Study Notes

Research Methods

  • Research involves using scientific methods and knowledge to find truths
  • Example: Conducting a survey using scientific basis and systematic methods

Research Components

  • Background of the research: Provides context for the study
  • Research questions: Statements that represent the ideas to be examined in the study
  • Statement of the problem: Identifies the issue being addressed
  • Significance of the study: Explains who will benefit from the study

Variables

  • Independent variable: A variable that has a presumed effect on the other variable
  • Dependent variable: The variable being tested and monitored

Statistical Analysis

  • ANOVA: Used to compare the effect of multiple variables (e.g., 5 different herbs)
  • T-test: Used to compare the means of two groups
  • Chi-square: Used to analyze categorical data
  • Pearson-r: Used to measure correlation between two variables
  • Mode: Used to determine the most favored topic

Research Design

  • Experimental design: Used to study the effectiveness of a community-based health program
  • Correlational research: Determines the extent of a relationship between two or more variables using statistical data
  • Descriptive research: Provides systematic information about a phenomenon

Data Validation

  • Confidentiality: Important for maintaining the results of interviews or group discussions

Research Instruments

  • Portfolio: A collection of student work, used to assess student achievement (e.g., reflective journal on one poem)

Research Limitations

  • Scope and delimitation: Refers to the boundaries of the research study, arising from the researcher's decision of what to exclude
  • Limitations: Parameters that prevent researchers from pursuing further studies due to time and budgetary constraints

Research Ethics

  • Informed consent: Ensures the safety of the researchers and the test subjects
  • Ethics: Refers to the part of the study that ensures the safety of the researchers and the test subjects
