What are controlled variables in an experiment?

Back

Controlled variables are the factors that are kept constant throughout an experiment to ensure that the results are due to the independent variable. For example, in a plant growth experiment, the type of plant, amount of music, and sunlight are controlled variables.

Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed or manipulated in an experiment to observe its effect on the dependent variable. For example, in a plant growth experiment, the type of liquid given to the plants is the independent variable.

Front

What is the dependent variable in an experiment?

Back

The dependent variable is the factor that is measured or observed in an experiment. It is affected by changes in the independent variable. For example, in a study on pulse rates, the pulse rate of each group is the dependent variable.

Front

What is quantitative data?

Back

Quantitative data involves numbers that are obtained by counting or measuring. It can be used for statistical analysis and can be represented in graphs or charts.

Front

What is qualitative data?

Back

Qualitative data involves descriptive information that cannot be measured with numbers. It often includes characteristics, qualities, or categories.

Front

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

Back

A control group is used as a benchmark to compare the results of the experimental group. It helps to isolate the effect of the independent variable.

Front

What is a hypothesis?

Back

A hypothesis is a testable statement or prediction about the relationship between two or more variables. It is often formulated before conducting an experiment.

Front

What is the scientific method?

Back

The scientific method is a systematic process used for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge. It typically involves observation, hypothesis formulation, experimentation, and conclusion.

Front

What is an experiment?

Back

An experiment is a scientific procedure undertaken to test a hypothesis by manipulating one or more variables and observing the effects.

Front

What is the difference between an independent variable and a dependent variable?

Back

The independent variable is the one that is changed or controlled in a scientific experiment, while the dependent variable is the one that is measured and affected by the independent variable.
