Example #2: A researcher is studying the conditions under which commercially raised shrimp reach maximum weight gain. Two water temperatures (25 degrees, 35 degrees) and four water salinity levels
(10%, 20%, 30%, 40%) are selected for study. Shrimp are raised in containers with specified water
temperatures and salinity levels. The weight gain of the shrimp in each container is recorded after a six-week study period.
a) Identify the response variable.
b) Identify the explanatory variable(s) in this experiment
