Disadvantages of the Quantitative Research
Despite the benefits of quantitative research, it is sometimes inadequate in explaining complex research topics.
Using precise and restrictive operational definitions may inadequately represent complex concepts. For example, the concept of mood may be represented with just a number in quantitative research, but explained with elaboration in qualitative research.
Predetermined variables and measurement procedures can mean that you ignore other relevant observations.
Despite standardized procedures, structural biases can still affect quantitative research. Missing data, imprecise measurements or inappropriate sampling methods are biases that can lead to the wrong conclusions.
Quantitative research often uses unnatural settings like laboratories or fails to consider historical and cultural contexts that may affect data collection and results.
