1. Explain the differences between quantitative research and qualitative research. Qualitative research collects non-numerical data to describe events or phenomena. On the other hand, quantitative research uses numeric data with statistical methods to investigate phenomena. (Melnyk & Fineout-Overholt, 2015, p. 609). Qualitative studies address human responses to particular situations or events with an emphasis on interviews and observations. The results are reported from the participant’s point of view. Qualitative studies can be conducted when a phenomenon is unknown to obtain a general idea. Also, they can be used when an event is well known, but certain areas lack details or depth (Melnyk & Fineout-Overholt, 2015). Contrarily, quantitative studies measure phenomena with the use of scales, tests, scores and statistics. Quantitative research designs are multiple. They can range from descriptive studies, which are used to predict relationships between variables, to randomized control trials (RCT). RCTs are used to describe cause and effect relationship between variables. Quantitative studies report results using a uniform format with preselected variables (Melnyk & Fineout-Overholt, 2015).
