Question

what term represents the part of an experiment that doesnt change from one trial to the next?
constant
independent variable
dependent variable
hypothesis

Explanation:

To solve this, we analyze each option:

• A constant is a factor that remains unchanged throughout an experiment's trials.
• An independent variable is manipulated (changes) to observe its effect.
• A dependent variable changes in response to the independent variable.
• A hypothesis is a proposed explanation, not a non - changing part of trials.

So the term for the part that doesn't change is "constant".

Answer:

A. constant
