Course of Study for Statistics
Scope and Sequence – Statistics is an elective course wherein students are introduced to major theories and techniques for
collecting, analyzing, and drawing conclusions from data. Students in this course will be exposed to three broad conceptual
themes: exploring data, planning a study, and anticipating a pattern in advance. The direct application of statistical
techniques on standard problems and the analysis of graphical representations will be emphasized. Technology will be used
to develop understanding.
More class time will be used to practice the basic concepts of the course. It is open to students in Grades 10-12.
The prerequisite is one year of Algebra 2 with a C average or better.
Course Overview: The General Organizational for this Course
Unit numbers correspond to sub-chapter numbers in our textbook.
Exploring Data: Describing patterns and departures from patterns (~40%) Exploratory analysis of data makes use of graphical and
numerical techniques to study patterns and departures from patterns. Emphasis will be placed on interpreting information from
graphical and numerical displays and summaries. This theme is covered in Chapters 1-4 of this course.
Sampling and Experimentation: Planning and conducting a study (~20%) Data must be collected according to a well-developed plan
if valid information on a conjecture is to be obtained. This plan includes clarifying the question and deciding upon a method of data
collection and analysis. This theme is covered in Chapter 5 of this course; ideas regarding planning and conducting a study are
presented in Chapter 4 as well.
Anticipating Patterns: Exploring random phenomena using probability and simulation (~40%) Probability is the tool used for
anticipating what the distribution of data should look like under a given model. This theme is covered primarily in Chapters 7-9 of
this course; the t distribution is covered in Chapter 10.
