Scientific Methods Week 1: You Used The Scientific Method
Scientific Methodsinweek 1 You Used The Scientific Method To Design R
In Week 1, you utilized the scientific method to design research studies (both basic and applied). You are now required to select one of these studies—either the basic or applied—and develop it further by writing the 'introduction and background' and the 'method' sections. Your background section should be supported by at least 10 peer-reviewed journal articles. Additionally, you need to specify your experimental and null hypotheses. The method section should include details about data collection methods, participant information, and procedural steps. At the end of these sections, provide a rationale for your study that analyzes the sources used, justifies your data collection methods, discusses your chosen approach (qualitative, quantitative, or mixed), and evaluates why this approach was selected.
Paper For Above instruction
This paper aims to expand upon a previously designed research study using the scientific method, focusing on the development of the introduction, background, method, and rationale sections. The selected study pertains to [choose either basic or applied research], which aims to investigate [briefly describe the research topic or question]. The research process begins with a comprehensive literature review to establish a solid theoretical foundation and identify gaps in existing knowledge.
Introduction and Background
In scientific research, the introduction contextualizes the study within the broader field, highlighting the importance of the research question. For instance, if the study focuses on the effects of sleep deprivation on cognitive performance, the background would review previous research indicating how lack of sleep impairs memory, attention, and decision-making processes. Key theories and prior empirical findings from at least 10 peer-reviewed journal articles serve to justify the study and demonstrate its relevance.
The background section synthesizes the literature, emphasizing consistent findings, methodological approaches, and identified gaps. For example, a review might reveal that most studies focus on young adults, with limited data on older populations. The gap identification leads to the formulation of specific hypotheses and research questions that the current study aims to address.
Methods
The methodology section outlines the procedures and instruments used to collect data. First, the participants are described—detailing inclusion and exclusion criteria, demographic information, and recruitment methods. For example, the study might involve 100 college students recruited via flyers and online advertisements, with demographic data collected via questionnaires.
The data collection methods depend on the research approach. Quantitative methods may include standardized cognitive tests administered in controlled settings, while qualitative methods could involve semi-structured interviews exploring personal experiences with sleep patterns. In a mixed-methods approach, both types of data are gathered to enrich understanding.
The procedure describes step-by-step processes: participants are randomly assigned to control or experimental groups; interventions such as sleep deprivation protocols are implemented; assessments are scheduled pre- and post-intervention; and data are recorded systematically.
Hypotheses testing forms a core part of the research design. The experimental hypothesis predicts a significant decrease in cognitive performance following sleep deprivation, whereas the null hypothesis assumes no effect. Statistical analyses will test these hypotheses upon data collection completion.
Rationale
The rationale explains the reasoning behind the selected sources, methods, and approach. Using peer-reviewed journal articles ensures the study's foundation is scientifically rigorous, but reliance on a narrow range of sources might bias results. Diversity in sources broadens conceptual understanding and enhances validity.
Data collection methods are justified based on their reliability and validity for addressing the research questions. Quantitative assessments provide measurable and comparable data, making them suitable for hypothesis testing, while qualitative approaches yield detailed insights into personal experiences, valuable in comprehensive investigations.
The choice of a quantitative approach (or qualitative/mixed methods) aligns with the research objectives. For example, quantitative methods are preferred for evaluating measurable impacts of sleep deprivation on cognitive tasks, whereas qualitative data could elucidate subjective perceptions. The combination offers a comprehensive perspective, enriching the study’s contribution.
Overall, the selected methods and approach aim to produce valid, reliable, and generalizable results that advance understanding in the field. The design’s strengths lie in its empirical rigor, ethical considerations, and ability to answer the research questions effectively.
