This workbook is designed to accompany a co-requisite mathematics course in statistical principles and basic probability theory. As a companion resource, it offers students a solid foundation and understanding of mathematical concepts for success in a college-level, first-year statistics course.

The exercises in this workbook will build mathematical competency in applying number sense, operating with real numbers, solving linear equations and inequalities, evaluating algebraic expressions, analyzing graphs, and critical thinking. Additionally, the content provided will help address the student learning outcomes of communicating mathematically, implementing problem solving strategies, and developing mathematical connections within the context of Introductory Statistics.

With concise, straightforward instruction and multiple guided examples for each section, this workbook can be used in a traditional classroom setting or in tandem with a self-paced approach.
