Pre - Statistics: A Pathway to Elementary Statistics

Class Schedule & Dates

Pre-Statistics is a beginner course in statistics. The course covers the basics of every statistical study; you will design statistical experiments, collect and organize data, arrange the data on tables and charts, analyze the data, and draw conclusions. These require computational aptitude, so the course also covers fractions, proportions, percents, ratios, and solving equations and inequalities. You will practice a variety of visual representations of data as well: histograms and data charts, boxplots, dotplots, and scatterplots.

You will learn something new with every unit. This course is good for anyone who would like understand the statistical studies, charts and graphs published on the media.This class has no transferability to the University of California and California State University systems (UC:CSU) but the next course in line Math 227 Elementary statistics does.

About This Class
  • This course is required of all non-STEM majors - open to all other interested students. This is a lecture-lab class with "hands-on" work in class. This is a preliminary course to Math 227 Elementary Statistics which is a transfer course. Students do not earn academic units for this class but they earn the units in Math 227.
  • The course will provide online lectures with audio-visual materials. Prerequisite: Math 110 or Math 112 or equivalent. Your basic math comprehension should be strong, as you will be doing algebraic calculations involving fractions and decimals. This website has a study guide, not the actual notes.
  • In this course I am using a hands-on learner-centered pedagogical approach that will require your participation, critical thinking, team building, and communication skills. 
  • This class is experiential in nature; you are an active learner rather than a passive note-taker
  • Learning requires interaction with your peers and mentors and to develop your communication skills
  • Learning involves to form and test conjectures and to develop your critical thinking
  • Group interaction and learning will foster engagement and motivation for success
  • My close monitoring of your performance provides you with the extra support you need to succeed
  • This class will significantly increase your quantitative reasoning ability to the level required to complete it successfully and pass Math227 Elementary Statistics.

There will be five TESTS, weekly QUIZZES, weekly HOMEWORK, and a comprehensive and mandatory FINAL EXAM. The lowest test score will be replaced by your final exam score if it is higher than your test score. No make-up exams will be allowed.

  • E-textbook: A Pathway to Elementary Statistics by Jay Lehmann
  • MYMATHLAB Access Code: You can purchase an access code online at A free temporary access code good for two weeks is available. You can get it at the Mymathlab website. If you buy a new book at the LACC bookstore, the access code is packaged free.


  • The key to learn math is to generate and answer questions. Read your notes and make a list of specific questions to ask in class; I will schedule time for questions and answers at the beginning of each class meeting. Plan on spending at least one to two hours per class meeting doing homework, studying the text, and reviewing your lecture notes; keep a list of the points you don't understand and write down questions; be sure you get answers to those questions in class or using the campus resources available.
  • Videos for every lesson are on the Mymathlab website. To watch a video lesson, login to Mymathlab and select Multimedia Library. There are videos for each section of the textbook. Video lessons are available all semester long. You are also encouraged to take notes from the video lessons. Use the video notebook pages found on the link below the Video Lessons.
  • Notes for every lesson are on the Mymathlab website. To work on class notes, select Video Notebook from Multimedia Library There are notes for each chapter of the textbook. Select the chapter you want; a PDF file appears with exercises for each portion of the corresponding video. Print the notes file and write the notes and examples out in your own style. Continue taking notes in class as the lesson is given and more examples are presented.
  • Enroll in Math 100 to use the π shop, FH 104, for one-on-one tutoring.
  • Drop in to the Learning Resource Center for tutoring.
  • Form a study group with two or three classmates and meet several times a week or on weekends in the LACC Library's quiet study rooms.
  • Ask me questions and ask your classmates as well.
  1. The student will determine all antiderivatives of a function.
  2. The student will graph a function using the first and second derivative test.

The time I have set for each chapter and schedule of tests is tentative and may change. Changes to the schedule may be made if and when necessary. I will announce any changes in class and it is your responsibility to keep abreast of them.

