Experimental Design

Experimental Design is a method used to plan and conduct experiments in a way that ensures valid and reliable results.

An Independent Variable is the factor that is changed or manipulated in an experiment to observe its effects.

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

A Hypothesis is a testable statement predicting the relationship between the independent and dependent variables.

Having only one independent variable helps to isolate its effects and ensures that the results are valid.

A Control Group is a group in an experiment that does not receive the treatment or independent variable, used for comparison.

A Testable Question is a question that can be answered through experimentation and observation.

Variables are factors that can change in an experiment, and they help to determine the relationship between the independent and dependent variables.

Qualitative data describes characteristics or qualities, while quantitative data involves numbers and measurements.

A Conclusion is a summary of the results of an experiment, explaining whether the hypothesis was supported or not.
