Quantitative data can tell you which markets are buying honey cereals, which age groups are likely to see your advertising and what your market share is. As health service organisation has become increasingly complex and differentiated across service locations, agencies and sectors, the question of ‘what works’ has expanded to include ‘how it works’ and for whom and the organisational, cultural and professional factors that are necessary to implement and sustain change in routine delivery. The value of qualitative research in policymaking, service development and practice in medicine, in the study of health service organisation and delivery, and in enhancing understanding of health, illness and ageing is increasingly recognised. (Quantitative.) Common reasons for rejecting qualitative papers can be subsumed under three broad areas: relevance for our readership, contribution to knowledge and methodology.

This themed collection of Age and Ageingarticles includes a selection of papers published over the last 10 years which highlights the value of qualitative methodologies in health services research, particularly in understanding patient experience of health and illness and decision making about treatment and preventive care. Quantitative researchers, in turn, might use qualitative methods to generate deeper responses through surveys. Age and Ageing is keen to attract qualitative papers which contribute to understanding of ageing and health and are of practical importance for professionals performing health and care work. This very diversity means, as Patton reminds us, that ‘issues of quality and credibility intersect with audience and intended research purposes’ [18]; such that assessment of the quality of qualitative research cannot simply be reduced to ticking a box on a generic checklist.

Quantitative and qualitative research use different research methodsto collect and analyze data, and they allow you to answer different kinds of research questions. This could be because the research question posed is insufficiently developed or contextualised, or is not located within the relevant conceptual and empirical literature. Both these methods have their advantages and disadvantages, and each of these research approaches is suitable for answering particular types of questions. That would lead you to quota sampling and less strict, rigorous random sampling as you would get in quantitative research. However, other research methods, such as controlled observations and questionnairescan produce both quantitative information. A simple count of qualitative research articles, including qualitative syntheses, published in our journal between 2000 and 2014 found a total of 26, fewer than 2 a year, although there is no consistent pattern over time. Qualitative research gathers data that is free-form and non-numerical, such as diaries, open-ended questionnaires, interviews and observations that are not coded using a numerical system.On the other hand, quantitative research gathers data that can be coded in a numerical form. The qualitative research is conducted to understand a concept about human behavior, whereas quantitative research is conducted to collect factual data about social phenomena. A common problem is that the sampling strategy pursued is not primarily geared to securing richness of information, as for example with ad hoc sampling, insufficient sample size to address the research problem and simplistic assertion of ‘saturation’ to justify sample size [21, 22]. Main Difference – Quantitative vs Qualitative Research Quantitative and qualitative research methods are two general approaches to gathering and reporting data. Others include lack of clarity or inconsistency in the approach to analysis (for example, the methods section refers to use of a grounded theory approach, but the findings are couched in terms of themes); or the findings are devoid of depth and nuance suggesting either under-analysis or thin data.
