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.
