How do you draw a ID50 graph?

To draw an ID50 graph, first, gather data on the dosage of a substance and the corresponding percentage of subjects exhibiting a specific response (e.g., infection or toxicity). Plot the dosage on the x-axis and the percentage response on the y-axis. Create a smooth curve through the data points, identifying the dose at which 50% of the subjects respond; this is the ID50 value. Label the axes and include a title for clarity.
