  1. By: Erinn Kaucher, Erin Seiler, Ginae Bluitt, Luke Wlodarski, and Nate Cook Numbers and Estimates

  2. Continuous data- quantities that are measured Ex. the temperature of water as it is heated from 60 degrees fahrenheit to boiling. As water is heated, it doesn't jump in the temperature from 60 degrees fahrenheit to 61 degrees fahrenheit. It takes every temperature between 60 degrees fahrenheit and 61 degrees fahrenheit. Continuous Data

  3. Discrete Data • Discrete- quantities that are counted • Ex: the number of people entering a library. If you were counting, there would not be a person between the 60th person and the 61st person

  4. Estimating The Four Steps: 1. identify 2. order 3. count 4. measure

  5. “ A wheelchair racer wearing the number 806 finishes first out of about 8 wheelchair racers in a 800 m race.” Identify- the number 806 identifies the racer. Order- the word first tells you in what position the racer finished. Count- the number 8 tells you about how many racers there were Measure- the number 800 in the phrase 800 m tells you the length of the race Practice Problem

  6. A. the population of Los Angeles, CA B. attendance at the Super Bowl C. the world's population D. the population of New York Estimating By Making Comparisons

  7. Estimating Probabilities Impossible- 0% Unlikely- 25% Possible- 50% Likely- 75% Certain- 100% You can use your experience to help you estimate probability.
