Introduction to Research Methods

Identify key issues and debates, and uncover gaps to develop a focused research question. Evaluate literature quality, summarize and synthesize findings, and craft a coherent narrative with proper citations.

Explore PubMed, free online biomedical database from Ncbi, NIH, using mesh terms and clinical queries in advanced search to find articles by title or abstract on exercise and weight loss.

Learn how to design rigorous research by defining focused questions and hypotheses, choosing data collection and analysis methods, and selecting designs such as experimental, cross-sectional, or longitudinal, and sampling considerations.

Learn how the PICOT mnemonic frames clinical questions by identifying population, intervention, comparison, outcomes, and time, guiding focused research and the development of clinical questions.

Understand that a research hypothesis is a specific, testable statement made before a study and tested with collected data.

Identify and select research variables by aligning with the research question, theory, and literature, ensuring feasible, measurable instruments, controlling extraneous variables, and operationalizing definitions.

Explore data collection methods such as surveys, interviews, observations, and experiments, and learn to plan, collect, manage, ethically obtain informed consent, and evaluate data for reliable results.

Explain how independent and dependent variables interact: the manipulated independent variable and the measured dependent variable, illustrated by sleep deprivation affecting test scores, with controls for other factors.

Explore data management tools that organize, collect, store, and manage data, including SQL, SAS, Excel, DBMS, data warehouses, data marts, and analytics tools, to improve efficiency and make better decisions.

Explore data analysis from cleaning and organizing data to choosing methods and reporting results, using descriptive, inferential, and qualitative statistics with visualization techniques.

Compare parametric and non-parametric statistics, outlining distribution assumptions, power under correct assumptions, robustness to violations, and typical tests such as t tests, ANOVAs, regression, Wilcoxon, Mann-Whitney, and chi-square.

Explore how machine learning and artificial intelligence drive data analysis across fraud detection, risk assessment, product recommendations, and sentiment analysis, with attention to data quality and bias.

Master data reporting by selecting appropriate report types and presenting research findings clearly. Tailor the report to the audience and purpose, using visuals, tables, and concise, objective writing.

Explore the research paper structure, from abstract and introduction to methods, results, discussion, and conclusion, and learn to frame the research question, describe data methods, present results, and discuss implications.

Peer reviewed journals evaluate research quality by two or more experts not connected with the author before publication, ensuring originality, significance, and validity, and providing authors with feedback to improve.

Explore ethics in research by examining respect for persons, autonomy, beneficence, justice, confidentiality, and transparency, applying informed consent and methods to avoid plagiarism and protect participants.

Trace the modern history of research ethics from the Nuremberg Code to the Common Rule, highlighting informed consent, the right to withdraw, and harm prevention.

Exposes major ethical violations of the Tuskegee study and reshapes informed consent, the right to withdraw, and protections for human subjects in United States research.

Learn to format references and in-text citations using APA, MLA, Chicago, Turabian, or IEEE styles, and compile a complete reference list or bibliography for your research.

Learn to craft a clear, persuasive research proposal that outlines your question, methods, data analysis, timeline, and budget, while reviewing literature gaps and ensuring feasibility and professionalism.

Explore how major research institutions fund proposals through diverse grant programs, from NIH and NSF to DOD and private foundations, and tailor well written proposals to eligibility and funding priorities.

Explore how the digital age reshapes research, offering easier access to information, global collaboration, and wider sharing of findings, while addressing challenges like fake news and privacy concerns.

Assess why 'do your own research' is misused by anti-science voices in the covid era and why evaluating scientific evidence requires expertise; consult qualified experts to understand science.

Review the research process from defining the problem to communicating results. Examine data collection and analysis methods, including surveys, interviews, experiments, observations, and ethics.
