Publication Bias
The tendency for studies with significant or desirable results to be published more frequently than studies with non-significant or undesirable results.
Big Data
Large and complex datasets collected from various sources, such as social media, online purchases, and company records.
Noise (in Data)
Irrelevant or misleading information in a dataset that can obscure meaningful patterns.
Overspecification
The inclusion of too many variables in a model, leading to overfitting and unreliable predictions.
Correlation vs. Causation
Correlation is when two variables move together, but causation means one variable directly influences another.
Endogeneity
A situation where an independent variable is influenced by the dependent variable, creating a circular causality issue.
Identification Issues
Problems in accurately measuring a concept using available data.
P-Values
A statistical measure used to determine the significance of a result.
Smart Data
High-quality, relevant data that helps answer a specific research question.
Empirical Research
Research based on observed and measured phenomena, rather than theory or speculation.
Deductive Approach
A research method that starts with a theory or hypothesis and tests it using data.
Inductive Approach
A research method that starts with data, finds patterns, and builds a theory.
Research Process
A systematic approach to conducting empirical research.
Hypothesis
A testable statement about the relationship between variables.
Null Hypothesis (H₀)
The assumption that there is no effect or difference between variables.
Alternative Hypothesis (H₁)
The assumption that there is an effect or difference between variables.
Cross-Sectional Research Design
A study that collects data at a single point in time.
Longitudinal Research Design
A study that collects data over multiple time points.
Exploratory Research
A research approach used to explore new ideas or identify potential problems.
Descriptive Research
Research that aims to describe characteristics of a population or phenomenon.
Experimental Research
Research that manipulates one or more variables to test causal relationships.
Ethical Research Considerations
Ethical principles applied throughout the research process.
Anonymity
Ensuring that no individual can be identified from the collected data.
Confidentiality
Keeping personal data private and not disclosing it to unauthorized parties.
