Characteristics of Qualitative and Quantitative Research Designs.



When evaluating quantitative data keep in mind that the data are numerical. This type of research evaluates the participant’s opinions and attitudes by testing a theory or hypothesis. The attributes that should be appraised when using quantitative method, when numerical data is collected it can be incorporated into the research in order to evaluate the hypothesis.  Whereas, qualitative data is non-numerical and uses data gathered through interviews, observations and surveys.

One characteristics of qualitative method, is the researchers who analyzed the collected data identifying themes, patterns and relationship Schmidt & Brown (2018). De Clark (2017) illustrated that qualitative understanding of dimensions as reflecting the nature of physical quantities, and the new, quantitative conception based on unit conversion and measurement. Quantitative research method is done to provide information on what is happening, while qualitative is done to show why what is being researched happened (Schmidt & Brown, 208).                                                         Reference De Clark, S. G. (2017). Qualitative vs quantitative conceptions of homogeneity in nineteenth century dimensional analysis. Annals of Science, 74(4), 299–325. Schmidt, N. A., & Brown, J. M. (2018).

Qualitative Research

Qualitative research is carried out on items that cannot be accurately measured. It involves the usage of non-statistical approaches in data entry. Investigations or analyses are done using sensory techniques, such as observations, in gathering information and data organization into patterns (Roulston, 2019).

Quantitative Research

Quantitative research is a study carried out on items precisely measured to give out an output. It involves using statistical values, such as percentages, means, standard deviations and numbers (Knapp, 2017). For instance, a researcher may decide to conduct a study and determine that fifty percent of patients in a hospital die during childbirth. In this case, the quantitative research will be defined by fifty percent. Therefore, this type of research is used to describe life situations, giving them a precise meaning.

Characteristics of Qualitative and Quantitative Research Designs.

Qualitative Research Design

This type of research design uses words in its description, unlike the quantitative method, which uses numbers. Therefore, qualitative research design lacks both the independent and dependent variables in its analysis. Consequently, this makes the research design non-experimental. Furthermore, qualitative research design provides several data collection points at a given time, which brings about the difficulty in developing its hypothesis and making group comparisons.

Quantitative Research Design

The data in quantitative research design is collected using instruments, such as questionnaires, surveys, and data flow diagrams. The finding in this design is focused on particular population sample sizes. In addition, the method uses numbers in the analysis of specific behaviours of the study population. The study is also reliable, and this makes it flexible to be repeated. Since data is collected in the form of numbers, it can be arranged and analyzed in figures, tables and charts. Furthermore, quantitative research design can be used to describe a wider population.

An Example of Qualitative and Quantitative Research Designs.

In analyzing the experience of hope in women facing challenges during childbirth, semi-structured interviews can be used in the data collection. The data can also be recorded in groups, thus making it a qualitative research design. On the other hand, when analyzing the effect of body exercise on blood pressure levels, numbers can be used to measure the blood pressure levels and data entry in charts, figures, or tables, thus making it a quantitative data analysis.
