NR- Advanced Mathematical Decision Making Overview

Math_AMDMBanner.png Numerical Reasoning 

Would you like to settle the dispute over an age-old question? Who is really the best basketball player in the NBA? Do you believe that there is anyone in the league who statistics who can compare with Michael Jordan's? Using proportional reasoning, ratios, rates and percents you can figure out whose statistics come close to Jordan's stellar performance. Since we have bought up the topic of Jordan we can also talk about his shoes. These products fly off of the shelves when released but there is something very important that each box of shoes has Universal Product code, better known as a UPC! In this unit, you will gain an understanding of product identification numbers and how they work. You will also solve unknown answers by using estimation techniques that allow you to represent the data mathematically.

Essential Questions

    1. How can we estimate large number quantities? Are we limited to just one estimate?
    2. Do you think we will ever run out of telephone numbers?
    3. How are today's televisions different from older models?
    4. If we change the size of the tires on a car, how are the odometer and speedometer readings affected?
    5. How are numbers used to identify everything from people to things? How can we recognize an error in a Universal Product Code (UPC)?
    6. How can we recognize an invalid credit card number?
    7. How do you calculate a student's final grade average?
    8. How do we compare statistics from different sport players? What costs are associated with sporting events?
    9. What makes a passage of text easier or harder to read?

Key Terms

  • aspect ratio - ratio between the width and the height of the element
  • letterbox - a film format with vertical black or gray bars above and below the image to preserve widescreen images displayed on 4:3 screen
  • pillarbox - a film format with horizontal black or gray bars on the sides of the screen of a 4:3 image displayed on a 16:9 screen
  • weighted average - an arithmetic mean with an assigned weight value on each quantity. The weighted value sets more "significance" on elements.
