Control Group
in an experimental, group of individual who are not exposed to the independent variable that is being tested
-
Critical Thinking
Judgind info before accpeting it
-
Data
Experimental results
-
Duductive Reasoning
Using a general idea to make aconclusion about a specific case
or logic
-
Dependent variable
in an experiment variable that is presumably affected by theindependent variablebeing tested
-
Experiment
A test designed to support or falsigy a prediction
-
Experimental Group
in an experiment, group of individuals who are exposed to an independent variable
-
Hypothesis
Testable explanation of a natural phenomenon
-
Independent variable
Variable that is controlled bh an experimenter in order to explore its relationship to a dependent varialbe
-
Inductive reasoning
drawing a conclution baded on observation
-
Model
Analogous system usded for testing hypothesis
-
prediction
Statement baded on a hypothesis about a conditon that should exist if the hypothesisis correct
-
Science

-
VAriable
in an expereiment a characteristic or event that differs among individuals or over time
-
Probability
the chance that a paricular outcome of an event will occur depends onthe total number of outcomes possible
-
Sampling Error
