Quantitative research is concerned with the calculation of observation results. Quantitative data is any data presented in a numerical format, such as statistics, percentages, etc. Causal-comparative research is done primarily to explain and better understand the causal processes involved in creating an event, feature, or relationship, usually by bringing together variations in the explanatory variable or variables. Correlation is a study conducted to confirm or disprove a hypothesis about a statistical relationship between several (two or more) variables.
In experimental research, the researcher actively intervenes in the study process to gain specific knowledge about it. The phenomenon under study is observed here in specially created and controlled conditions, which allows reproducing the course of the phenomenon when similar conditions are repeated. In a research survey, one or more groups are involved, where persons are selected at random.
Qualitative research is a research method through which it is possible to get in-depth and detailed information about the subject of study. Qualitative research methods are aimed at obtaining the most complete and detailed information about the object of study. The main difference between the two methods is that qualitative methods do not focus on statistical assessments and measurements but are based on understanding and interpreting empirical data. There are five types of qualitative research methods in nursing. With the help of ethnography, the researcher can be involved in consideration of the order of the subjects (Armstrong, 2017). In the narrative approach, the researcher collects data from one or more topics by interviewing and documenting over some time. Phenomenology is used to study activity and results from several angles. Grounded theory is used to examine social processes within a social setting. Additionally, a case study allows you to get a more detailed and in-depth analysis of a specific object.
