Identify the dependent variable in the following hypothesis statement: The concentration of pesticide in pond water (g/L) has an effect on the growth rate (g/day) of Oregon spotted frog, Rana pretiosa. Select one: a. Pond water b. Oregon spotted frog c. Pesticide concentration d. Growth rate

Identify the dependent variable in the following hypothesis statement:
The concentration of pesticide in pond water (g/L) has an effect on the growth rate (g/day) of Oregon spotted frog, Rana pretiosa.
Select one:
a. Pond water
b. Oregon spotted frog
c. Pesticide concentration
d. Growth rate

Answer

• d. Growth rate
  Explanation:
  The dependent variable is what is measured in an experiment and what is expected as the results. It depends on the independent variable and is not manipulated as with the case of independent variable. In the above case, the dependent variable is the growth rate, because it is the result of pesticide concentration. On the other hand, pesticide concentration is independent concentration.
