Mastering core scientific research concepts is critical for advanced academic research and examinations (UGC NET, KSET, Ph.D. Entrance). Here is an overview of the core principles before you take the test:
1. Cross-Sectional vs. Longitudinal Data (ಅಡ್ಡ-ವಿಭಾಗೀಯ ಮತ್ತು ರೇಖಾಂಶದ ದತ್ತಾಂಶ)
Cross-Sectional Data is collected from sample units at a single point in time to measure prevalence or relationships. Longitudinal Data observes the same cohort across multiple chronological intervals to determine causal pathways and trends over time.
2. Deductive Reasoning (ನಿಗಮನ ತಾರ್ಕಿಕತೆ)
Deductive Reasoning is a top-down logical approach moving from universal theories and premises to operationalized hypotheses, which are subsequently confirmed or falsified through empirical observation.
3. Determinism in the Positivist Paradigm (ನಿಯತಿವಾದ ಮತ್ತು ಪ್ರತ್ಯಕ್ಷ ಪ್ರಮಾಣವಾದ)
Determinism assumes that natural and social phenomena do not occur by pure chance; rather, they are systematically produced by identifiable antecedent factors. This forms the cornerstone of quantitative positivism.
4. Directional Hypothesis (ನಿರ್ದೇಶಿತ ಕಲ್ಪನೆ)
A Directional Hypothesis explicitly predicts the orientation of an effect or difference (e.g., stating values will be “greater than”, “less than”, or “positively associated”), requiring a one-tailed statistical significance test.
