Which type of study involves testing a prediction by manipulating an independent variable and measuring the effect on the dependent variable?

• A. Descriptive studies
• B. Field Experiment
• C. Experimental Studies
• D. Exploratory studies

Answer: (C)

This type of study tests a prediction by manipulating the independent variable and measuring the effect on the dependent variable. By deliberately changing what you think will cause a change and then observing the outcome, you can see whether that manipulation produces differences in the outcome, especially when you use random assignment and a control group to reduce other influences. Descriptive studies only observe and describe variables without changing them. Exploratory studies look for patterns and generate questions without a specific causal prediction. Field experiments are a real-world version of this approach, applying the same manipulation-and-measurement idea in natural settings. The core idea is using deliberate manipulation to establish whether changes in the independent variable cause changes in the dependent variable.
