Inferences

• It’s a logical explanation. • Known or Assumed to be true.• A turtle has a shell; To protect it’s self.

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/experimental groups

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

(Gets changed)
