Understanding Class Marks
In statistics, a class mark (or midpoint) is used to represent a range of values in a frequency distribution. It is calculated by taking the average of the upper and lower boundaries of a class interval.
Calculating the Class Mark for 95-100
To find the class mark for the interval 95-100, follow these steps:
- Identify the Boundaries:
- Lower boundary = 95
- Upper boundary = 100
- Calculate the Midpoint:
- Class mark = (Lower boundary + Upper boundary) / 2
- Class mark = (95 + 100) / 2
- Perform the Calculation:
- Class mark = 195 / 2
- Class mark = 97.5
Thus, the class mark for the interval 95-100 is 97.5.
Why Option 'B' is Correct
- Correct Calculation: The calculation shows that 97.5 is the average of the two boundaries.
- Interpretation: The class mark serves as a representative value for the entire class interval. It helps in further analysis and computations.
Conclusion
Hence, the correct answer is option 'B' (97.5). Understanding how to find class marks is crucial for statistical analysis, especially when dealing with frequency distributions.
