Positivism as a philosophy adheres to the view that only “factual” knowledge gained through observation (the senses), including measurement, is trustworthy. In positivism studies the role of the researcher is limited to data collection and interpretation through objective approach and the research findings are usually observable and quantifiable.
According to the principles of positivism, it depends on quantifiable observations that lead themselves to statistical analysis. It has been noted that “as a philosophy, positivism is in accordance with the empiricist view that knowledge stems from human experience. It has an atomistic, ontological view of the world as comprising discrete, observable elements and events that interact in an observable, determined and regular manner” (Collins, 2010, p.38).
Moreover, in positivism studies the researcher is independent form the study and there are no provisions for human interests within the study. Crowther and Lancaster (2008) inform that as a general rule, positivist studies usually adopt deductive approach, whereas inductive research approach is usually associated with a phenomenology philosophy. Moreover, positivism relates to the viewpoint that researcher needs to concentrate on facts, whereas phenomenology concentrates on the meaning and has provision for human interest.
Researchers warn that “if you assume a positivist approach to your study, then it is your belief that you are independent of your research and your research can be purely objective. Independent means that you maintain minimal interaction with your research participants when carrying out your research” (Wilson, 2010, p.10). In other words, studies with positivist paradigm are based purely on facts and consider the world to be external and objective.

The key features of positivism and social constructionism philosophical approaches are presented in the following table by Ramanathan (2008).
|The observer||Must be independent||Is part of what is being observed|
|Human interests||Should be irrelevant||Are the main drivers of science|
|Explanations||Must demonstrate causality||Aim to increase general understanding of the situation|
|Research progresses through||Hypotheses and deductions||Gather rich data from which ideas are induced|
|Concepts||Need to be operationalised so that they can be measured||Should incorporate stakeholder perspectives|
|Units of analysis||Should be reduced to simplest terms||May include the complexity of ‘whole’ situations|
|Generalisation through||Statistical probability||Theoretical abstraction|
|Sampling requires||Large numbers selected randomly||Small numbers of cases chosen for specific reasons|
Alternatively, the differences between positivist and phenomenology paradigms are best illustrated by Easterby-Smith in the following manner:
|Positivist Paradigm||Phenomenology paradigm|
|Basic notions||The world is perceived as external and objective
Independency of the observer
Value-free approach to science
|The world is perceived to be socially constructed and subjective
Observer is considered a part of the object of observation
Human interests drives science
|Responsibilities of researcher||Focusing on facts
Causalities and fundamental laws are searched
Phenomenon are reduced to the simplest elements
Hypotheses formulation and testing them
|To be focusing on meanings
Aiming to understand the meaning of events
Exploring the totality of each individual case
Ideas are developed by induction from data
|Most suitable research methods||Concepts have to be operationalised||Using several methods in order to different aspects of phenomena|
|Sampling||Samples have to be large||Small samples are analysed in a greater depth or over longer period of time|
