Basic Concepts in Public Health Statistics
Describe the difference between quantitative and qualitative methods. Explain how each are used in public health.






Qualitative and Quantitative Method
Qualitative and quantitative research methods both produce factual, reliable information, which is useful when collecting data in large populations. Commonly, research is naturally categorized as qualitative or quantitative (Rutberg & Bouikidis, 2018). However, these two methods contrast in different ways. They bring different assumptions about research (Hammersley, 2017).
The quantitative method applies the use of numbers and accuracy, while the qualitative method mainly deals with the experience and perception of humans. The main word used in quantitative is “measure,” while the primary term used in the qualitative method is “perception” (Rutberg & Bouikidis, 2018).
A Qualitative Method in Public Health
This method of research has affected public health just as it has in various professions. It has also become increasingly visible and valuable in this field as it has become central to research (Tolley & Mark, 2016). The qualitative method enables various researchers to investigate or traverse issues and behaviors related to public health that cannot be achieved through quantitative method (Armstrong-Moore & Burgoine, 2021). Understanding multiplex issues through this method is easy.
It is usually used in different circumstances; to study cultural and socio-economic issues that affect health and diseases, scrutinize relations between partners in matters involving public health, and traverse how different people and communities understand various health and diseases (Armstrong-Moore & Burgoine, 2021). Therefore, this method helps interpret socio-economic and cultural factors of health and diseases (Armstrong-Moore & Burgoine, 2021).
A Quantitative Method in Public Health
Most public health researchers frequently use the quantitative method to assess variables and analyze their investigations and findings (McLaren, 2017). Quantitative is used to get statistics of people infected by various diseases in public health (Peters & Chernak, 2019). The quantitative method is also used in quantifying public health risks on multiple illnesses (Peters & Chernak, 2019).
