The word that best fits the definition of an objective and systematic way of collecting information and arriving at conclusions is the scientific method.
The scientific method was popularized as a term in the 19th century when scientific developments were rigorously taking place. The scientific method is an empirical process of experimentation and observation with high skepticism for observations. Skepticism in observation is frequent as assumptions could misinterpret the results.
The scientific method starts with observing and researching the topic. It further formulates a hypothesis by induction. It tests the hypothesis by experimenting and analyzes the data recorded after experimentation.
The analysis of data is then transformed into a report and conclusions of the experiment. These experiments are conducted to empirically study whether the findings contrast or agree with the hypothesis.
