Introductory Statistics for Social Sciences Exam Practice Tests
Course Introduction
This course provides an introduction to the fundamental concepts and methods of statistics as applied in the social sciences. Students will explore descriptive and inferential statistics, including measures of central tendency, variability, probability, hypothesis testing, correlation, and regression analysis. Emphasis is placed on understanding the logic behind statistical procedures, interpreting output from statistical analyses, and applying statistical reasoning to real-world social science research questions. No prior knowledge of statistics is required, and the course incorporates practical examples from sociology, psychology, political science, and related fields to illustrate the relevance and application of statistical methods.
