How Does Drug Treatment Affect Cell Viability?
- Scientific question
- Does cell viability change as the concentration of Drug A increases, compared with vehicle-treated cells?
- Experimental groups
- Vehicle, Drug A 0.5 µM, Drug A 2 µM and Drug A 8 µM, with viability expressed as a percentage of control.
- Selected analysis
- Welch’s one-way ANOVA across the four groups, followed by Games–Howell post-hoc pairwise comparisons.
- Role of the chart
- Every data point stays visible beside each group’s summary and error bars, with the comparisons against vehicle annotated on the figure.
This example uses simulated data created for demonstration. It illustrates the analysis workflow and is not an experimental result.
