EDF 6225 exam 1
science - correct answer Systematic approach for seeking & organizing knowledge about the natural world
purpose of science - correct answer ◦To achieve a thorough understanding of the phenomena under study
ABA seeks to - correct answer discover the real truths (not those held by certain groups, organizations, etc.)
Three different types of investigations provide different levels of understanding - correct answer 1. description
2. prediction
3. control
description - correct answer ◦Collection of facts about observed events that can be quantified, classified,
& examined for possible relations with other known facts
◦Often suggests hypotheses or questions for additional research
prediction - correct answer ◦Relative probability that when one event occurs, another event will or will not occur
◦Based on repeated observation revealing relationships between various events
◦Demonstrates correlation between events
◦No causal relationships can be interpreted
◦Enables preparation
control - correct answer ◦Highest level of scientific understanding
◦Functional relations can be derived
Specific change in one event (dependent variable).... Can reliably be produced by specific manipulations of another event (independent variable)...
And the change in the dependent variable was unlikely to be the result of other extraneous factors (confounding variables)
◦Events can only really be "co-related"
Nearly impossible to factor out all other possible "causes"
attitudes of science - correct answer - Definition of science lies within the behavior of scientists, not the instruments or materials they use
- Only known as science due to an overriding idea of "scientific method"

6 attitudes of science - correct answer 1. DETERMINISM
2. EMPIRICISM
3. EXPERIMENTATION
4. REPLICATION
5. PARSIMONY
6. PHILOSOPHIC DOUBT
determinism - correct answer - Assumption upon which science is predicted
- Presumption that the universe is a lawful and orderly place in which all phenomena occur as the result of other events
- Events do not just occur at will
- Events are related in systematic ways
empiricism - correct answer - Practice of objective observation of phenomena of interest
- What all scientific knowledge is built upon
- "Objective" is the key to gaining a better understanding of what is being studied
experimentation - correct answer - Basic strategy in most sciences
- Experiment:
