In this module, the four approaches to quantitative research are described and examples are provided. A simple hypothesis states the relationship between two variables. The construction of the experiment may be manipulated to produce a specific result, such as skewing the membership of the experimental group.

Results are compared with results from groups not exposed to the variable. A directional hypothesis predicts the relationship between the two variables Burns An associative hypothesis describes phenomenon that occur together, while causal hypothesis describes one phenomenon that causes another Burns The literature review may reach a conclusion about the phenomenon, based upon statistically analyzing the data.
A Quasi-Experimental Design often referred to as Causal-Comparative seeks to establish a cause-effect relationship between two or more variables.
Quantitative research attempts to accumulate numerical data about a specific phenomenon. Problem-solving involves setting goals and identifying solutions while the nursing process involves planning for those interventions.
When deciding on the appropriate approach, the Decision Tree from Ebling Library may be helpful. Quantitative and qualitative approaches.

Qualitative research is about ‘discovery of facts’ and not necessarily hard evidence. Some studies, particularly anthropological studies, are located in a time. First published inNature is the world’s leading multidisciplinary science journal.
Nature publishes the finest peer-reviewed research that drives ground-breaking discovery, and is read by. It is usually more exploratory in nature.
