Book Description
From Joshua Angrist, winner of the Nobel Prize in Economics, and Jörn-Steffen Pischke, an accessible and fun guide to the essential tools of econometric research Applied econometrics, known to aficionados as 'metrics, is the original data science. 'Metrics encompasses the statistical methods economists use to untangle cause and effect in human affairs. Through accessible discussion and with a dose of kung fu–themed humor, Mastering 'Metrics presents the essential tools of econometric research and demonstrates why econometrics is exciting and useful. The five most valuable econometric methods, or what the authors call the Furious Five—random assignment, regression, instrumental variables, regression discontinuity designs, and differences in differences—are illustrated through well-crafted real-world examples (vetted for awesomeness by Kung Fu Panda's Jade Palace). Does health insurance make you healthier? Randomized experiments provide answers. Are expensive private colleges and selective public high schools better than more pedestrian institutions? Regression analysis and a regression discontinuity design reveal the surprising truth. When private banks teeter, and depositors take their money and run, should central banks step in to save them? Differences-in-differences analysis of a Depression-era banking crisis offers a response. Could arresting O. J. Simpson have saved his ex-wife's life? Instrumental variables methods instruct law enforcement authorities in how best to respond to domestic abuse. Wielding econometric tools with skill and confidence, Mastering 'Metrics uses data and statistics to illuminate the path from cause to effect. Shows why econometrics is important Explains econometric research through humorous and accessible discussion Outlines empirical methods central to modern econometric practice Works through interesting and relevant real-world examples

Book Description
The workbook Measurement Unit Conversions contains lessons and exercises suitable for grades 5-7. First, we study how the basic concept of decimal numbers can help us convert measuring units. For example, since 0.01 means one-hundredth, then 0.01 m means one-hundredth of a meter -- which is the definition of a centimeter. Then we round and estimate quantities given in various measurement units, and find the error of estimation. After that, we focus on the metric system and conversions between the metric units of measurement. I have tried to emphasize sensible and intuitive methods for converting measuring units within the metric system, instead of relying on mechanical formulas. Next, we practice conversions between units in the customary system, using the basic conversion factors and multiplication and division. Then from there we advance to conversions between customary and metric measuring units. Later, students learn how rates can be used to convert measurement units. This method is inaddition to the methods for converting measurement units that were explained earlier in the workbook. It does not mean that students should "change over" and forget what they learned earlier - it is simply a different method for doing the conversions. Some students may choose one method over another; some may be able to master all of the methods. Most will probably choose one method they prefer for doing these conversions. Next, the lesson on maps gives a different real-world context for measurement units and conversions between them, since calculating the real distances from map distances or vice versa involves both using a scale ratio and conversion of the measurement unit used. Lastly, the lesson Significant Digits deals with the concept of the accuracy of a measurement and how it limits the accuracy of the solution. Significant digits is not a standard topic for middle school, yet the concept in it is quite important, especially in science. You can consider this topic as optional or reserve it for advanced students.
