Plotting data on a graph helps scientists understand?

• A. The ethical implications of research.
• B. The relationship between variables in an experiment.
• C. The speed of data collection.
• D. The accuracy of measurement instruments.

Answer: (B)

Graphs show how one quantity changes with another. This visual representation makes the relationship between variables in an experiment clear, exposing trends, patterns, and how a response variable varies when you change the other variable. That guiding power helps scientists interpret data, test ideas, and compare with models. Although ethics, data-collection speed, or instrument accuracy are important topics, plotting primarily reveals how variables relate to each other, not those separate concerns.
