A hypothesis that has been supported by a significant amount of data
The principles of right and wrong that guide an individual in making decisions.
use of science to fit a practical purpose
data that is measurable and can be expressed in numbers; examples include 14cm and 96% correct answers
data that cannot be measured in numerical values; behaviors, emotions, scents, textures, etc.
