.The relationship between stressor and response can
be described qualitatively:
- A response can be described as high, medium, or low.
- A response can be described as "yes" or "no."
For example: one researcher assumed that seeds would
not germinate if they were inundated with water at the critical
time. This stressor-response relationship was described simply as
a yes or no. Qualitative analysis is useful when data are scant
and an answer is needed in a hurry.
However, quantitative analyses are strongly preferred
over qualitative analyses. We'll discuss these on the next screen.
If quantitative analysis is not needed, move on to Assessing
Multiple Stressors.
We'll talk more about how these determinations are
used in the next module, Risk Characterization.
