Empirically minded philosophers assume that the evidential value of an observation or observational process depends on how sensitive it is to whatever it is used to study. Other data may need to be accommodated by replacing or modifying one or more experimental laws or adding new ones. Here are some examples of statistical assumptions.

Method The authors initiated a program of direct observation of residents' teaching during work rounds during the academic year 2007—2008. They further suggest that the research findings be shared with the community to ensure accuracy of findings. Giving feedback in medical education: verification of recommended techniques.

He pays attention to the kinds of elevators and the dates they were inspected. Using Excel Microsoft Corporation, Redmond, Washington or another spreadsheet package, make two columns of data.

While ethnographers traditionally tried to understand others by observing them and writing detailed accounts of others' lives from an outsider viewpoint, more recently, sociologists have taken a more insider viewpoint by studying groups in their own cultures. Furthermore the development and application of a scientific theory typically requires collaboration and in many cases is promoted by competition.

Under normal circumstances investigators know that their thermometers are sensitive to temperature, and their pressure gauges, to pressure. If epistemic trustworthiness requires certainty, this requirement favors the phenomenalists.
