Part 1: The Quantitative Research Question
Q1. How prevalent is the risk factor of falls in older persons compared to other age groups?
Part 2: Quantitative Methods and Data Collection
Relevant Quantitative Methodologies
The objective of quantitative research is to obtain numerical or statistical data to analyze the impact of a phenomena. For this case, the phenomenon being studied is falls and trauma. To find out the prevalence of falls in hospitals especially among older persons, the appropriate methodology chosen is survey research (Creswell & Creswell, 2018). The advantages for choosing survey research for this study draws from the fact that surveys are extensive and dependable. Using surveys, as McCall (2018 Quantitative Research Questions and Methods) observes, the researcher can get the opinion/answers of a large population sample giving an accurate picture of the phenomenon being studied. For this research, I choose survey for the reason that it gives precise results. Accurate data is critical in research work because the credibility of the research lies with the quality of data collected. Surveys are ideal for scientific research studies because they provide all the participants with a standardized stimulus. With such high reliability obtained, the researcher’s own biases are eliminated.
Quantitative Data Collection Tools or Strategies
The most common tools or strategies used for data collection in quantitative study are observations, questionnaires, focus groups, and interviews. Questionnaires are by far the most used instrument for collecting data in quantitative research (Jones, Gwynn, & Teteer, 2019 Quantitative Research Questions and Methods). They are basically a set of structured/standardized questions used to collect data from research participants (Grants, 2018). Conversely, focus groups are a group of people/participants chosen by a researcher to get their perceptions/experiences. For this study, questionnaires will be used since a large number of participants is targeted. Interviews are data collection approach where the researcher individually sits down with chosen participants and asks them questions about the phenomenon being studied. Interviews are important in research because the researcher acquires first-hand information from research participants.
The Importance of Methodologically Relevant Data Collection to a Research Plan
Data collection is a critical step in research that must be done with care. The results and findings of a research rely on data collected. This factor mean that incorrect data may result in inaccurate findings while the opposite is also true. Besides, as Nardi (2018 Quantitative Research Questions and Methods) notes, the overall reliability of a research depends on the quality of data gathered. All decisions of a research also depend on the data collected. For example, a researcher can work on his/her hypothesis based on the data they have gathered. Lastly, accurate data help researchers to accurately answer the research questions (Xu, & Hickman, 2020). When research questions are answered correctly based on the gathered data, the researcher easily achieves the objective of the research.
For this research, surveys will be used to explore the phenomenon of falls and trauma. The research will encompass a large number of participants across different healthcare facilities to get a good picture about falls and trauma in healthcare facilities. Some of the benefits for choosing survey for this research is that it gives accurate results, good statistical significance due to high representativeness, the fact that surveys give researchers a good degree of flexibity.
