To determine whether the relationship between the independent and dependent variables systematically varies as a function of the moderator, a test for interaction is needed. This involves conducting a statistical analysis such as a regression model, and specifically testing whether the interaction term (which captures the relationship between the independent variable and the moderator) is significant. Graphs and visualizations can also be helpful in understanding the nature of the interaction, but a test is needed to determine its significance. A probe for an interaction is not a commonly used term in statistical analysis. Visualization of the XY relationship is not sufficient to test for an interaction involving a moderator.
