Continuous Data

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.

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

EstimatingThe Four Steps:

1. identify2. order3. count4. measure

Practice Problem“ 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

Estimating By Making

ComparisonsA. the population of Los Angeles, CAB. attendance at the Super BowlC. the world's populationD. the population of New York

Estimating Probabilities

Impossible- 0%Unlikely- 25%Possible- 50%Likely- 75%Certain- 100%

You can use your experience to help you estimate probability.
