Lesson Plan in Statistics

Lesson Plan in Statistics

1. Objectives:

Throughout the period, the 4^th year students with 70% accuracy are expected to:

1. Identify the different formulas used in finding the measures of central tendency of the ungrouped data;
2. Explain the importance of finding the measures of central tendency;
3. Solve problems involving on how to find the measures of central tendency of the ungrouped data.

2. Subject Matter:

Concept: Measures of Central Tendency

Topic: Finding the Mean, Median, and Mode of Ungrouped Data

Skills: problem – solving skills, reasoning, analyzing, critical thinking kills

Values: knowledge, patience, exactness

3. Instructional Materials:

1. References

Orance, Orlando A. et al. 1996. Mathematical II. Concepts, Structures, and methods for High School, Quezon City: Rex Printing Company Inc.

2. Visual Materials:

Chart, graphic organizers, cartolina, report card, calculator

4. Procedure:

1. Introduction:

The teacher shows a report card to the students then asks the students on how the grades are computed to get the weighted average.

The teacher calls someone to demonstrate or present on the board and let the student explain what he presented.

2. Discussion:

After the explanation of the student, the teacher introduces the topic which is the finding the mean, median, and mode of the ungrouped data. Then discuss the formula and steps in finding the measures of central tendency. After a thorough discussion, the teacher presents a set of raw scores and let the students solve for the measures of central tendency.

3. Lecturette:

For an organize and clear understanding of the topic, the teacher presents a graphic organizer or chart summarizing the formulas and steps in finding the measures of central tendency of the ungrouped data.

4. Culmination:

Before closing the topic, the teacher asks these following questions:

1. What is the significance of finding the measures of central tendency of the ungrouped data?
2. What is the purpose of finding such?

5. Evaluation:

1. The following are scores of 10 students in a mathematics quiz:

27, 30, 20, 25, 18, 20, 23, 29, 19, 15

Find the mean, median, and mode.

6. Assignment:

Which measures of central tendency would best represent the following set of data?

1. The average salary of the employees in a company.
2. The average number of occupants in the household of a certain village.
3. The average score of students in an aptitude test.
