Quantitative Observation
Using numbers or measurements to describe something.
Inference
An explanation of an observation based on prior knowledge

Dependent/Responding Variable

Scientific Method
The way scientist study and learn about the world
C-E-R

Claim
Is the answer to the question you are trying to answer
Evidence

Reasoning
The how or why the evidence supports our claim; scientific rule.
