what is a responding variable

A responding variable is a factor that changes or responds to the effects of the manipulated variable in a scientific experiment. It is also known as the dependent variable, which is what scientists observe for changes or a response to occur. The responding variable can be measured, such as height, weight, or length, or it can be observed, such as emotions, color, or taste. It is important to be able to observe or measure these changes to call a variable a responding variable when designing an experiment. The responding variable is usually named in the title of the project or experiment. Results of the responding variable must be taken without bias or speculation by the scientist, and they need to be measured using objective criteria.
