Empirical knowledge.
The scientific method is the system of advancing knowledge by creating a question, collecting data by observation and experimentation, and testing a hypothesis.
Qualitative observation is subjective. Quantitative observation is the result of controlled testing procedures with prescribed procedures in place. Quantitative testing is sometimes called empirical testing.
Empirical knowledge come from observation only. You don't know why or have any idea of why reaction A follows situation B but you have seen it happen so many times that you KNOW that is what is going to happen. People knew that things fell down long before there was a theory of gravitation. Such knowledge was empirical. Empirical knowledge not only comes from observation but also by testing.

Testing and observation
From Wiki: consisting in (of) systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses
knowledge doesn't help you, well it does in a way because knowledge is things you know like when things say "testing your general knowledge" it means testing what you know! Hope this helps
the purpose of testing
Meausring them!
Hypothesis
Not book knowledge. Knowledge acquired by experimenting or testing by yourself.
There is no "Theory of Science" however the basis of science is: * Observation produces information * Observation leads to conclusions * Conclusions lead to the generation of theorys * Testing confirms or denies theories * The las step leads to better theories to test * In the end we will have a pretty good idea of how things work.
