The first step is the
question/problem stage, and is
observing rather than collecting
data
The second step is the research
stage, where one reviews the work
and results of others
The third step is the hypothesis
stage, which must be:
o Educated guess
o Based on gathered
information
o Must be testable
The fourth step is to design an
experiment with a control group,
and only one variable is tested
o Independent variable:
controlled and changed by
experimenter
o Dependent variable:
measured by experimenters
The fifth step is to gather data,
which includes documenting data
and making graphs
o Quantitative data: can be
measured, counted
o Qualitative data:
unmeasured observations
The parts of a graph can be
memorized using the following
acronyms:
o Dependent variable
§ Recorded
§ Y-axis
o Manipulated
§ Independent variable
§ X-axis
o TAILS
§ Title
§ Axis
§ Increments
§ Labels
§ Scale
The last step is to draw conclusions
and theories, and one decides if the
data supports or refuted the
hypothesis and public their findings
