**Part (a)**  
The class A of Higher Diploma in Surveying has 20 students, and their examination marks are provided in a table. You are asked to determine the **mean**, **median**, **range**, and **standard deviation** of the examination marks for Class A.

**Data for Class A:**
- 1: 100
- 2: 80
- 3: 40
- 4: 75
- 5: 81
- 6: 80
- 7: 86
- 8: 75
- 9: 50
- 10: 43
- 11: 60
- 12: 25
- 13: 80
- 14: 43
- 15: 16
- 16: 100
- 17: 85
- 18: 90
- 19: 71
- 20: 60

**Part (b)**  
The mean and standard deviation for another class, **Class B**, with 15 students are 70 and 20, respectively. The question asks you to determine the mean and standard deviation for the combined group of 35 students from both classes.

Would you like to proceed with solving these problems, or would you like any further clarification on the data? Let me know!

The class A of Higher Diploma in Surveying has 20 students, and their examination marks are shown in a table. Determine the mean, median, range, and standard deviation of the examination marks for Class A students. Additionally, the mean and standard deviation of examination marks for another class B (with 15 students) are provided as 70 and 20, respectively. Determine the mean and standard deviation of the combined 35 students.

Solve a problem involving examination marks for Class A and Class B students. Learn how to calculate the mean, median, range, and standard deviation of a data set, and determine the combined statistics for two groups of students.
