The following diagram was developed from a designed experiment.

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.
