|•• RESEARCH METHODOLOGY••|
Mixed-Effects Models- Combines fixed effects (population-level effects) and random effects (individual-level variability). - Useful in longitudinal and hierarchical data.
Latent Variable Models- Includes variables not directly observed but inferred from other variables. - Examples include latent class analysis and latent growth modeling.
Path Analysis- Extension of regression analysis. - Models direct and indirect relationships between variables.
Quasi-Experimental Design- Resembles experimental design but lacks random assignment. - Includes designs like nonequivalent control group and interrupted time series.
Meta-Synthesis- Integrates findings from multiple qualitative studies. - Provides a comprehensive understanding of a research topic.
Confirmatory Factor Analysis (CFA)- Tests hypotheses about the structure of latent variables. - Confirms if data fits a predefined factor structure.
Item Response Theory (IRT)- Models the relationship between latent traits and item responses. - Used in test construction and psychometrics.
Ecological Validity- Extent to which research findings generalize to real-world settings. - Important for applied research.
Mediation and Moderation- Mediation°° Explains the process through which an independent variable influences a dependent variable. - Moderation°° Examines how the relationship between two variables changes across levels of a third variable.
Longitudinal Data Analysis- Analyzes data collected over time from the same subjects. - Techniques include growth curve modeling and repeated measures ANOVA.
Ethnographic Research- In-depth study of people and cultures. - Involves participant observation and fieldwork.
Grounded Theory- Develop theory grounded in data. - Iterative process of data collection and analysis.
Phenomenological Research- Explores lived experiences of individuals. - Focuses on subjective meanings and interpretations.
Narrative Analysis- Examines stories and personal accounts. - Identifies themes, structures, and meanings.
Experimental Manipulation Checks- Assesses if the manipulation in an experiment was successful. - Ensures validity of experimental findings.
Latent Class Analysis (LCA)- Identifies subgroups within a population based on response patterns. - Used in behavioral and social sciences.
Counterbalancing- Controls for order effects in repeated measures designs. - Ensures each condition appears equally across all participants.
Content Validity- Ensures a measure covers all aspects of the construct. - Assessed by expert judgment.
Ecological Momentary Assessment (EMA)- Collects data in real-time from participants' natural environments. - Reduces recall bias and enhances ecological validity.
Behavioral Coding- Systematically records and categorizes observed behaviors. - Used in observational studies and experimental research.

|••STATISTICS ••|
Multivariate Analysis- Analysis involving multiple dependent and independent variables. - Techniques include MANOVA, multiple regression, and factor analysis.
Structural Equation Modeling (SEM)- Statistical technique for testing and estimating causal relationships. - Combines factor analysis and multiple regression.
Logistic Regression- Predicts the probability of a binary outcome. - Used when the dependent variable is categorical.
Hierarchical Linear Modeling (HLM)- Analyzes data with nested structures (e.g., students within schools). - Accounts for variability at multiple levels.
Survival Analysis- Analyzes time-to-event data. - Commonly used in clinical trials and reliability engineering.
Cluster Analysis- Groups similar data points into clusters. - Methods include k-means and hierarchical clustering.
Discriminant Analysis- Classifies data into predefined categories. - Determines which variables discriminate between categories.
Principal Component Analysis (PCA)- Reduces data dimensionality by transforming variables into principal components. - Highlights the most important variables.
Bayesian Statistics- Incorporates prior knowledge or beliefs in the analysis. - Updates probabilities as new data becomes available.
Non-Parametric Tests- Do not assume a specific data distribution. - Examples include the Mann-Whitney U test, Wilcoxon signed-rank test, and Kruskal-Wallis test

••UNDERSTANDING PSYCHOLOGICAL TESTING••
∆ Classical Test Theory (CTT):
Explanation: Classical Test Theory is a basic theory in psychometrics that helps us understand the reliability and validity of psychological tests. It focuses on the idea that each person's test score consists of two parts: the true score (what the person's ability or trait truly is) and measurement error (random fluctuations in the test score).
Important Points:
A reliable test produces consistent results when administered multiple times to the same individuals.
Validity means the test measures what it's supposed to measure accurately.
Creator: The origins of CTT can be traced back to several statisticians, including Charles Spearman and Louis Leon Thurstone.🔥 2
