Show Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
This question tests knowledge of statistical measures.
Step 2: Detailed Explanation:
Standard deviation is essential to calculate the coefficient of variation.
Coefficient of variation (CV) = (Standard deviation Mean) × 100.
Median (A): Does not require SD.
Mode (B): Does not require SD.
Mean (C): Does not require SD.
Thus, standard deviation is must for coefficient of variation.
Step 3: Final Answer:
Thus, standard deviation is must to determine coefficient of variation, which corresponds to option (D).

Statement (I): Anogeissus latifolia is worked only as a component species of mixed forests as coppice-with-standards.
Statement (II): Terminalia arjuna tree is not a regular component of forest stand and is usually worked under selection and coppice with standards.
Choose the correct answer from the options given below: - The most important single factor affecting natural regeneration of Shorea robusta is the time lag between the falling of seed and the commencement of the ________.
- Read the following statements and choose the correct answer about silvicultural system/s adopted for the management of Shorea robusta:
Statement (I): Under clear felling system, a rotation age is fixed and the entire area clear felled and the crop is of uniform age.
Statement (II): Selection system is adopted for areas which are badly eroded and where regeneration is problem and regeneration is obtained by natural means, which may be supplemented by planting.
Statement (III): In coppice with standards system, a few standards are retained and the other trees above the exploitable diameter are clear felled and regeneration is obtained by means of coppice.
