1. What is the difference between quantitative and qualitative research methods? Provide an example of

each type of research in nursing.

- Quantitative research methods involve collecting and analyzing numerical data to test hypotheses or

answer research questions. Qualitative research methods involve collecting and analyzing non-numerical

data, such as words, images, or observations, to explore meanings, experiences, or phenomena. An example

of quantitative research in nursing is a randomized controlled trial to compare the effectiveness of two

interventions for pain management. An example of qualitative research in nursing is a phenomenological

study to understand the lived experiences of patients with chronic illness.

2. What are the main components of a research proposal? Explain the purpose and content of each

component.

- The main components of a research proposal are: introduction, literature review, research question and

objectives, methodology, ethical considerations, and budget and timeline. The introduction provides the

background and context of the research topic, the significance and rationale of the study, and the main

research question and objectives. The literature review summarizes and critiques the existing knowledge and

gaps in the research area, and demonstrates how the proposed study will contribute to the field. The research

question and objectives state the specific aim and scope of the study, and guide the choice of methodology.

The methodology describes the design, sample, data collection methods, data analysis methods, and validity

and reliability issues of the study. The ethical considerations address the potential risks and benefits of the

study for the participants and society, and how they will be minimized or maximized. The budget and

timeline estimate the resources and time needed to conduct the study, and provide a plan for each stage of

the research process.

3. What are some common types of sampling methods in nursing research? Explain the advantages and

disadvantages of each type.

- Some common types of sampling methods in nursing research are: probability sampling, non-probability

sampling, convenience sampling, purposive sampling, quota sampling, and snowball sampling. Probability

sampling involves selecting participants randomly from a defined population, so that each member has an

equal chance of being included. This type of sampling ensures representativeness and generalizability of the

results, but it may be difficult or costly to obtain a complete list of the population or access all the members.

Non-probability sampling involves selecting participants based on availability, criteria, or referral, without

randomization. This type of sampling allows flexibility and feasibility in recruiting participants, but it may

introduce bias or limit generalizability of the results. Convenience sampling is a type of non-probability

sampling that involves selecting participants who are easily accessible or willing to participate. This type of

sampling is simple and inexpensive, but it may not reflect the diversity or characteristics of the population.

Purposive sampling is a type of non-probability sampling that involves selecting participants who have

specific attributes or experiences relevant to the research topic. This type of sampling is useful for exploring

complex or sensitive issues, but it may be subjective or prone to researcher's influence. Quota sampling is a

type of non-probability sampling that involves selecting participants who meet certain quotas or proportions

based on predefined criteria. This type of sampling is helpful for ensuring diversity or representation of

subgroups in the sample, but it may ignore other important factors or variables. Snowball sampling is a type

of non-probability sampling that involves asking existing participants to refer or recruit other potential

participants who meet the criteria. This type of sampling is effective for reaching hard-to-access or hidden

populations, but it may create dependency or homogeneity among the participants.
