a measure of how things are related. The study of how variables are correlated is called correlation analysis.
Detailed explanation-2: -The correlation coefficient is measured on a scale that varies from + 1 through 0 to – 1. Complete correlation between two variables is expressed by either + 1 or-1. When one variable increases as the other increases the correlation is positive; when one decreases as the other increases it is negative.
Detailed explanation-3: -A scatterplot is the most useful display technique for comparing two quantitative variables.
Detailed explanation-4: -Correlation is a statistical technique that is used to measure and describe a relationship between two variables.
Detailed explanation-5: -Pearson’s correlation coefficient (r) is used to demonstrate whether two variables are correlated or related to each other.
