What is the main purpose of using instruments or tools in experimental research?

The main purpose of using instruments or tools in experimental research is to obtain consistent and reliable measurements of the variables. Instruments are designed to accurately capture data, allowing researchers to ensure that their findings are valid and can be replicated by others. Consistency in measurement ensures that any changes observed in the dependent variable can be attributed to the manipulation of the independent variable, rather than variations in measurement. This reliability is crucial in producing trustworthy results and making credible conclusions from the research.

While some tools might contribute to simplifying the data collection process or even have an ancillary benefit in creating a visually appealing environment, the essential goal remains the accuracy and reliability of the measurements taken. Therefore, the primary focus in experimental research is always on ensuring that the data is gathered in a systematic way that supports sound scientific inquiry.
