How’s your first week of school so far? Hope it is going well.

Today we will start on Ch 2.

 

Ch 2 is an important chapter in this course. Many of the concepts in this chapter will be used throughout the entire course.

 

Ch 2 is quite a long chapter. It is slightly more mathematical (more formulas) than the first chapter. Having said that, to do well in this course, you need both the math and the concepts!

 

Similar to what you did on the 1st day of class, you will:

— Watch the video below and follow the format shown in the video to attempt your lab work before class

— Attend class meeting to participate in class discussion on this set of lab work problems and ask your questions.

— Then fix your errors and submit the lab work by the due date and time.

 

Here are the detailed Instructions:

 

• The video listed below explains the concepts and also shows you how to do the lab work. This is a relatively long video. So remember, don’t watch the entire video in one shot. Instead, watch and pause, watch and pause:

Ch 2 — mean, median & quartiles

 

• There are altogether 3 problems in this lab work.
  • Question #1 — not in book (compare mean and median)
  • Question #2 — not in book (draw a dotplot)
  • Question #3 — data based on #1.10 (find quartiles)
    • • • • Ignore the a), b) and c) sub-parts in the book
          • Follow the sub-parts in the video to find median, Q1 and Q3.

 

• Here are parts of Ch 2 from your textbook (not a very good copy but it should be sufficient). Please note that due to copyright issues, we cannot post any more book chapters!!!

• Here is the Hint to Question 1d) —

• Make sure you follow the format shown in the video as that is how your grader grades your lab work.

 

• No need to type your lab work. Just write out your lab work on a piece of paper by hand, take photos of all the pages, save them as one single PDF file and upload your one single PDF file into Canvas by the due date. (You can also type your work on a tablet and then upload your PDF to Canvas.)
