Question

1. what is the dependent variable in an experiment?

the outcome that is measured or observed
the control group
the experimental theory
what the scientist changes

Explanation:

To determine the dependent variable in an experiment, we analyze each option:

• "The outcome that is measured or observed" matches the definition of a dependent variable, as it depends on the independent variable and is what we measure.
• "The control group" is a group used for comparison, not a variable.
• "The experimental theory" is the hypothesis or idea being tested, not a variable.
• "What the scientist changes" is the independent variable, not dependent.

Answer:

A. The outcome that is measured or observed
