1.2 The Scientific Method Flashcards
Induction (Inductive reasoning)
Involves using a small set of specific observations as the basis for forming a general statement about a larger set of observations
Variables
Characteristics or conditions that change or have different values for different individuals.
Example: personality, intelligence, age, gender, self-esteem, height, weight, and so on.
Hypothesis
A statement that describes or explains a relationship between or among variables. A hypothesis is not a final answer but a proposal to be tested and evaluated.
Deduction (Deductive Reasoning)
A general statement as the basis for reaching a conclusion about specific examples
Scientific Method
A method of acquiring knowledge that uses observations to develop a hypothesis, and then uses the hypothesis to make logical predictions that can be empirically tested by making additional, systematic observations.
Typically, the new observations lead to a new hypothesis
Science Is Empirical
Answers are obtained by making structured or systematic observations
-Results will provide clear support for the hypothesis or will clearly refute the hypothesis
Science Is Public
Replication
Observations are available for evaluation by others
Repetition of observation allows verification of the findings. Only public observations can be repeated, and only public observations are verifiable
Science Is Objective
outcome is not skewed by bias
This never-ending process of using empirical tests (observations) to build and refine our current knowledge (hypothesis) is the basis of the scientific method.
The scientific method can be viewed as a circular process or a spiral of steps. Initial observations lead to a hypothesis and a prediction, which leads to more observations and then to a new hypothesis.
What is pseudoscience? (Science vs Pseudoscience)
A system of ideas often presented as science
Lacks some of the key components essential to scientific research
Examples: aromatherapy, astrology, and intelligent design.
Unsupported by empirical evidence
