What is an independent variable?

Back

An independent variable is the factor that is changed or controlled in an experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

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

Front

In an experiment, what does the term 'control' refer to?

Back

The control is a standard against which the results of an experiment are compared, ensuring that the test is fair.

Front

What is the purpose of a hypothesis in scientific experiments?

Back

A hypothesis is a testable prediction about the relationship between the independent and dependent variables.

Front

What is the Y-Intercept in a graph?

Back

The Y-Intercept is the point where a line crosses the y-axis, representing the value of the dependent variable when the independent variable is zero.

Front

How does changing the independent variable affect the dependent variable?

Back

Changing the independent variable can cause changes in the dependent variable, which is the basis for testing hypotheses in experiments.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities (e.g., color, texture), while quantitative data involves numerical measurements (e.g., height, weight).

Front

What is a controlled experiment?

Back

A controlled experiment is one in which all variables are kept constant except for the independent variable, allowing for a clear cause-and-effect relationship.

Front

What is the significance of replicating experiments?

Back

Replicating experiments is important to verify results and ensure that findings are reliable and not due to chance.

Front

What is a variable in scientific research?

Back

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