WebbA partial interaction allows you to apply contrasts to one of the effects in an interaction term. For example, we can draw the interaction of collcat by mealcat like this below. Say that we wanted to compare, in the context of this interaction, group 1 for collcat vs. groups 2 and 3. The table of this partial interaction would look like this.

This p-value is greater than 5% (α), therefore we fail to reject the null hypothesis. There is no evidence of a significant interaction between variety and density. So it is appropriate to carry out further tests concerning the presence of the main effects. inspiration rpWebbInteraction means that the association between an independent variable and the dependent actually depends on the value of another independent variable. In general case, a regression model like: y = β 0 + β 1 x 1 + β 2 x 2. indicates that for one unit increase in x 1, mean y differs by β 1 unit, regardless what value x 2 is. inspiration rooms living
