Bias is another word for the operating point -- a dc voltage or current about which the instantaneous value might vary. For example, you can say you applied a "6 V peak-peak AC signal biased at +1 V". In this case the range of the signal would be from -2 to +4 V. You can see the relationship with the everyday meaning of bias, "a tendency or ...

NettetInstrumentation and internal validity. Instrumentation can be a threat to internal validity because it can result in instrumental bias (or instrumental decay). Such instrumental bias takes place when the measuring instrument (e.g., a measuring device, a survey, interviews/participant observation) that is used in a study changes over time. NettetBias exists in all study designs, and although researchers should attempt to minimise bias, outlining potential sources of bias enables greater critical evaluation of the research findings and conclusions.
