Examples
- The phi coefficient is a method used to determine the strength and direction of association between two nominal variables in a population.
- Researchers used the phi coefficient to analyze the correlation between the two binary variables and determine the strength of the relationship.
- The phi coefficient value ranges from -1 to 1, making it easy to interpret and compare different correlations.
- To calculate the phi coefficient, a two-by-two contingency table is created, and the values are calculated based on the observed frequencies.
- Using the phi coefficient, researchers were able to determine a positive correlation between the variables being studied, indicating a strong relationship between the two sets of binary data.
