Pre Statistics (Foundations and Essentials)

Pre-Statistics provides the essential groundwork for anyone beginning their journey into statistics. This course introduces the role and scope of statistics, the mathematical tools needed for further study, and the different types and scales of data. You will also learn to organize, summarize, and visualize data effectively, building a strong foundation for more advanced statistical concepts in future courses.

What you’ll learn

Explain the role of statistics in science, engineering, AI, business, and research.
Differentiate between descriptive and inferential statistics.
Master mathematical prerequisites including sets, logic, functions, algebra review, and basic graphing.
Use summation notation, factorials, and basic combinatorics in statistical contexts.
Classify data as qualitative or quantitative, and identify nominal, ordinal, interval, and ratio scales.
Organize and summarize data with frequency tables, histograms, pie charts, and bar graphs.
Calculate and interpret measures of central tendency and variability.
Create and interpret basic visualizations such as stem-and-leaf plots, boxplots, and scatterplots.
