Study Notes
Science and the Study of Politics
- Uses critical thinking to analyze the political world
- Combines theoretical scholarship with empirical evidence to understand complex political issues.
- Employs a scientific method to study politics.
- Focuses on understanding the relationship between independent and dependent variables.
Normative and Empirical Analysis
- Normative analysis focuses on how political life should be.
- Empirical research relies on evidence from the real world to understand why political life is the way it is.
- Findings should be reproducible across researchers, methods, and contexts
The Scientific Approach
- Uses a set of principles and rules to guide research.
- Focuses on identifying causal relationships between variables.
- Recognizes that the cause (independent variable) must precede the effect (dependent variable).
Criteria for Causality
- Correlation between the two variables.
- Temporal order: The cause must happen before the effect.
- Absence of confounding variables.
- A plausible causal mechanism that connects the variables.
- Consistency in the relationship across different situations.
Hypotheses
- Predictions about relationships between variables.
- Bridge between political theory and empirical observation.
- Guide research and provide a framework for interpreting evidence.
Measurement
- Assigns numerical values to observations using a defined scale.
- Focuses on both validity (accurate measurement) and reliability (consistent measurement).
- Measurement errors can be systematic or random.
Measurement Errors
- Systematic errors occur when the tool picks up something other than what it's supposed to measure.
- Random errors are chance fluctuations in measurement that don't reflect real differences.
Reducing Measurement Error
- Focus on reliability and validity.
- Use appropriate tools and methods.
Sampling
- Draws conclusions about a larger population (population parameter) based on a smaller group (sample).
- Uses several probability sampling techniques to ensure representativeness and minimize bias.
- Non-probability sampling methods can be used when random selection is not possible.
Population Parameters
- Characteristics of the entire group of interest.
- Estimated using sample statistics.
Confidence Interval
- Range of values within which the population parameter is likely to fall.
- Indicates a certain level of confidence (typically 95%) that the true value lies within that range.
Sample Size
- Determined by the homogeneity of the population, the number of variables, and the desired accuracy.
- Larger samples reduce sampling error and produce more robust results.
- The “law of diminishing returns” suggests that increasing sample size beyond a certain point yields minimal additional benefits.
Probability Sampling Methods
- Simple random sampling: Every member of the population has an equal chance of being selected.
- Systematic random sampling: Selection of every kth person after a random starting point.
- Stratified random sampling: Dividing the population into subgroups and randomly sampling from each group.
Non-Probability Sampling Methods
- Accidental sampling (convenience sampling): Sampling the most accessible or convenient individuals.
- Purposive sampling (judgment sampling): Selecting cases that offer the most relevant or useful information.
- Snowball sampling (network sampling): Using existing participants to identify additional subjects.
- Quota sampling: Stratifying the sample to match the population's proportions.
Inferential Statistics
- Uses sample data to make generalizations about the entire population.
- Allows us to draw conclusions about the relationship between variables.
- Requires understanding of probability theory to accurately interpret findings.
