Observation
The process of using one or more of your senses to gather information.
Qualitative Observation
An observation that deals with characteristics that cannot be expressed in numbers.
Quantitative Observation
An observation that deals with a number or account.
Inference
The process of making an inference, It an interpretation based on observations and prior knowledge.
Hypothesis
