Empirical evidence (the record of one's direct observations or experiences) can be analyzed quantitatively or qualitatively. Quantifying the evidence or making sense of it in qualitative form, a researcher can answer empirical questions, which should be clearly defined and answerable with the evidence collected (usually called data). Research ...
For example, anecdotal evidence from a friend about how to treat a certain disease constitutes empirical evidence that this treatment works but would not be considered scientific evidence. [ 38 ] [ 39 ] Others have argued that the traditional empiricist definition of empirical evidence as perceptual evidence is too narrow for much of scientific ...
For example, the proposition that water is H 2 O (if it is true): According to Kripke, this statement is both necessarily true, because water and H 2 O are the same thing, they are identical in every possible world, and truths of identity are logically necessary; and a posteriori, because it is known only through empirical investigation.
For example, consider estimating the probability among a population of men that they satisfy two conditions: that they are over 6 feet in height. that they prefer strawberry jam to raspberry jam. A direct estimate could be found by counting the number of men who satisfy both conditions to give the empirical probability of the combined condition.
The sample mean (sample average) or empirical mean (empirical average), and the sample covariance or empirical covariance are statistics computed from a sample of data on one or more random variables.
Collection of empirical data; Modeling and analysis of data; Quantitative research is often contrasted with qualitative research, which purports to be focused more on discovering underlying meanings and patterns of relationships, including classifications of types of phenomena and entities, in a manner that does not involve mathematical models.

The history of scientific method considers changes in the methodology of scientific inquiry, not the history of science itself. The development of rules for scientific reasoning has not been straightforward; scientific method has been the subject of intense and recurring debate throughout the history of science, and eminent natural philosophers and scientists have argued for the primacy of ...
An empirical relationship is supported by confirmatory data irrespective of theoretical basis such as first principles.Sometimes theoretical explanations for what were initially empirical relationships are found, in which case the relationships are no longer considered empirical.
