Study Notes

What is and isn't research?

Research is a systematic and methodical process of gathering information, analyzing it, and drawing conclusions to create or validate knowledge.
Research aims to answer specific questions, address issues, or solve problems, deepening understanding of a subject.
Simple data collection without a plan or analysis is not research.
Anecdotal observations or routine problem-solving without systematic study are not research.
Compiling facts without analysis is not research.
Biased or unsystematic approaches are not research.

What is Research?

Research involves structured inquiry with defined steps, methods, and objectives.
It focuses on specific questions or hypotheses, exploring areas of uncertainty or new knowledge.
It relies on empirical evidence (observable and measurable data).
Research results are reproducible by others.
Research contributes new knowledge or improves existing understanding.

Evidence-Based Practice (EBP)

EBP is a decision-making approach that combines best available research evidence, clinical expertise, and patient values to achieve effective outcomes.
EBP is commonly used in healthcare, education, and other fields.
Key components of EBP include the best research evidence, clinical expertise, and patient values.

Steps in Evidence-Based Practice

Ask a clear, answerable question.
Collect best available evidence.
Critically appraise the quality of evidence.
Integrate evidence with clinical expertise and patient values.
Assess the outcomes of the decision and make adjustments as required.

The Research Process

The research process is cyclical, with new questions often arising from completed studies.
It refines methods, improves knowledge, and fosters continuous learning.

Different Kinds of Decision-Making

Strategic decisions guide the overall direction of organizations.
Tactical decisions implement strategic plans.
Operational decisions ensure daily function.
Programmed decisions follow established guidelines.
Non-programmed decisions require custom solutions.

Different Forms of Scholarly Work

Original research articles report new findings from empirical studies.
Review articles summarize and synthesize existing research.
Case studies provide in-depth analysis of specific cases.
Theses and dissertations are original research projects submitted for academic degrees.
Conference papers and proceedings share research findings at conferences.
Book chapters or books provide comprehensive coverage of topics.
Technical reports document research results.
White papers inform policy or industry.
Editorials and commentaries provide expert opinions.
Patents protect new inventions.
Datasets and databases are sources of raw data for secondary analysis.

Qualitative Research Paradigms

Constructivism: Knowledge is co-created with participants.
Interpretivism: Understanding human behavior from individuals' perspectives.
Phenomenology: Understanding lived experiences.
Critical theory: Examining social inequalities and power dynamics.
Feminist theory: Addressing gender inequality.
Postmodernism / Poststructuralism: Deconstructing existing beliefs.
Pragmatism: Focusing on practical solutions and applicability.

Bias in Research

Quantitative research bias: Sampling bias, selection bias, measurement bias, confirming bias, attrition bias, overfitting.
Qualitative research bias: Researcher bias, selection bias, social desirability bias, interviewer bias, respondent bias, cultural bias, theoretical bias, Hawthorne effect (Observation bias).

Validity and Reliability in Research

Validity refers to the accuracy and truthfulness of a measurement or study.
Reliability refers to the consistency and stability of a measure or study.
Types of Validity include: Internal Validity, External Validity, Construct Validity, and Content Validity.
Types of reliability include: Test-retest reliability, inter-rater reliability and internal consistency.

Hypothesis Testing

Null Hypothesis (Ho): There is no effect or relationship.
Alternative Hypothesis (H1 or Ha): There is an effect or relationship.
Test Statistic: A calculated value used to determine whether to reject the null hypothesis.
Significance Level (α): The probability of rejecting the null hypothesis when it is true.
P-value: The probability of obtaining results as extreme as the observed results assuming the null hypothesis is true.
Critical Value: A threshold used to determine whether a test statistic is significant enough to reject the null hypothesis.

Types of Errors in Research

Type I Error (False Positive): Rejecting a true null hypothesis.
Type II Error (False Negative): Failing to reject a false null hypothesis.

Experimental vs. Non-Experimental Research

Experimental research: Manipulates an independent variable to observe effects on a dependent variable, high control over variables, ideal for cause-and-effect.
Non-experimental research: Observes or measures variables without manipulating them, often used for associations or correlations, typically more naturalistic.

Cross-Sectional vs. Longitudinal Research

Cross-sectional: Collects data from a population at a single point in time.
Longitudinal: Collects data from the same individuals over an extended period.

The GRADE Framework

Grades quality of evidence into categories (High, Moderate, Low, Very Low).
Classifies recommendations (Strong, Weak/Conditional).
Considers multiple factors (risk of bias, inconsistency, indirectness, imprecision, publication bias).

Data Collection Methods

Quantitative: Surveys, experiments, observations
Qualitative: Interviews, observations, case studies
