Researchers need to remain objective. Lab experiments are the most objective method as there is a high level of control
Empirical methods
The idea that knowledge is gained from direct experiences in an objective, systematic and controlled manner to produce quantitative data
Replicability
The ability to conduct research again and achieve consistent results. The findings need to be truly generalised and valid otherwise it will be falsifiable ]
Hypothesis testing
A hypothesis has to be objective and measurable so that at the end of the investigation there is a clear decision that can be made as to whether results have supported or refuted the hypothesis
Paradigms
A set of shared assumptions and methods within a particular discipline
Paradigm shift
if there is a field of study that moves forward through its scientific revolution it can be contradictory and therefore be a paradigm shift
