Lesson 3-Dose-Response Relationships

Water-Soluble Plant Fertilizer

The x-axis indicates the dose as a percent concentration on a scale from 0 to 100. The y-axis indicates the response on a scale from 0 to 10. The response for this experiment is the number of seeds that did not germinate out of a sample of 10 seeds.

When the data testing the effect of fertilizer on seed germination is plotted, the results are as follows. At a dose of 0%, 1 seed did not germinate; at 6.25%, 9 seeds did not germinate; at 12.5%, 10 seeds did not germinate; at 25%, 10 seeds did not germinate; at 50% 10 seeds did not germinate; at 100%, 10 seeds did not germinate.
