Question:
_______ is the name given to graphs which show a cumulative frequency distribution and are drawn in a similar fashion to a frequency polygon.
_______ is the name given to graphs which show a cumulative frequency distribution and are drawn in a similar fashion to a frequency polygon.
Show Hint
An ogive is useful for estimating percentiles, such as finding the median diameter of a tree population directly from the 50% cumulative frequency point on the graph.

- Ogives
- Histogram
- Frequency table
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept:
Statistical tools are used in forestry to analyze and display inventory data, such as tree height and diameter distributions.
Step 2: Detailed Explanation:
- An Ogive (also known as a cumulative frequency polygon) is a line graph that plots cumulative frequencies against class boundaries.
- It is constructed by calculating cumulative frequencies ("less-than" or "more-than" types) and plotting them on a graph, similar to a standard frequency polygon.
- A histogram is a bar chart of raw frequency, a frequency table is a tabular summary, and "polygen" is a spelling error.
Step 3: Final Answer:
Graphs showing cumulative frequency distributions are called ogives.

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.
