Observations that deal with a number or amount  are called

• manipulated observations.

• quantitative observations.

Trying to explain a solar eclipse is an example of 

• a prediction.
• an experiment.
• classification.
• scientific inquiry.

One useful tool that may help a scientist interpret data by revealing unexpected patterns is a

• variable.
• graph.
• theory.
• law.

A well-tested explanations for a wide range of observations is called a scientific

• inquiry.
• hypothesis.
• theory.
• law.

Observations that deal with descriptions that cannot be expressed in numbers are called
