What type of data is analyzed using the Spearman's Rho test?

  1. Nominal

  2. Continuous

  3. Ordinal and continuous

  4. Categorical

The correct answer is: Ordinal and continuous

The Spearman's Rho test is utilized for analyzing the relationship between two sets of data that are ranked, making it particularly suitable for ordinal data. Ordinal data includes ranks where the order matters, such as rankings of preferences or satisfaction levels. This test can also handle continuous data that has been converted to ranks, allowing for a flexible application in various research scenarios. By assessing how well the relationship between two variables can be described using a monotonic function, Spearman's Rho provides insights into the strength and direction of a relationship. Continuous data that does not meet the assumptions required for parametric tests could also be analyzed using Spearman’s Rho, thus enabling researchers to draw valuable conclusions in cases where traditional methods may not be appropriate.
