in an experiment the ____ is manipulated by the researcher its effects on the ____ are measured.
d) dependent variable/ confounding variable
b) independent variable/ dependent variable
a) dependent variable/ independent variable
c) confounding variable/ independent variable

Explanation:

In experimental design, the independent variable is the one the researcher manipulates (changes) to observe its impact. The dependent variable is what is measured to see the effect of the independent variable. Option D swaps them and includes a confounding variable (unwanted variable), Option A also swaps, and Option C involves a confounding variable incorrectly. So the correct pair is independent variable (manipulated) and dependent variable (measured).

Answer:

B) independent variable/ dependent variable
