Pure science is when people look for the experiment and it affects people right away. Applied science is when people don’t go looking for the experiment. It doesn’t effect people right away like pure science.

3
An inference is like an educated guess.

5
Observations are anything that you notice. Example: My shirt is white My phone is pink A conclusion is a summary that you write after the experiment that just sums up the experiment.

6
A bar graph is what you use when there is no time being used in your experiment. Example:

7
Line Graph You use a line graph when you DO use time in you experiment. Example:

QualitativeQualitativeQuantativeQuantative A qualitative statement is a statement that doesn’t use any numbers in it. Example: My phone has stripes. The key board has lots of keys. A Quantative statement is a statement that DOES use numbers. Example: My phone has 23 stripes on it. The key board has 70 keys on it.

Mean, Median, and Mode Mean- Is the average of a group of numbers. o Example: 12,22,23,33,22,12,12 Add them 12+22+23+33+22+12+12=136 Then divide by the number of numbers: 7 136/7=19.5 And round to the nearest number… 19.5= 20 The numbers

10
Mean, Median, and Mode Median is the middle number of the numbers. 12,22,23,33,22,12,12 Put them in order least to greatest 12,12,12,22,22,23,33 And count to the middle then you get …. 22

11
Mean, Median, and Mode Mode is the most used… If your numbers are 12,22,23,33,22,12,12 then it should be easy there are three 12’s two 22’s and one 23. so the mode would be 12.

12
Hypothesis- is an if and then statement. Example: If I water plant A more then it will grow faster. Theory- a hypothesis that has bean tested over and over again and proven the same every time.

13
Control and Experimental groups Control group is the group that you don’t do anything to. Experimental group is the group that you expose to the Iv, or what you change.
