A data collecting strategy, qualitative—using the five senses, quantitative—counting or using numeric data 8. Define inference
An attempt to explain or interpret observations by using what you observe and/or previous knowledge and experiences, observations what you see infers what you think you see 9. How do you design an experiment?

h. Question
i. Gather information: preliminary observation & scientific literature j. Form a hypothesis
k. Preform a controlled experiment: only one variable is changed l. Record and analyze data: observe qualitative & quantitative data m. Draw conclusions
n. Share conclusions: publish scientific literature & repeated investigation 10. Define hypothesis
A prediction about the relationship between the variables that can be tested If the IV is _________ (describe how you changed it), then the DV will ___________ (describe the change) 11. Variables:

Independent Variable (IV)
The variable that is purposefully changed by the experimenter Dependent Variable (DV)
The variable that responds to what happens with the independent variable Constants (C)
All variables that remain the same *Also known as Controlled variables* 12. Parts of a Design Diagram:
