Measuring Relationships (Association and Correlation)
An important step in determining the appropriate statistical test procedure is to know the type of variable we are observing. What is the independent variable and the dependent variable? After the variable is determined, then determine how to measure the variable (variable measurement scale)? If we already know/determine this, it will be easy for you to determine the appropriate statistical test procedure.
What is the Variable Measurement Scale?
- Test Statistics: → Chi-Square / Phi . correlation
- Statistical Test: → Spearman or Kendall Correlation
- Note: → Pearson correlation cannot be implemented because the variables are not normally distributed
- Both Normal?
- Statistical Test: → Pearson Correlation
- Statistical measurement: → r
- Other
- Statistical Test: → Spearman or Kendall Correlation
- Note: → Pearson correlation cannot be implemented because the variables are not normally distributed
- Test Statistics: → None match
- Test Statistics: → None match
- Statistical Test: → Spearman or Kendall Correlation
- Note: → Pearson correlation cannot be implemented because the variables are not normally distributed
