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 =15 : 15/5=3 Median: Middle # Mode: Most repeated #
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)
