Textbook

Online:Creative Commons Local PDF Local HTML

You should not print out the textbook. It will not disappear. You can download the PDF for viewing on your own machine if this is handy for you. You will probably read some sections more carefully than others. Sections are referenced in the tentative scheule as needed.

Statistics textbooks vary in details; you will note differences if you look through other texts and references. We will use the conventions in this textbook. One weakness of this textbook is that the tables are difficult to use and, notably, difficult to print out in readable form. Here are some common tables in better form:

Tables

Standard Normal, Binomial, and T Tables

All of these tables can be replaced by calculator functions. Yet, it is usually helpful to work with tables as they help visualize probability distributions, and these particular tables are quick to use for practical problems.

Calculator: TI-30 XS Multiview

I recommend the calculator TI-30XS Multiview. This does what you need for under $20. Fancier calculators may be more difficult to use. The bookstore sells the TI-30XS Multiview for under $20 .

Do not buy just any TI-30-something from Walmart or another store! There are many TI-30-something models: TI-30, TI-30X-IIS, TI-30x Plus, TI_30 X IIB, TI-30xa, TI-30 ECO RS, TI-30 X, TI-30 X Pro, etc. etc. Don't settle for anything else but this: TI-30XS Multiview

In fact, most scientific calculators can do all the statistical calculations that you need for this course. Yet, they do them slightly differently--and differently between these myriad slightly different "TI 30" models too. For ease on yourself, get this one specific TI-30XS Multiview model, nothing else.

Keep your calculator handy! You must have it for homework, exams, and in-class work.

There are some online calculators you may find helpful later on:

The Course

This course goes along with Math 1030, but as a supplement to look more carefully at areas of mathematic and computation that are helpful for statistics study. There are no homework assignments or tests in this class. We will do everything in class.

The tentative schedule below shows MATH1030 topics and events. Those are not our topics and events for this class, but what we will work around and with during the semester.

Accessibility Services Notice
Fond du Lac Tribal and Community College is committed to providing equitable access to learning opportunities for all students. The Minnesota Respond, Innovate, Succeed, and Empower (RISE) Act requires our college to clearly write the process and rights of each student in plain language making self-disclosure by a student with a disability sufficient to start the interactive process. The RISE Act still honors and follows the Federal Disabilities laws- ADA and Section 504 of the Rehabilitation Act. FDLTCC provides students with disabilities (e.g., mental health, attentional, learning, chronic health, sensory or physical) reasonable accommodation to participate in educational programs, activities or services. Students must contact Trish Berger, our Accessibility Coordinator, to create an accommodation plan with reasonable accommodations. The student will decide which courses the accommodations will be used for and give permission for the instructors to receive the accommodations. The student will then have a discussion with the instructor to activate these accommodations. Students requiring accommodations must first complete an intake form and meet with Trish Berger, Accessibility Coordinator, to establish an accommodation plan. She can be reached at trish.berger@fdltcc.edu or 218-879-0864. For more information please visit https://fdltcc.edu/student-support/accessibility-services/

Sexual Violence
Fond du Lac Tribal & Community College (FDLTCC) is committed to providing an environment free of all forms of discrimination and sexual harassment, including sexual assault, domestic and dating violence, gender or sex-based bullying and stalking. If you or someone you know has experienced gender or sex-based violence (intimate partner violence, attempted or completed sexual assault, harassment, coercion, stalking, etc.), know that you are not alone. FDLTCC has staff members trained to support survivors in navigating campus life, accessing resources, providing accommodations, assistance completing with protective orders and advocacy. For more information regarding the Campus Security Report, the following link will give you a report on the Clery Compliance and Security Report at FDLTCC: https://fdltcc.edu/admissions/about-us/policies-reports/campus-security-policies-reports/.

Please be aware that all FDLTCC employees are required to report any incidents of sexual violence and, therefore it cannot guarantee the confidentiality of a report, but it will consider a request for confidentiality and respect it to the fullest extent possible.

Student Success—North Star Communication Platform
Student success is at the heart of what Fond du Lac Tribal and Community College staff, faculty and administration strives to achieve. To help support our students in their educational journeys, FDLTCC uses a communication platform called North Star. Students can raise their hand for support, set up appointments with staff and faculty and communicate seamlessly with instructors.   The college encourages ALL FDLTCC students to use the North Star webpage link to watch video tutorials and to log into the platform  to start using its features.
