Scientific Research 1. What is the difference between quantitative and qualitative research methods? Give an example of each. - Quantitative research methods involve collecting and analyzing numerical data to test hypotheses or measure outcomes. For example, a randomized controlled trial to compare the effectiveness of two drugs. - Qualitative research methods involve collecting and analyzing non-numerical data to explore meanings, experiences or perceptions. For example, a focus group interview to understand the barriers and facilitators of medication adherence. 2. What are the main components of a research proposal? Explain the purpose of each component. - A research proposal typically consists of the following components: introduction, literature review, research question, research design, data collection and analysis, ethical considerations, and timeline. - The introduction provides the background and context of the research topic, identifies the knowledge gap, and states the aim and objectives of the study. - The literature review summarizes and evaluates the existing literature on the research topic, identifies the strengths and limitations of previous studies, and demonstrates the significance and originality of the proposed study
