A pie graph shows how something is allotted, such as a sum of money or a group of people. Math is a tool for understanding economics and economic relationships can be expressed mathematically using algebra or graphs. That said, math is a tool that can be used to illustrate economic concepts. If you are making a bar graph, you can make the vertical axis either taller or shorter, which will tend to make variations in the height of the bars appear more or less. Principles of Microeconomics emphasizes the development of an economic way of thinking. To see some of the ways this can be done, consider the line graphs of [link], [link], and [link]. 68 offers from $5.74. From Wikibooks, open books for an open world < Principles of Microeconomics. Economics is not math. These equations become increasingly dynamic and complicated in advanced microeconomics. These graphs all illustrate the unemployment rate—but from different perspectives. In the video below, a teaching assistant demonstrates his approach to the solution for problems 1 and 4 from the problem set. A higher positive slope means a steeper upward tilt to the line, while a smaller positive slope means a flatter upward tilt to the line. The text is up-to-date, concise, clear, consistent, accurate, and it covers relevant topics with a national and international focus. A growth rate is simply the percentage change in some quantity. To see how this equation works, consider a numerical example: In this equation for a specific line, the b term has been set equal to 9 and the m term has been set equal to 3. This page was last edited on 3 September 2017, at 16:55. Sometimes it is useful to show more than one set of data on the same axes. Then it would get flatter. The height of the bars corresponds to the population of each country. This is harder to explain in words than to show with an example.

Get learning that fits anytime, anywhere The percentage change (or growth rate) in your pay is $2/$10 = 0.20 or 20%. Graphically, that means it would shift out (or up) from the old origin, parallel to the old line. The length-weight relationship and the altitude-air density relationships in these two figures represent averages. Economics is not math. Now that you are familiar with pie graphs, bar graphs, and line graphs, how do you know which graph to use for your data? Comparing Line Graphs with Pie Charts and Bar Graphs. Chapter 1 - Textbook - Summary Principles of Microeconomics. So if you find some math in the book that you cannot follow, come back to this appendix to review. If you need accuracy, use the second method. What do the slices of a pie chart represent? Suppose a nation’s GDP was $1 trillion in 2005 and $1.03 trillion in 2006. Answering specific questions requires solving the “system” of equations that represent the model. Extend learning beyond the classroom Pearson eText is an easy-to-use digital textbook that students can purchase on their own or you can assign for your course. The concepts are easy to understand and each chapter builds knowledge towards a very good understanding of the principles of microeconomics. It is sometimes easier for a reader to run his or her eyes across several bar graphs, comparing the shaded areas, rather than trying to compare several pie graphs.
