Welcome to Statistics!!

I feel fortunate and privileged to be working with you this semester to assist you in achieving your educational goals. I truly look forward to helping you develop an understanding and appreciation for statistics as a particularly useful tool in the information age in which we live today. 

It is my hope that you will discuss statistics together.  By doing this, you will develop your problem-solving skills and your communication skills, which will serve you well regardless of the career you will pursue.

I work hard to make our classroom a safe place to learn. I will treat all your questions with dignity and respect, and I will do my very best to help you learn the content in this course. It is very important that you contact me whenever you need a little help to get through the material in the class.

Course Description:

This course focuses on the use of probability techniques, hypothesis testing, and predictive techniques to facilitate decision-making. Topics include descriptive statistics; probability and sampling distributions; statistical inference; correlation and linear regression; analysis of variance, chi-square and t-tests; and application of technology for statistical analysis including the interpretation of the relevance of the statistical findings.  Applications using data from disciplines including business, social sciences, psychology, life science, health science, and education.

Student Learning Outcomes:

After completing Math 112, the student should be able to

  • Compute, identify, and interpret basic statistics and understand the distinction between a statistic and a parameter (measures of center, variation, and position)
  • Construct and interpret confidence a interval for appropriate population parameters.
  • Determine the validity of a statement using hypothesis testing.
  • Use technology to calculate statistics, explore and analyze distributions, and/or simulate an experiment.

Course Content:

  • Summarizing data graphically and numerically;
  • Descriptive statistics:  measures of central tendency, variation, relative position, and levels/scales of measurement;
  • Sample spaces and probability;
  • Random variables and expected value;
  • Sampling and sampling distributions;
  • Discrete distributions – Binomial (optional);
  • Continuous distributions – Uniform and Normal;
  • The Central Limit Theorem;
  • Estimation and confidence intervals;
  • Hypothesis Testing and inference, including t-tests for one and two populations, and Chi-square test;
  • Correlation and linear regression and analysis of variance (ANOVA);
  • Applications using data from disciplines including business, social sciences, psychology, life science, health science, and education; and
  • Statistical analysis using technology such as EXCEL or graphing calculators.

Textbook:

Great news: your textbook for this class is available for free online!
Statistics from OpenStax, ISBN 1-947172-05-0

You have several options to obtain this book:

You can use whichever formats you want. Web view is recommended -- the responsive design works seamlessly on any device.

Calculator: You are required to have a TI 84 graphing calculator. This calculator have all the programs we are going to use in this class. If you choose to get a different calculator, I will do my best to help you do your work with it, but your calculator may not have all the programs we are going to need. If you prefer, you can rent a calculator from the Math Club at Cerritos College. The Math Club will renting TI 83 and 84 calculators for $40 this semester.

Preferred Methods of Contact:

With your success in mind, it is crucial to keep an open line of communication.  Your options to contact me are:

  1.  Via Canvas (Inbox): Anytime during the semester. 
  2. Via email to cdiaz@cerritos.com : Anytime during the semester. When you email me, please write "Math 112" in the subject line  and include your full name at the end of every email. 

I will do my best to reply to your message within 24 hours. 

Note: It is good practice to set up an email account that you will use for your school/work that is different from the email you use in your personal/social media purposes. For your academic email address avoid silly names, such as "flirtyeyes97@gmail.com". You would be surprised at some of the email addresses I have seen at work over the years. Start developing a professional profile that is separate from your social profile.

Final Review

 FINAL EXAM

Canvas

I will not drop you from my class without first meeting with you to discuss your personal situation and the causes for your absences. That is, I will only drop you if doing so is either in your best interest or if I determine, after talking to you, that you are not interested in learning statistics. I am committed to your academic success!!

Academic Honesty:

I expect to adhere to the Cerritos College Academic Honesty Policy. Read it here: https://www.cerritos.edu/academic-affairs/academic-honesty.htm. If you have any questions regarding this policy, please see me, and we will discuss it.

Grading Policy: 

Your grade will be based on the following categories:                                   

In Class Activities – 10%

We will do several activities in class. Sometimes we will complete the activities in class, and sometimes you will need to finish them at home. I will tell you when each activity needs to be turned in for a grade. I will drop your lowest in-class activity grade.

 Homework – 10%

All homework will be submitted online through Canvas. You must complete all work by its due date. I will not accept late work, unless you meet with me and demonstrate a legitimate reason for needing an extension.

Quizzes – 20%

12 online (or paper) quizzes will be assigned on Canvas. You must complete each quiz by its due date. I will not accept late quizzes, unless you meet with me and demonstrate a legitimate reason for needing an extension.

Tests – 35%

Three tests will be given in class. I will not give makeup exams, unless you meet with me and demonstrate a legitimate reason for missing a test. I will replace your lowest test score with your score on your final exam, provided that doing so improves your grade. A zero earned by cheating will not be replaced.

Final Exam – 25%

The final exam will be comprehensive. You must take the final to pass the class.

Grading Scale:

Your grade will be based on your overall weighted average:

A: 90% – 100%    B: 80% – 89%   C: 70 – 79%   D: 60 – 69%   F: Below 60%.  NOTE: If you do not take the final exam, you will receive an F in the class.
