Quizplus · Accepted Answer

The goal of forming rational subgroups for an $ \bar{x} $-chart is to select samples that are as homogeneous as possible. Homogeneous samples will have similar variation and will allow for better interpretation of the chart. Heterogeneous samples may result in excessive variation, making it difficult to differentiate between common cause and special cause variation. Therefore, the best choice is option B - homogeneous.
