Correlation analysis helps to determine the association between two or more variables. The association can either be positive or negative. Positive correlation means the variables are moving towards the same direction while negative correlations means that the variables are moving towards the opposite direction. Correlations can also be strong (greater than 0.5) or weak (less than 0.5). Tobit Research Consulting Limited will help you to know how to calculate and interpret the correlation coefficient for your study.
