BIOLOGY 101 EXAM 1 STUDY GUIDE
Science
An intellectual activity, encompassing observation, description, experimentation, and
explanation of a phenomena naturally occurring
Empirical Knowledge
Thinking that relies on testable, rational and repeatable observation and experimentation.
Scientific Method
1. Do background research
2. Make observations
3. Form a hypothesis
4. Devise a testable prediction
5. Conduct critical experiment/collect data
6. Draw conclusions/analyze results
7. Revise hypothesis if needed
Hypothesis
A proposed explanation or supposition for a phenomenon based on limited evidence as starting
point to be further investigated
Theory
A hypothesis that is exceptionally well-supported by the data and endured the experimental time
When new data is found, theories can be revised
Experimental Design
1. Sample size
2. Treatment/ Experimental group
, lOMoARcPSD|118 976 98
3. Control group
4. Variable (Independent and Dependent)
5. Blind or double blind strategies
6. Randomization
7. Repeatable
Treatment
Any experimental condition applied to individuals
Experimental Group
A group of individuals who are exposed to a particular treatment
Control Group
A group of individuals who are treated identically to the experimental group with the one
exception: they are not exposed to the treatment
Dependent Variable
Characteristics of you experimental system that are subject to change. What you are
measuring/the data you collect
Independent Variable
Variable that doesn’t depend on another variable.
Blind Strategy
The experimental subjects do not know what treatment being received
Double Blind Strategy
Neither the experimental subjects nor the experimenter knows what treatment the subject is
receiving
Randomized
The subjects are randomly assigned into the experimental and control group
