Question

in a scientific experiment, the responding variable can also be called the.
○ operational variable
○ manipulated variable
○ dependent variable
○ independent variable

Explanation:

In a scientific experiment, the responding variable is the one that changes in response to the manipulated (independent) variable. The dependent variable is defined as the variable that depends on the independent variable and is the one being measured or observed (responding). The operational variable refers to how a variable is defined and measured. The manipulated variable is the independent variable (the one changed by the experimenter). The independent variable is manipulated, not the responding one. So the responding variable is the dependent variable.

Answer:

C. dependent variable
