Systematic approach for seeking and organizing knowledge about the natural
world
Ans: Science
To achieve a thorough understanding of the phenomena under study and seeks to
discover the real truths. No bias by groups or organizations or by the scientists
themselves.
Ans: What is the purpose of the systematic approach for science?
Describe the three levels of understanding for science
Ans: Description, prediction, and control
What is the highest level of understanding for science?
Ans: Control
What is the lowest understanding for science?
Ans: Description
Collection of facts about observed events that can be quantified, classified, and
examined for possible relations with other known facts.
Ans: Description
Can suggest hypothesis, questions, or additional research ideas

Relative probability that when one events occurs, another event either will or will
not occur. Demonstrates correlation between events.
Ans: Prediction
Must be based on repeated observations
Ans: Prediction
Causal relationships can not be determined. Correlation does not mean
causation.
Ans: Prediction
Functional relations can be derived. Specific change in one event can reliably be
produced by specific manipulation of another event and the change in the
dependent variable was unlikely to be the result of other extraneous factors
(confounding variables).
Ans: Control
The universe is a lawful and orderly place which all phenomena occur as the
result of other events. Events do not occur at will. Events are related in
systematic ways.
Ans: Determinism
The practice of objective aberration of the phenomena of interest
Ans: Empiricism
All scientific knowledge is built upon

Ans: Empiricism
Controlled comparison of some measure of phenomena of interest (dependent
variable) under two or more different conditions in which only one factor at a
time (independent variable) differs from one condition to another.
Ans: Experiment
The repeating of an experiment. How scientists determine the reliability and
usefulness of their experiments. Can be within an experiment or across
experiments.
Ans: Replication
All simple explanations are ruled out before more complex or abstract
explanations are considered.
Ans: Parsimony
The continuous questioning of the truthfulness and validity of all scientific theory
and knowledge
Ans: Philosophic doubt
A systematic approach to the understanding of natural phenomena as evidenced
by description, prediction, and control that relies on determinism as its
fundamental assumption, empiricism as its prime directive, experimentation as its
basic strategy, replication as its necessary requirement for believability, parsimony
as its conservative value, and philosophic doubt as its guiding conscience.
Ans: Definition of science
Does basic research
