The scientific method is an empirical method for acquiring knowledge that has been referred to while doing science since at least the 17th century. The scientific method involves careful observation coupled with rigorous scepticism, because cognitive assumptions can distort the interpretation of the observation.
Observation in the natural sciences [1] is an act or instance of noticing or perceiving [2] and the acquisition of information from a primary source. In living beings, observation employs the senses. In science, observation can also involve the perception and recording of data via the use of scientific instruments. The term may also refer to ...
In the philosophy of science, it is sometimes held that there are two sources of empirical evidence: observation and experimentation. [43] The idea behind this distinction is that only experimentation involves manipulation or intervention: phenomena are actively created instead of being passively observed.
Anthropological survey paper from 1961 by Juhan Aul from University of Tartu who measured about 50 000 people. In fields such as epidemiology, social sciences, psychology and statistics, an observational study draws inferences from a sample to a population where the independent variable is not under the control of the researcher because of ethical concerns or logistical constraints.
Observation: The observation of a phenomenon and inquiry concerning its causes. Induction: The formulation of hypotheses - generalized explanations for the phenomenon. Deduction: The formulation of experiments that will test the hypotheses (i.e. confirm them if true, refute them if false).
A causal relationship between the observations and hypothesis does not exist to cause the observation to be taken as evidence, [3] but rather the causal relationship is provided by the person seeking to establish observations as evidence. A more formal method to characterize the effect of background beliefs is Bayesian inference. [5]

Additionally, the term 'inference' has also been applied to the process of generating predictions from trained neural networks. In this context, an 'inference engine' refers to the system or hardware performing these operations. This type of inference is widely used in applications ranging from image recognition to natural language processing.
