Statistics‎ > ‎

Course Description

The learning goals in this class are:

  • to develop an understanding of basic statistical concepts.
  • to achieve a competitive score on the mathematics portion of the SAT.
  • to meet the school-wide academic expectations for which the mathematics department is responsible.

At the conclusion of this course, you should know:

  • Data collection methods
  • Graphic representations of data
  • Measures of central tendency
  • Measures of variance and standard deviation
  • Probability and frequency
  • Chi-square
  • Regression lines and correlation
  • Z-scores and normal distribution curves
  • ANOVA's

... and be able to:

  • collect data in a statistically valid way.
  • create appropriate graphs for modeling data.
  • use statistical measures to test a hypothesis and verify the validity of this test.
  • use a mathematical model to predict an outcome based on previous events, and determine the confidence level of this prediction.
  • after using the skills listed above, write reports of findings that can be understood by those who do not know statistics.

These resources will be used to facilitate your achievement of the above goals:

  • Book: Elementary Statistics by Mario F. Triola
  • Internet (homework and other course information can be found at
  • SAT and Accuplacer Practice Problems
  • Computer Presentations 

Assessment methods will include:

  • Tests: These assessments are given at the end of each unit of study.
  • Quizzes: These are more frequent and smaller assessments.
  • Projects: One or two projects will be assigned each quarter. These are usually in-depth, practical applications of recently introduced skills.
  • Homework: Most assignments will be completed using an online homework system called WeBWork (links to this system are on Mr. Grenfell's webpage). If a student does not have access to the internet, he or she can request hard copies of the assignments. Each assignment stays open for multiple days. Questions can be emailed to Mr. Grenfell using the WeBWork system, but these questions may not get answered until the next school day. Because of this, starting an assignment the night before it is due will eliminate extra help opportunities.
  • Midterm and Final Exam

The grades for each quarter will be computed as follows:

  • Tests:          40%
  • Quizzes:      30%
  • Classwork:   10%
  • Homework:   20%

The final grades will be computed as follows:

  • First Quarter:      20%
  • Second Quarter:  20%
  • Midterm Exam:    10%
  • Third Quarter:      20%
  • Fourth Quarter:    20%
  • Final Exam:          10%
