Study Notes

Research Methodology

Research Conclusion: The final part of research summarizing findings and implications, contributing new knowledge and insights to solve the study's problem.
Research Methodology: A systematic approach to collecting, analyzing, and interpreting research data, detailing methods, techniques, and procedures, highlighting study design and limitations.
Research Instrument: A tool for data collection in a research study, including surveys, questionnaires, interviews, tests, observations, or other information-gathering methods.
Sample: A subset of a population, for example, 100 randomly selected students from a 1000-student population. Simple random sampling ensures equal selection chances within the population (e.g., names in a box).
Validity: Ensuring an instrument measures what it intends to measure. Content validity assesses if the instrument comprehensively covers the intended content.
Test of Difference: Used to find significant differences in a dependent variable across observation groups.
Research Recommendations: Suggestions on best actions based on study conclusions and findings.
Intervention Description: Crucial for replicating studies, identifying number of groups involved before describing conditions or characteristics.
Logical Conclusions: Foundation for informed recommendations based on research findings.
Descriptive Statistics: Mean, appropriate for measuring average interest levels among senior high school students.
Correlational Research: Explores the relationship between two or more variables (e.g., study habits and academic performance).
Cronbach's Alpha: Measuring internal consistency (reliability) of a measure. Ranges from 0 to 1; higher values indicate greater reliability.
Mean: Appropriate for measuring the average level of a variable.
T-test for Dependent Samples: For comparing means of related groups.
Frequency: The number of times a value or category appears in a dataset, providing insights into distribution (e.g., learning modality preferences).
Intervention (treatment): Deliberate manipulation of variables to observe effects on another variable.
Probability Sampling: Ensures each population element has equal or known chance of selection.
Population: The entire group of individuals a researcher studies.
Primary Data: Data collected firsthand by the researcher (e.g., survey questionnaire with a Likert scale).
Descriptive Research: Describing population or phenomenon characteristics (e.g., types and frequency of gadgets used by Grade 11 students).
Pearson Product Moment Correlation: Measuring strength and direction of a linear relationship between two variables.
Interviews: Direct communication between researcher and respondent (in person or by phone).
Face Validity: Assessing if an instrument appears to measure what it intends to measure (logical validity).
Indirect Observation: Observing behavior without subjects' awareness.
Questionnaires: Written questions for independent respondent answers.
Experiment: Exposing subjects to specific treatments to observe effects.

Data Collection & Analysis Methods

Survey Questionnaire Pre-review: Crucial for ensuring clarity, understandability, and effectiveness before distribution.
High Positive Correlation: Indicates a strong, direct relationship between variables (increase in one variable significantly linked to increase in the other).
Hypothesis Testing (T-value): Calculated t-value greater than critical value indicates a significant relationship.
True Experimental Design: Random assignment of subjects to different conditions (e.g., plants to different sunlight conditions for growth observation).
Analysis of Variance (ANOVA): Comparing means across more than two groups.
Research Methodology Section: Details data collection and analysis procedures, including data sources.
