Guidelines For Using Both Types of Research Ideally, if budget allows, we should use both qualitative and quantitative research since they provide different perspectives and usually complement each other. Because of the involvement of the researcher, not all the members of a target population have an equal probability of being selected to be a part of a sample. Notice that qualitative data could be much more than just words or text. It is used to quantify attitudes, opinions, behaviors, and other defined variables — and generalize results from a larger sample population. Quantitative methods presume to have an objective approach to studying research problems, where data is controlled and measured, to address the accumulation of facts, and to determine the causes of behavior.

. Their findings are collected through a variety of methods, and often, a researcher will use at least two or several of the following while conducting a qualitative study. The distinct feature of is that the researcher focuses on collecting data directly rather than depending on data collected from previously done research. In addition, they do not allow participants to explain their choices or the meaning of the questions may have for those participants Carr, 1994.

The data is then carefully collected from only those people who are most relevant to the objectives of the study.
