Introduction to Statistics in the Psychological Sciences

Introduction to Statistics in the Psychological Sciences by Linda R. Cote Ph.D.; Rupa G. Gordon Ph.D.; Chrislyn E. Randell Ph.D.; Judy Schmitt; and Helena Marvin https://umsystem.pressbooks.pub/isps/... Chapter 1 offers a foundation for understanding statistics in psychology. It defines “statistics” not just as numbers but as methods for organizing, interpreting, and making decisions from data. It emphasizes how misleading interpretations often arise when we ignore context or hidden variables. The chapter then introduces different types of variables (qualitative, quantitative, discrete, continuous) and measurement scales (nominal, ordinal, interval, ratio). Finally, it explains the distinction between populations and samples, and previews descriptive vs. inferential statistics as tools to summarize data and draw conclusions beyond the data collected.
