Understanding the Scientific Method and Data Analysis

The video tutorial recaps previous instructions and explains how to use the scientific method in daily life. It covers the types of data—qualitative and quantitative—and how to organize them into charts, tables, and graphs. The tutorial also explains how to label graph parts and the importance of dependent and independent variables. Finally, it discusses how scientists form conclusions based on data, emphasizing that science disproves rather than proves hypotheses.

What was the example used to illustrate the scientific method in daily life?

• Trying a key in a lock

• Baking a cake

• Planting a tree

• Driving a car

What is the term for information collected during an experiment?

• Control variable

• Independent variable

What do scientists do with a hypothesis based on gathered data?

• Prove it true

• Ignore it

• Support or reject it

• Publish it immediately

In science, what is the focus when forming conclusions?

• Proving something is true
