Studied by 3 peopleControl Group
a group that isn't experimented on, typically used for baseline data
Dependent Variable
the variable that responds to the independent variable, typically where you get data from
Experimental Group

Hypothesis

Independent variable
the changed variable to get results from the experiment
Observation
a careful viewing of something to collect data
Qualitative Data
data that has to do with qualities
Quantitative Data
data that has to do with numbers
Variable
