HOW SCIENCE IS DONE Flashcards
a system of acquiring knowledge
through observation and the
experimental testing of
hypotheses
Scientific Method
based on
obtaining and analyzing empirical
evidence to support the reasoning
process
Scientific Method
Employing your five senses to
perceive objects or events
Asking questions: one or more
questions are generated
Observation
A statement is testable if evidence can be
collected that either does or doesn’t
support it
It can never be proven beyond doubt
Often must be refined and revised or
discarded
Is a statement made in advance that
states the results that will be
obtained from testing the hypothesis
Often written in the form of an “if-then” statement
Forming a Hypothesis
Testing a hypothesis or prediction by
gathering data under controlled conditions
– conducting a controlled experiment
Based on a comparison of a control
group with an experimental group
Experimenting
the condition being
tested in the experiment otherwise
known as the independent variable
Treatment
is a group in an
experiment that do not receive the
treatment
Control Group
would be the
group that contains the test
subjects, the individuals being
provided the treatment
Experimental Group
a part of an experimental
Variables
variable
that is changed
Independent Variable
is the
variable being tested
Dependent Variable
that can
be measured in numbers
Quantitative Data
information that
isn’t numbers
Qualitative Data
technique of using a sample
Sampling
a small part - to represent the entire population
