When you think positivism, think hard sciences (mathematics, physics, biology, astronomy, etc).
Positivism is based on the belief that knowledge can be obtained through objective observations and measurements. In other words, the positivist philosophy assumes that answers can be found by carefully measuring and analysing data, particularly numerical data.
As a research paradigm, positivism typically manifests in methodologies that make use of quantitative data, and oftentimes adopt experimental or quasi-experimental research designs. Quite often, the focus is on causal relationships.
In other words, understanding which variables affect other variables, in what way and to what extent. As a result, studies with a positivist research philosophy typically aim for objectivity, generalisability and replicability of findings.
