    Course Description


         Prerequisite(s): Passing grade in Alg. 2/Trig or teacher recommendation.

    Introduction to statistics. Includes sampling; data display; measures of central tendency, variability, and position; random variables; probability; probability distributions; confidence intervals; hypothesis testing; and regression. The content of this course will address the Comon Core Standards set by Arizona State Academic Standards requirements. Periodically, we will review topics from Algebra 1 and Algebra 2 in order to prepare students for post-seconday exams.




    Course Objectives

      • Upon completion of the course, the student will be able to do the following:
    • Define random sampling; design a random sample.
    • Display quantitative data using a variety of tables and graphs.
    • Compute measures of central tendency, variability, and position.
    • Compute simple and conditional probabilities, and determine independence of events.
    • Define a random variable and compute its distribution, mean, and variance.
    • Describe the following probability distributions and their uses: binomial, normal, standard normal, and Student's t, and chi-square.
    • Use a normal distribution when appropriate to approximate a binomial distribution.
    • State and apply the Central Limit Theorem.
    • Determine confidence intervals.
    • Devise and conduct hypothesis tests. Compute Type I and II errors and state their significance.
    • Use analysis of variance.
    • Test for independence using the chi-square distribution.
    • Determine a regression line. Compute the corresponding correlation coefficient and determine its significance.

         Text Book(s)


    The Practice of Staistics, 2nd ed.   Yates, Moore, & Starnes


    Required Materials(OR highly recommended if passing course is your intent)


             A grapher calculator is highly recommended.  The text uses the TI-83/84 (Plus).  Bring in your mannual if you have a different model.  A notebook kept with class activities/data is highly recommended.  Daily assignments will be collected and graded.  Late work is not accepted unless you have an excused absence. These assignments will be graded on completion, neatness,and  logical reasoning about activity.  Quizzes may be announced or unannounced.  Test dates will be on the time line given at end of sylabus.


    Class Conduct


    • Refer to the Student Code of Conduct for additional requirements relating to student behavior.
    • Possession of drugs, alcohol or firearms on school property is illegal.
    • Eating, drinking, and soliciting are not allowed in classrooms. Water is allowed.
    • Telephones, pagers and other electronic devices that distract students are not allowed in classrooms. Graphers are allowed.
    • Students creating disturbances that interfere with the conduct of the class or the learning of others, violations of the Student Code of Conduct, will be referred to the the Dean of Students.
    • Disruptive behavior will not be tolerated and can be cause for being suspended from the class. Disruptive behavior is defined as behavior that is disruptive to the learning process and outside normal behavior parameters. See the Student Code of Conduct for particulars, but examples of disruptive behavior are inappropriate talking, arriving late or leaving early, sleeping or doing other class work in class, etc."


    Class Preparation and Policies


    Students are responsible for their own learning in this class. Students will be responsible for keeping abreast of assignments on their own. Some type of planner (agenda) is highly recommended. All homeworks must be turned in on due date. Late assignments are not accepted.


    Class Attendance

    Students are expected to attend all class sessions. Students are responsible for all material when absent. Please find another person in class to call if absent. No make-up for missed quizzes/tests if absence is unexcused. Students age 18 or older who sign out will have parents called to verify reason for checking out.


    Academic Integrity


    • Students are expected to abide by the Student Code of Conduct. You can find this on school website.




    In order to determine whether this course is meeting its above-stated objectives, a variety of classroom assessment techniques will be used. The purpose of these assessment instruments is to assist your instructor in improving this course. Because this course fulfills a general education requirement, you will be assessed on your ability to communicate both orally and in writing, think critically and demonstrate statistical analysis that is both logical and sound.


    Class Calendar and Assignments:


    Students should expect to 20 to 30 minutes of homework (not including project work) on a daily basis. This work will encompass completion of class activity and/or reading text used in class. All homework and class activities will be collected . Late homework will not be accepted. These will be graded on completion and your logical reasoning. Quizzes may be announced or unannounced. Each semester, there will be at least one long-term project involving the application of the methods discussed in class in order for student to get the experience of applying learned material.
