independent variable
inverse relationship
percent error
direct relationship
dependent variable
a mathematical way of showing
when one variable increases and the
other variable decreases
when two variables both increase or
decrease together
what is measured and affected during
an experiment
what is changed by the researcher
during an experiment

Explanation:

• Independent variable: In an experiment, it is what is changed by the researcher.
• Inverse relationship: When one variable increases and the other variable decreases.
• Percent error: A mathematical way of showing accuracy (though the provided options seem a bit off - percent error is actually \(\frac{\vert\text{experimental value}-\text{theoretical value}\vert}{\text{theoretical value}}\times100\%\), but among the given options, it's the closest to a "mathematical way of showing" something related to error).
• Direct relationship: When two variables both increase or decrease together.
• Dependent variable: What is measured and affected during an experiment.

Answer:

• Independent variable: what is changed by the researcher during an experiment
• Inverse relationship: When one variable increases and the other variable decreases
• Percent error: a mathematical way of showing (accuracy - though not a perfect match, but among the given options)
• Direct relationship: when two variables both increase or decrease together
• Dependent variable: what is measured and affected during an experiment
