Experiment Variables

Front

What is an independent variable?

Back

The independent variable is the factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable.

Front

What is a dependent variable?

Back

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

Front

What is a control variable?

Back

Control variables are the factors that are kept constant throughout an experiment to ensure that the results are due to the independent variable.

Front

What is the purpose of a hypothesis in an experiment?

Back

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

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 scientific experiment?

Back

A scientific experiment is a structured procedure carried out to investigate a hypothesis by manipulating variables and observing the outcomes.

Front

What is the role of replication in experiments?

Back

Replication involves repeating an experiment to verify results and ensure reliability.

Front

What is a variable in an experiment?

Back

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

Front

What is the significance of a control group?

Back

A control group is used as a benchmark to compare the effects of the independent variable, helping to isolate the variable's impact.

Front

What does it mean to analyze data?

Back

Analyzing data involves examining and interpreting the results of an experiment to draw conclusions.
