When designing a scientific investigation, what is the most important reason to state a hypothesis first?

• To impress other scientists

• To make the experiment longer

• To guide the experimental design and methodology

• To guarantee positive results

Why do scientists primarily use the metric system?

• Because it's easier to remember

• Because it's universally standardized and allows for consistent measurements

• Because it's only used in laboratories

• Because it's older than other measurement systems

What is the key difference between an inference and an observation?

• Observations require special equipment while inferences don't

• Inferences are always more accurate than observations

• Observations are what we detect with our senses, while inferences are explanations based on observations

• Only trained scientists can make inferences

What is the most effective way to organize collected experimental data?

• By creating artistic diagrams

• By memorizing the numbers

• By using organized data tables and graphs

• By writing paragraphs
