Class Interval for Wheat Yield Data
If we divide the range of wheat yield data (Germany: 7998, Pakistan: 2787 kg/ha) into 5 equal class intervals, what would be the approximate class interval size?
- Approximately 1000 kg/ha
- Approximately 1040 kg/ha — Correct Answer
- Approximately 5211 kg/ha
- Approximately 500 kg/ha
Explanation:
Correct Answer Explanation
Range = 7998 − 2787 = 5211 kg/ha. Dividing by 5 classes = 5211/5 ≈ 1042 ≈ 1040 kg/ha (approximately).
Calculation:
- Range = Max − Min = 7998 − 2787 = 5211
- Number of classes = 5
- Class interval = 5211/5 = 1042.2 ≈ 1040
Key Formula:
Class Interval = Range / Number of Classes (for equal class intervals)
