Researcher is the data gathering instrument. Researcher uses tools, such as questionnaires or equipment to collect numerical data. Data is in the form of words, pictures or objects. Data is in the form of numbers and statistics. Qualitative data is more 'rich', time consuming, and less able to be generalized. Quantitative data is more efficient, able to test hypotheses, but may miss contextual detail. Researcher tends to become subjectively immersed in the subject matter.

Researcher tends to remain objectively separated from the subject matter. Qualitative versus Quantitative Research: How many people to ask? In general, it depends on the research method, the approach and the time that is available. Jackob Nielsen, for example, says that five persons in a qualitative study are in most cases enough for a qualitative survey about human centered design questions. Nielsen, He argues that the first interviewed person provides often the most insights.

The second person will provide similar insights and will add some new insights to the research and so on. Most important is the fact, that asking no people in the design process gives no insights to the designer, and the more persons you add, the insights are not getting linear more.

Although mixed methods research is not new, it is a movement that has arisen in response to the currents of qualitative and quantitative research. Designers sometimes argue that tracked datasets are soulless and not a valid input. But when we can combine personal insights gained by qualitative research and combine it with quantitative behavioral data, it will enable designers to ask smarter questions in the design process, or to cite Seemann: Mixing both methods, and adding behavioral data from sensors, we can create a new dimension in understanding people better, by analyzing what people actually do and how they behave, instead of asking them on how they think and feel.

Because what people say, think, and feel can be contradictory to what they actually do. It is not that people are being dishonest, in fact, quite the opposite, they are giving as honest answer as they can.

Where the Quantitative Meets the Qualitative Available at: Sign in Get started. The data collected is numeric, allowing for collection of data from a large sample size.

Statistical analysis allows for greater objectivity when reviewing results and therefore, results are independent of the researcher. Numerical results can be displayed in graphs, charts, tables and other formats that allow for better interpretation. Data analysis is less time-consuming and can often be done using statistical software. Results can be generalized if the data are based on random samples and the sample size was sufficient.

Data collection methods can be relatively quick, depending on the type of data being collected. Numerical quantitative data may be viewed as more credible and reliable, especially to policy makers, decision makers, and administrators.
