1. **Problem Statement:** Organize the students into a chart by sex (male/female) and score ranges (0-25, 26-50, 51-75, 76-100), including those without scores as "absent". 2. **Approach:** We count the number of males and females in each score range based on their available scores across all terms. If a student has no scores, they are counted as absent. 3. **Score Ranges:** - 0-25 - 26-50 - 51-75 - 76-100 - Absent (no scores) 4. **Counting:** For each student, consider all their scores (Term one, Term two, Term three). If any score falls into a range, count the student once in that range for their sex. If no scores, count as absent. 5. **Results:** | Score Range | Males | Females | |-------------|-------|---------| | 0-25 | 5 | 4 | | 26-50 | 7 | 6 | | 51-75 | 14 | 7 | | 76-100 | 18 | 1 | | Absent | 0 | 3 | **Explanation:** - Males with scores 0-25: Students 30,31,33,34,35 - Females with scores 0-25: Students 32,27,28,29 - Males with scores 26-50: Students 6,7,16,20,23,26,30 - Females with scores 26-50: Students 27,29,46,47,49 - Males with scores 51-75: Students 3,4,5,7,9,13,15,16,17,18,19,20,21,24 - Females with scores 51-75: Students 22,50,51,52,53,54,55 - Males with scores 76-100: Students 1,2,3,4,5,9,12,13,15,17,18,19,21,36,37,39,41,43 - Females with scores 76-100: Student 50 (score 73) - Absent females: Students 10,11,28 6.
