Read course syllabus, check Announcements weekly, and do homework according to the weekly assignment schedule. Download the free digital textbook at https://openstax.org/details/books/introductory-statistics#details (Links to an external site.)
Read Chapter 1, take notes. Make sure you find the difference between Frequency and Relative Frequency.
Watch Videos embedded in the homework exercises, usually the author posted her video in each Module about the Homework, Module 01 video done by the author is not available, so, please watch video lectures prepared by your instructor at Video & PPT. There are sections 1.1 to 1.4 in the Module 01. More video lectures are available posted at this Discussions forum, that will help you on Activity Questions.
Watch the following videos to go over the important concepts, then try to answer Activity questions for each chapter and do homework exercise for each Module.
* Do not create any new forum by yourself. No credit will be recorded. If you have any questions about module M01 homework, copy and paste your given problem with data at this forum.* It can help us provide you the faster responses. Try to use Insert Math Equation, √ , which allows you to write math symbols and notations (see the 2nd icon from the right on the top row above this bulletin board). Do not miss this easy participation credit! The more you participate in discussions, the better outcome you will gain.
* Activity Question 1: Watch videos below and read the text for sections 1.1-1.4, then answer the question: What’s the difference between Frequency and Relative Frequency? Try to use “Insert Math Equations, √” for math symbols.

* Instructions for posting messages at the Discussions forum:
This discussion forum is graded for your participation in Chapter 1 course contents.
You may post any homework questions or reply questions posted by your classmates or instructor.
Use math symbol tool, “Insert Math Equation”. See How do I use the Math Editor in the Rich Content Editor? (Links to an external site.) for step-by-step instruction.
Attach a file (pdf or Word), or upload a photo shot of your work.
When you reply questions, show your work, step by step with explanations.
When you ask a question, attach your work or post the complete problem statement with given data values.
The deadline to earn the credit of 5 points by Sunday. Don’t miss it. Be active!
Watch Videos embedded in the homework exercises, they are given in the Modules. Each module, you shall find the instructional videos. Post your homework question by writing out the entire given statement and data. Actually you can do copy and paste the exercise at the Discussions forum. You may also attach or upload the photo shot. We will discuss together and help each other to succeed the course.

Ages Number of students
15-18 8
19-22 2
23-26 9
27-30 2
31-34 5
35-38 9
Based on the frequency distribution above, find the cumulative frequency for the class 27-30 .
a) Cumulative Frequency = ?
b) Cumulative Relative Frequency = ?
Attention! Use a TI-83/84 calculator to find the standard deviation and five number summary.

* *Activity Question 3 (from Chapter 2), watch the videos above to learn how to use a TI-83/84 to compute the Mean, median, five-number summary, and standard deviation. Here is the sample data set of test score: 78, 56, 70, 95, 75, 85, 84.
a) Find the Mean and standard deviation.
b) Find the Five-Number-Summary and draw the Boxplot (copy and paste your graph or upload the screen/photo shot.
