12 Draw a conclusion… Does your data you found support your hypothesis?

13 Additional Vocab to Know… Sampling: using a small sample to represent an entire population ◦ Gallop polls (~1500 people makes a sample) Controlled Experiment: a comparison of a control group vs. experimental group Independent Variable: The variable or factor you control ◦ Which axis? Dependent variable: The variable or factor you measure and cannot control ◦ Which axis?
