Scientific techniques are systematic methods used to investigate phenomena, acquire new knowledge, or validate existing theories. These techniques include experiments, observations, and measurements, allowing scientists to gather data and analyze results. Common tools used in these techniques are microscopes, spectrometers, and computers. In addition to experiments, scientific techniques also involve statistical analysis to interpret data accurately. This helps researchers draw meaningful conclusions and make predictions. Techniques such as surveys, field studies, and modeling are also employed to explore various scientific questions across disciplines like biology, chemistry, and physics.
