Depandent variable
Evidence; information gathered from observation
data
A logical interpretation based on prior knowledge and experience
inference
Well-tested explanation that unifies a broad range of observations and hypotheses, enabling scientists to make accurate predictions about new situations
theory
Define bias
Particular preference or point of view that is personal rather than scientific
Group in an experiment that is exposed to the same conditions as the experimental group except for one independent variable
control group
The act of noticing and describing events or processes in a careful orderly way.
observation
What is the definition of science?
The use of evidence to construct testable explanations
What does science propose explanations based on?
Based on evidence and understanding
What is a hypothesis?
Testable explanation that can be tested
What happens after a hypothesis is formed?
A controlled experiment
descriptions, characteristics that cannot be measured
qualitive data
Define quantitative data
numbers, characteristics, that can be measured
What happens if an experiment proves a hypothesis?
experiments is repeated be gather more supporting data
