Fair tests
• If it’s a fair test it’s repeatable. • So you can always repeat a test and always
come out with the same results. • Controls Variables.
Variables
• IV- Is what is changing.• DV- The effect.• CV- Stays the same. • Ex) Does the amount of water effect the
growth of a plant?• IV- Amount of water• DV- Height
Observations
• Something you notice, to formulate a test. (hypothesis)
• Ex) -The room is cold.• -Very sunny outside. • -A lot of people are wearing jeans today.
Conclusions
• Logic.• Rephrase the question.• Summarize the main ideas.
Bar/Line graphs
• Bar graphs- No time involved.• -Comparing things. • Line graphs- Show change over time.• -Pattern in our data.
Qualitative/Quantitative statements
• Qualitative does not involve numbers. • -Her shoe is untied.• Quantitative evolves numbers.• -There are 23 students in this class.
Mean, Median, Mode
• Mean: All #’s added together / by amount of #’s.
• - 1 2 3 4 5=15 : 15/5=3• Median: Middle #.• - 1 2 3 4 5 • Mode: Most repeated #.• - 1 2 3 3 4 5
Hypothesis and Theory
• Hypothesis: Cause and effect statement. (educated guess)
• Theory: Is a hypothesis that is tested many times and the results are the same. (Proven Hypothesis)

• Control: Stays the same.• Experimental: The group that gets tested on.
