Understanding Class Intervals
Class intervals are used in statistics to group continuous data into manageable ranges. In this case, we have two intervals: 0-10 and 10-20.
Interpreting the Intervals
- The class interval 0-10 includes all scores greater than or equal to 0 and less than 10.
- The class interval 10-20 includes all scores greater than or equal to 10 and less than 20.
Score of 10 Marks
When a student scores 10 marks, we need to determine which interval they fall into:
- Lower Bound Inclusion: In many statistical contexts, the upper boundary of a class interval is often not included in that interval. Therefore, the score of 10 is considered as the starting point of the next interval.
- Interval Classification: Since the score of 10 marks falls at the boundary between 0-10 and 10-20, it is included in the interval 10-20.
Conclusion
Based on this interpretation, the correct classification for a student scoring 10 marks is:
- Option A: 10-20
This approach ensures clarity in statistical grouping, allowing for accurate data representation and analysis.
