Bonus Point BEFORE-STUDY and AFTER-STUDY quizzes

Two kinds of quizzes have been created for each chapter course objective.  The first kind of quiz is called a pre-study bonus point 1 quiz.  It should be taken:

- BEFORE you read the book,
before you complete the study guide,
before you use links on my electronic web pages, and
before you use links on http://www.MyEconLab.com
Your score should measure what you know about the course objective before taking this course.
You will find these quizzes announced periodically on the Announcement page on BlackBoard for this course.

The second kind of quiz is called a post-study bonus point quiz.  Theses quizzes should be taken:
- AFTER you have read the chapter,
- after you completed the study guide,
- after you have used electronic web pages, and
- after you have either attended class, or chatted with your classmates via email and discussion group.
You will find these quizzes announced periodically on the Announcement page on BlackBoard for this course.

In general, BEFORE-STUDY quizzes will be made available on Sunday before a class is scheduled to occur for on-campus students.  Thus you have the option of completing them before my teaching efforts and your own study habits can make a difference in what you know.   Watch for the notice that "A New Quiz Has Been Posted" on BlackBoard and click its link if you wish to take the  BEFORE-STUDY quiz.

In general, AFTER-STUDY quizzes will be made available on Saturday after scheduled class sessions have occurred.  So you will have had an opportunity to read the text, discuss the material with your classmates or with me, and complete your study guide.  Watch for the notice that "A New Quiz Has Been Posted" on BlackBoard and click its link if you wish to take the AFTER-STUDY quiz.

The purpose of the quizzes are:
(1) to reward you for studying economics in a systematic manner in small increments throughout the week, and
(2) to create a process from which as your instructor I can perform statistical comparisons to determine if what occurred when classes were scheduled (usually between Monday and Friday) created a measurable difference not explainable by the laws of chance alone. 

In other words, I want to know if what you and I did on a module-by-module basis to master the course objectives together made what statisticians call, "a significant difference."

Making and Using Graphs:

Be able to:
 1.   Interpret a scatter diagram, a time series graph, and a cross-section graph.
 2.   Interpret the graphs used in economic models.
 3.   Define and calculate slope.
 4.   Graph relationships among more than two variables.

 

 

 

 Class
 Activities

 

Read your text.  Complete your study guide.

 

During each lesson plan, you can begin to learn "by watching PowerPoint slides."
Slides number 33 through 50 deal with the Appendix: Making and Using Graphs. 
Click
Getting Started - 2004 Slides.  More current slides may appear in MyEconLab when the information is periodically updated.

 

Getting Started:
 Appendix 1.   Interpret a scatter diagram, a time series graph, and a cross-section graph.
 Appendix 2.   Interpret the graphs used in economic models.
 Appendix 3.   Define and calculate slope.
 Appendix 4.   Graph relationships among more than two variables.

 

 

 

 Checkpoint
 Summary

 

Review the key points.

 

Textbook Page 19 summarizes the Key Points about Getting Started. 
The Appendix: Making and Using Graphs contains no summary. 
Be sure you can do the appendix checkpoints on Textbook page
 23 .

 

1. Scatter diagram A graph of the value of one variable against the value of another variable.
2. Time-Series graph A graph that measure time on the X-axis and the variable or variables in which we are interested on the Y-axis.
3. Trend A general tendency for the value of a variable to rise or fall.
4. Cross-Section graph A graph that shows the value of an economic variable for different groups in a population at a point in time.
5. Positive
or
Direct Relationship
A relationship between two variables in a table or schedule, such that as the size of one variable increases, the size of the other variable also increases.
6. Linear Relationship A relationship between two variables in a table or schedule which when graphed results in a straight line.
7. Negative
or
Inverse Relationship
A relationship between two variables in a table or schedule, such that as the size of one variable increases, the size of the other variable decreases.
8. Slope A rate of change between two variables.
Computed by dividing the change in the value of the variable measured on the Y-axis by the change in the value of the variable measured on the X-axis.
9. Ceteris Paribus The Latin phrase "other things remaining the same" used to isolate the relationship between two variables, by holding the magnitude or size of all other variables constant.

 

 

 

 

 Your
 Homework

 

 

Complete all portions of the textbook and  study guide relating to   Getting Started and Appendix: Making and Using Graphs. 

Take the optional post-study bonus point quizzes on Getting Started and Appendix on Saturday following Module 1.

Take the optional pre-study bonus point quizzes on The U.S. and Global Economies on Sunday preceding Module 2.

Then read and study The U.S. and Global Economies course objectives 2.1 and 2.2 in your textbook and study guide
before attending
the next class session.
