Study Notes

Research Methods

Grounded Theory: discovers problems in a social scene and how people handle them.
Historical Research: describes and analyzes past events.
Nursing Research: a systematic inquiry that develops knowledge about nursing practice, education, and administration.

Measuring Variables

Nominal Scale: classifies individuals, objects, or responses based on a shared property or characteristic.
Ordinal Scale: ranks subgroups in a certain order, with all the properties of a nominal scale.
Interval Scale: has equally spaced units, with an arbitrary starting and terminating point, and all the properties of nominal and ordinal scales.
Ratio Scale: has an absolute zero point, allowing for mathematical operations, and all the properties of nominal, ordinal, and interval scales.

Sampling

Purposive/Judgment Sampling: a non-probability technique where the researcher selects units based on their knowledge and professional judgment.
Slovin's Formula: calculates the sample size (n) based on the total population (N), margin of error (e), and confidence level.

Data Collection

Instruments: Observation, Questionnaires, Interview, Measurement Scales, Likert Scale, Delphi Technique, and Percentage.
Data Saturation: collecting data until no new information is obtained, and redundancy is achieved.

Data Analysis

Measures of Central Tendency: Mode, Median, and Mean.
Measures of Variability: Range, Standard Deviation, Variance, and Percentile.
Measures of Relationship: Pearson's r, Spearman's rho, and Correlation Coefficient.
Inferential Statistics: Chi-Square Test.

Research Process

Conceptual Phase: formulating a research problem, reviewing the literature, and identifying the study's significance.
Empirical Phase: collecting data, conducting pilot studies, and revising the research plan.
Analytical Phase: interpreting the results, and drawing conclusions.
Dissemination Phase: communicating the findings, and utilizing them in practice.

Ethics in Research

Principle of Beneficence: ensuring freedom from harm, and maximizing benefits.
Principle of Respect for Human Dignity: respecting autonomy, providing full disclosure, and ensuring informed consent.
Principle of Justice: promoting fair treatment, and protecting vulnerable subjects.

Research Design

Control: establishing a true relationship between variables by eliminating extraneous factors.
Validity: measuring what is intended to be measured, with internal and external validity.
Reliability: consistency in measuring an attribute.
Causality: assuming cause-and-effect relationships.
Multicausality: recognizing multiple interrelated variables causing an effect.
Probability: the likelihood of an effect occurring after a cause.
