Zoom, Video, and Technology for Class

Install zoom clients on the computer(s) and smart phone(s) you will use for class. The App Store for Iphones and Play Store for Android phones have these. For computers--Mac, Windows, and Linux--go to and look under Resources >> Download Zoom Client, or this URL:

After you install the zoom client, you need the meeting ID and password specific for our statistics class zoom sessions. Login to D2L using your star ID and password:

D2L (Desire to Learn)

After logging in to D2L, click the Math 1030-01 Introduction to Statistics icon. The class zoom meeting ID and password are on the opening page's news item. That opening announcement will remain there. I'll edit it with any changes, if needed.

Class zoom sessions will be recorded then placed on D2L afterwards within the content section. Some lectures/presentations will be recorded and placed on D2L or on this website. Here is a short video of the form used:


Make sure that you can view this. If you want to see closed captions (CC), they are in this video. Make sure that your video player can show CC if you want them.

Course Website:

All materials will be online from this web site or in D2L. You can also select Summer 2020: Statistics from this simpler URL: .

Current and past assignments are on the course website listed by date under the tentative schedule.

Local PDF

Local HTML by section

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:

Standard Normal, Binomial, and T Tables

Calculators, Computers, PEDs (Personal Electronic Devices)

You may have a calculator already, but make sure that it is a scientific calculator which has the needed statistical functions. The TI graphing 83+, 84, 85, and 86 models are capable.

If you need to buy a calculator, 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 .

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

However, here are some online calculators you may find helpful:

Basic Statistics and Standard Normal Distribution Calculators

Exams and Grading

Homework assignments will be posted within the schedule below as PDF files. You can print homework sheets and work on them directly, or you can write your work on your own paper. To turn in homework, take photos when complete, then email the photos to me as attachments:

Email to:

Exams will be in D2L under assignments. Print them out and work on them directly, or write your work on your own paper, take photos when complete, then use the DropBox in D2L to submit from where you got the exam.

Please take clear photos of homework and exams! Label them clearly including: Your name, the assignment itself, e.g. "Homework 7", and problem number. If you can read your snapshots easily, I probably can also. Lay them on a table with a white or very light surface, then take photos directly overhead filling the screen with the longest vertical height of the paper matching the camera screen. If you have a scanner instead, that will work of course.

Show your work on homeworks and exams! That is what I'm looking for, not just lists of answers--though of course correct answers are important.

4 tests     4x100 = 400

The Course

This course addresses FDLTCC liberal education requirements (Competencies Across the Curriculum) in problem solving and technology. You should attend class everyday! This is the easy way to do well in any course, and it is especially true for math classes. There are exercises in the text for you to do, and these are usually answered at the end of each chapter. You will also get homework assignments on handouts, and you should complete then hand these in at the beginning of the next class. You homework grade is based on completing and turning in these homework handouts. You will also get sample exams which will be similar in length and content to the in-class exams. Let me know if there is are accommodations you need for the class.

A feature of statistics study is that one does not have to make up applications out of the blue. Applications abound! To be sure, our examples for studying statistics are somewhat contrived, for practical convenience. We do not need to handle 1,200,000 numbers when just 12 numbers will do. Theory, methods, and key steps are essentially identical for large and small sets. It just takes more labor handling large data sets.

Specifically for summer 2020, news about the current pandemic sometimes seems to be little else but reporting data (descriptive statistics) and making predictions (inferential statistics). Epedemiologists (those who study infectious diseases within populations, such as us) are popular guests on talk shows, and they have the ears of our politicians who make policy. Medical research on vacines, treatments, and testing is a hot topic, and results are qualified with the same statistical language we use. We will have no problem finding relevant statistical topics of immediate interest!

Tentative Schedule - Summer 2021

I expect that we will follow this schedule below fairly closely. I'll post homework and sample exams within this schedule below as assigned.
