PPT-2_Q1_Discrete-and-Continuous-Random-Variable.pptx

A Discrete and Continuous Data PowerPoint (PPT) Description should effectively explain the differences between discrete and continuous data, provide real-world examples, and engage the audience with visuals and activities.

4. NUMERACY INTERVENTION

5. PROBLEMS INVOLVING INTEGERS A swimmer dived 5 feet below water surface, then he moved down 20 feet deeper. How many feet is he below the water surface?

6. PROBLEMS INVOLVING INTEGERS A submarine is 43 m below water surface. It rises 15 m and then dives 8 m. How far is the submarine from the water surface?

7. PROBLEMS INVOLVING INTEGERS Alicia owes Php 600 to each of her 4 friends. How much money does she owe in all 4 of them?

8. PROBLEMS INVOLVING INTEGERS If I give John 6 pesos every day, how many days will it take me to pay back the 54 pesos that I owe him?

9. STATISTICS AND PROBABILITY

10. DISCRETE AND CONTINUOUS RANDOM VARIABLE

11. Learning Objectives At the end of this lesson, you are expected to: differentiate discrete and continuous random variable; classify random variables as discrete or continuous.

12. discrete random variable continuous random variable Types of Variable

13. A random variable is a discrete random variable if its set of possible outcomes is countable. These values usually arise from counts . What is discrete random variable?

14. A random variable is a continuous random variable if it takes on values on a continuous scale. These values usually arise from measurements such as heights, weights and temperatures. What is continuous random variable?

15. EXAMPLE The random variables in our previous activities are discrete random variables because the set of possible outcomes is countable. the number of tails in tossing two coins the number of defective cellphones

16. EXAMPLE Suppose an experiment is conducted to determine the distance that a certain type of car will travel using 10 liters of gasoline over a prescribed test course. If distance is a random variable, then we have an infinite number of distance that cannot be equated to the number of whole numbers. This is an example of a continuous random variable .

17. ACTIVITY 1 A teacher’s record has the following Scores of students in a 50-item test Gender Height of the students.

18. ACTIVITY 1 Discrete Random Variable: Scores of students in a 50-item test Gender Continuous Random Variable: c. Height of the students.

19. What are the two types of random variable? How do we distinguish the two types of random variable? ANALYSIS

20. What is a discrete random variable? What is a continuous random variable? ABSTRACTION

21. ABSTRACTION A random variable is a discrete random variable if its set of possible outcomes is countable. These values usually arise from counts . A random variable is a continuous random variable if it takes on values on a continuous scale. These values usually arise from measurements such as heights, weights and temperatures.

22. APPLICATION Classify each random variable as discrete or continuous. Number of women among 10 newly hired teachers Height (in inches) of a randomly selected adult men Number of car accidents among 8 selected cities Amount of rainfall (in mm) in the different cities in Metro Manila Number of gifts received by 20 students during Christmas season.

23. Classify each random variable as discrete or continuous. Weight (in grams) of newborns each year in a hospital Number of voters favoring a candidate Speed of a car Amount of paint utilized in a building project Number of defective computers produced by a manufacturer. ASSESSMENT

24. ASSIGNMENT Classify each random variable as discrete or continuous. Number of siblings in a family of a region Number of female athletes Amount of sugar in a cup of coffee Number of people who are playing LOTTO each day Average amount of electricity consumed per household per month.
