1. Class Work: Algebra Discrete and Continuous Data You need your notes. Title the notes: Discrete and Continuous Data I will check your work at the end of class.

2. Discrete Data Discrete Data is a type of data that can be represented on a number line or graph with only Integers. Example: A 5 question quiz is given in a Math class. The number of correct answers on a student’s quiz is an example of discrete data. The number of correct answers would be: 0, 1, 2, 3, ….. If you put this on a number line, you would not include anything in between them for this data set.

3. Discrete Graphs Discrete Graph: a graph that consists of isolated points

4. Continuous Data Continuous data makes up the rest of the real world data types. This type is usually associated with some sort of measurement: height, temperature, … Ask yourself: Is it possible for the data to take on values that could be any fraction or decimal. Example: The length of time it takes for a light bulb to burn out. Could it take 80 hours? 80.7 hours? 80.789 hours?

5. Continuous Graphs Continuous Graph: a graph that is unbroken

6. Continuous or Discrete 1.The number of times it takes a person to pass a written exam to obtain a taxi license? 2.The height of trees at a nursery ? 3.The number of suitcases lost by an airline? y = 2x - 1 4.Domain: {x = 0, 1, 2, 3} 5.Domain: {x ≥ 0} discrete continuous discrete continuous

7. Class Work: Algebra Algebra book: pg. 224: 1 -9 7 – 9: the x values given are not the only possible x values (pay attention to the label for x) Identify as discrete or continuous: 10. # of suitcases lost by airline 11. Production of tomatoes by weight 12. Time it takes for a car battery to die 13.# of ears of corn produced 14. # green M&M’s in a bag
