Scientific Method

What is a dependent variable?

• The variable that is manipulated in an experiment.

• The variable that is measured or observed in an experiment, which is affected by changes in the independent variable.

• The variable that remains constant throughout the experiment.

• The variable that is used to compare against the experimental group.

What is a control group?

• A group in an experiment that does not receive the experimental treatment and is used as a benchmark to measure how the other tested subjects do.

• A group that receives the experimental treatment to test its effectiveness.

• A group that is randomly selected from the population to ensure diversity.

• A group that is monitored for ethical compliance during the experiment.

What is the Scientific Method?

• A systematic process used for scientific investigation, involving observation, hypothesis formulation, experimentation, and conclusion.

• A random approach to conducting experiments without any structured process.

• A method used exclusively in mathematics for solving equations.

• A technique for making predictions based on past experiences.

Why is it important for a scientific theory to be widely tested?

• To ensure that the theory is reliable, valid, and supported by extensive data from multiple experiments.

• To make the theory more popular among scientists.

• To reduce the cost of scientific research.

• To limit the number of experiments conducted on the theory.

What is data in the context of scientific research?

• Information collected during an experiment, which can be quantitative (numbers) or qualitative (descriptions).

• A collection of random facts that have no relevance to the experiment.

• The theoretical framework that guides the research process.

• The final conclusions drawn from the results of an experiment.

What is a scientific theory?

• A hypothesis that has not been tested.

• A well-substantiated explanation of an aspect of the natural world that is based on a body of evidence.

• An educated guess about a phenomenon.

• A statement that can be proven true or false.

What is the purpose of conducting an experiment?

• To test a hypothesis by manipulating variables and observing the outcomes.

• To gather data without any specific goal in mind.

• To confirm existing theories without any changes.

• To create a controlled environment for random observations.

What is a variable in an experiment?

• A constant factor that does not change during the experiment.

• Any factor, trait, or condition that can exist in differing amounts or types and can affect the outcome of an experiment.

• A specific measurement taken at the end of an experiment.

• A hypothesis that is tested during the experiment.

What is a hypothesis?

• A definitive conclusion drawn from data analysis.

• A testable prediction about the relationship between variables, often formulated as an 'if-then' statement.

• A random guess made without any prior knowledge.

• A statement that cannot be tested or proven.

What does it mean to draw a conclusion in the scientific method?

• To summarize the results of an experiment and determine whether the hypothesis was supported or refuted.

• To formulate a hypothesis based on initial observations.

• To conduct experiments without any prior assumptions.

• To collect data without analyzing the results.
