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.
