Four requirements for science to result in knowledge acquisition?
Rational
- Inference based on logical reasoning
Skeptical
- Seek to scrutinize patters
Objective
- Unbiased by preconceived notions
Methodologically Materialistic
- Explanations are natural and not supernatural
What are the components of a scientific argument and why is it important?
Claim
- Proposed explanation
Evidence
- Proof to further strengthen the claim
Reasoning
- Connects evidence to claim intellectually
Inferential Strength
- Quality of the argument and how it connect the evidence to the claim
Its important,
- Ensures our understanding is based on scientific evidence
Explain a, hypothesis, prediction, fact and theory
Hypothesis
- A proposed testable explanation for an observation or phenomenon
Prediction
- Testable statement about the expected outcome of an experiment or observation
Fact
- Something that has been tested and proven many times
Theory
- A hypothesis supported by a vast amount of evidence
Inductive vs. Deductive Reasoning
Inductive
- An assumption based on particular or broad evidence (eg. 1 black swan means all must be black)
Deductive
- An assumption going from broad to general, (eg. robins can fly, all birds can fly, therefore robins are birds)
Why does science proceed via rejecting?
It is more reliable and rigorous way to build knowledge than trying to confirm them.
Descriptive vs. Hypothesis Testing
Descriptive
- An assertion of pattern in the physical and or natural world
Hypothesis Testing
- An assertion related to the validity of a scientific hypothesis (causal explanation for a pattern/observation)
What is extrapolation?
Replicating an environment or situation within a smaller model.
Observational vs. Manipulative Studies
Observational
- Natural habitat without manipulating variables
Manipulative Studies
- Manipulating a variable within an experiment to see the effect
What is a confounding variable?
Another unconsidered cause for a result being studied
