1. What is the difference between quantitative and qualitative research

methods in nursing? Provide an example of each type of research.

Quantitative research methods use numerical data to test hypotheses,

measure outcomes, and generalize findings. Qualitative research

methods use non-numerical data to explore meanings, experiences, and

contexts. An example of quantitative research is a randomized

controlled trial that compares the effectiveness of two interventions for

wound healing. An example of qualitative research is a focus group that

explores the perceptions and challenges of patients with chronic pain.

2. What are the main components of a research proposal in nursing?

Explain the purpose and importance of each component.

A research proposal in nursing typically consists of the following

components: introduction, literature review, research question or

hypothesis, methodology, ethical considerations, and budget. The

introduction provides the background and rationale for the study, as

well as the aims and objectives. The literature review summarizes the

existing knowledge and identifies the gaps that the study intends to fill.

The research question or hypothesis states the main problem or question

that the study will address, and the expected results or outcomes. The

methodology describes the design, sample, instruments, procedures, and

data analysis methods that will be used in the study. The ethical

considerations discuss the potential risks and benefits of the study for

the participants and society, and how they will be minimized or

maximized. The budget estimates the costs and resources needed to

conduct the study.

3. What are some common types of sampling methods used in nursing

research? Describe the advantages and disadvantages of each type.

Some common types of sampling methods used in nursing research are

probability sampling and non-probability sampling. Probability sampling

involves selecting participants randomly from a population, so that each
