Parts of an Experiment

What is the difference between qualitative and quantitative data?

• Qualitative data involves numerical measurements, while quantitative data describes characteristics or qualities.

• Qualitative data describes characteristics or qualities, while quantitative data involves numerical measurements.

• Qualitative data is always more accurate than quantitative data.

• Quantitative data is subjective, while qualitative data is objective.

How do you identify the dependent variable in an experiment?

• By identifying the factor that is manipulated by the researcher.

• By looking for the factor that is measured or observed in response to changes in the independent variable.

• By determining the initial conditions of the experiment.

• By analyzing the control group results.

What is the significance of a conclusion in an experiment?

• It provides a detailed methodology of the experiment.

• It summarizes the results of the experiment and states whether the hypothesis was supported or not.

• It lists all the materials used in the experiment.

• It describes the background information related to the experiment.

What are controlled variables in an experiment?

• Factors that are manipulated to test their effect on the dependent variable.

• Factors that remain constant throughout an experiment to ensure that the results are due to the independent variable.

• Factors that are measured to determine the outcome of the experiment.

• Factors that vary and can affect the results of the experiment.

What is a scientific method?

• A process for investigating phenomena and acquiring new knowledge.

• A method for conducting experiments without any systematic approach.

• A way to prove theories without evidence.

• A technique for memorizing facts and figures.

What is an independent variable?

• The factor that is manipulated or changed in an experiment to observe its effect on the dependent variable.

• A variable that remains constant throughout the experiment.

• The outcome that is measured in an experiment.

• A variable that is not affected by other variables.

What is the purpose of a control group in an experiment?

• To receive the experimental treatment and measure its effects.

• To serve as a standard for comparison, as it does not receive the experimental treatment.

• To manipulate variables and test hypotheses.

• To ensure that all participants are treated equally.

What is a variable in an experiment?

• A variable is a fixed factor that does not change during an experiment.

• A variable is any factor, trait, or condition that can exist in differing amounts or types in an experiment.

• A variable is the outcome that is measured in an experiment.

• A variable is a type of equipment used in experiments.

What is a dependent variable?

• A variable that is manipulated in an experiment.

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

• A constant that remains unchanged throughout the experiment.

• A variable that does not affect the outcome of the experiment.

How do you identify the independent variable in an experiment?

• By looking for the factor that is intentionally changed or manipulated by the experimenter.

• By identifying the factor that remains constant throughout the experiment.

• By observing the outcome that is measured in response to changes.

• By determining the variable that is affected by the independent variable.
