Test Rho Spearman. Spearmans Rho is a non-parametric test used to measure the strength of association between two variables where the value r 1 means a perfect positive correlation and the value r -1 means a perfect negataive correlation. You have a correlational design.
The Spearman rank correlation test does not carry any assumptions about the distribution of the data and is the appropriate correlation analysis when the variables are measured on a scale that is at least ordinal. If the calculated Spearmans rho is greater than the critical value from the table then reject the null hypothesis that there is no correlation. I found a strong positive correlation between customer age and household income the older the customer the higher the household income.
For example first second and third in a race are ordinal data.