  • Homework will be assigned on a weekly basis. You will find the MMLH assignments on the Internet at the Mymathlab website. Each MMLH assignment corresponds with the section lesson; work each exercise on paper and input your answer into Mymathlab.
  • Each homework assignment will stay posted for one week only for you to complete it within that week. Each MMLH assignment is posted on Monday and is available until Sunday at 11:59 pm. All MMLH assignments are to be completed by 11:59 pm on their due date. You are encouraged to take notes from the video lesson and start on the homework as soon as it becomes available.  MMLH assignments are reopened for reviewing one week before the test that covers those lessons. Homework assignments due dates are listed on the Mymathlab website.
  • There is a Mymathlab Quiz (MMLQ) assigned each week. The quizzes give you more practice with the objectives taught during the week. The quizzes also give you practice working problems without knowing if the answers are correct; in other words, taking a quiz is training you for taking the test.
  • Each quiz contains ten selected questions from the sections covered during the week. Each quiz becomes available on Monday and is available until Sunday at 11:59 pm. Each quiz may be taken/retaken up to five (5) times to improve your score until 11:59 pm on the following Sunday. Check quiz due dates on the Mymathlab website.
  • Work each quiz exercise on paper and input your answer into Mymathlab.
  • There are 5 major tests (MMLT) during the semester. There are no makeup tests. Consult the class Calendar for test dates.
  • Tests are taken online on the Mymathlab website. Each test is up on Monday and is due by Sunday; there is only one attempt possible. Before submitting the test, rework test problems and check answers for possible errors; input the answer carefully into Mymathlab; be aware that a mistyped answer will be graded the same as an incorrect answer. MML homework and quizzes have given you plenty of practice inputting answers.

Please see the LACC Standard of Student Conduct for policies on plagiarism, expected behavior, grievances, and scholastic misconduct. Notice that I will not tolerate cheating in any form; if you are found to be cheating you will receive a zero for the assignment, you may also be suspended for the class, or receive a grade of “F” in the class. I will not accept any activities that in any way disrupt other student’s learning; if your behavior disrupts the class you will be reported to the college’s disciplinary office. 

  • You may withdraw from the class up to Friday on the 12th week of the semester. After that, you will remain on the class roster and receive a letter grade for the class.
  • In the event of serious illness or other circumstances beyond a student's control a student must notify the instructor by email or telephone to keep from being dropped. A later meeting can determine if too much work or information has been missed to continue the class. According to LACC procedure a student can be excluded after 5 unexcused absences from this class. It is the student's responsibility to sign the roll sheet for each class meeting - if you do not sign, you will be counted absent. Each week, one unexcused absence counts off ten points and an excused absence (teacher notified) counts off five points. One class absence per semester is given with no points removed.
  • If a student stops attending a class it is the student's responsibility to officially drop the class in order not to receive a failing grade at the end of the semester (can be done through the Online system). Disruptive behavior can result in the expulsion of the student from class. Consult the current Calendarfor its information concerning Holidays, Drop Dates, Registration, etc. It is the students responsibility to follow those dates see next paragraph.
  • Important! Drop Date Information. The deadline to drop without a “W” is the first day of Week 3 (of the semester), OR Monday, February 18 for Spring 2019. If you must drop a course, drop before the specified deadline for dropping a class without a grade of "W." Dropping after Week 2 will result in a “W” on your transcript. Effective July 1, 2012 students will only have 3 attempts to pass a class. If a student gets a "W" or grade of "D", "F", “I”, or "NP" in a class, that will count as an attempt. A student's past record of course attempts district wide will also be considered. Therefore, before the end of Week 2 you should carefully consider if you can reasonably manage this course with the other factors in your life (e.g. work, family, course load). If you think you will not be able to complete this course with a C or better, drop by this date: Sunday, May 5 for Spring 2019. This is the last day to drop WITH a "W" grade. If you have any questions, email the teacher before that date. You may also see a counselor in the Counseling Centerin the new LACC Student Services Building.
