The diagram shown is typical of an interaction plot used in the analysis of designed experiments.
* Confounded:
* Confounding occurs when the effects of two factors cannot be separated. The diagram does not indicate this.
* Replicated:
* Replication refers to repeating the experiment or conditions multiple times to ensure reliability, not depicted here.
* Show Randomization:
* Randomization refers to the random assignment of treatments to experimental units. The plot does not indicate this.
* Show Interaction:
* Interaction occurs when the effect of one factor depends on the level of another factor.
* The crossing lines in the plot indicate that the response to Factor A changes depending on the level of Factor B, demonstrating an interaction between the two factors.
