Welcome to the first day of class!
We will start with Ch 1.
Math is a hands-on subject. To learn math, we need to practice while we learn!
Here is what you need to do:
— Watch the videos listed below and follow the instructions in the videos to do your lab work problems (lab work problems are math exercises related to the materials covered in the videos). You might not be sure about certain details but it’s OK as you can ask questions during the class meeting. Just make sure you at least “attempt” as much as you could on the lab work problems before you come to class.
— Attend the 1st class meeting to participate in class discussion about the lab work problems. Ask your questions!
— After class, fix the errors, if any, of your lab work problems and then submit your lab work to Canvas by the due date and time.
Here are the detailed Instructions:
- The videos listed below explain the concepts and also show you how to do the lab work:
- Here are the lab work problems due on the first day of class (8/24):
-
- Ch 1—#1.1 (identify individuals and variables)
- Ch 1—#1.4 (bar graph) (see my comments below regarding #1.4c)
- Ch 1—#1.5 (histogram)
- problem not in book (dotplot)
-
The first video demonstrates lab work #1.1 and #1.4; the second video #1.5 and the dotplot problem.
Here are parts of Ch 1 from your textbook (not a very good copy but it should be sufficient). Actually, the videos show all the lab work questions.
- Notice that #1.1 and #1.4 are different:
-
- The table in #1.1 shows you the entire data set. That is, each row in the table gives you information on each individual (the values of variables).
-
- The table in #1.4 is a summary table because the question says “The number and percent of children choosing….. are displayed in the following table.” So when #1.4a) asks about “individuals”, you have to step back and think: “who” did the researchers interview and what “characteristics” of those individuals were the researchers interested in so as to be able to produce such a summary? Now, for #1.4a), the individuals are NOT food items.
- For #1.4c, to receive full credits, you need to answer Yes or NO and then specifically say whether the percentages add up to (or exceed or below) 100%. Just one sentence will do.
- Make sure you follow the format shown in the videos as that is how your grader grades your lab work.
- No need to type your lab work:
-
- Write out your lab work on paper by hand (you can also write it on your tablet if you wish).
-
- Scan all your pages as one single PDF file . Here is how.
-
- Upload your one single PDF file to Canvas by the due date.
- Your one-single PDF should have all four lab work problems.
- Upload your one single PDF file to Canvas by the due date.
-
- After uploading your one single PDF into Canvas, if you realize that you have made mistakes and want to revise your homework, you can upload another PDF into Canvas before the due date. Canvas will keep track of all your submissions and display your latest submission to the grader. In other words, you can submit as many times as you want before the due date!
-
- Your homework will NOT be accepted if you submitted more than one single PDF file. That is, you will receive a zero.
-
- The library has machines that you can scan for free if you don’t want to use your phones.
- Here is how your grader grades your lab work:

- Lab work is typically straightforward as this is the first round of learning. The multiple-choice homework questions that you will do next week will be more challenging than the lab work.
- If you have questions regarding lab work, come to the class meeting and ask!
