The Scientific Standard for Establishing Causality: Controlled Experiments
The scientific standard for establishing that one variable (X) causes another (Y) involves conducting a controlled experiment. In such an experiment, researchers intentionally change X while observing the resulting impact on Y, ensuring that other factors are held constant to confidently attribute the change in Y to the change in X.

Which of the following statements best describes a scientific hypothesis?
When an empirical study's results fail to support a specific hypothesis, the broader theory from which that hypothesis was derived is automatically considered disproved.

A city government launches a large-scale 'Shop Local' advertising campaign to boost sales at small businesses. Six months later, they observe a 15% increase in average revenue for these businesses and conclude the campaign was the direct cause of the increase. From the perspective of a controlled experiment, what is the primary reason this conclusion is potentially flawed?

To establish that a change in one variable causes a change in another, it is sufficient for a researcher to systematically alter the first variable and then observe a consistent change in the second variable.
Match each research scenario with the principle of experimental design it best illustrates or violates.
A researcher wants to test if a new fertilizer increases tomato yield. They prepare two identical fields of tomatoes, but only apply the new fertilizer to the first field. In this setup, the second field, which does not receive the new fertilizer, serves as the ____ ____, allowing the researcher to isolate the fertilizer's true effect from other factors like weather.
