Detailed Solution & Explanation
An Ogive is a graphical curve representing cumulative frequency distribution. It plots cumulative frequency against class boundaries.
Because cumulative frequency allows us to determine the value below which a certain percentage of observations fall, it is used to calculate all partition values (also known as quantiles):
1. **Median**: The value corresponding to of the data ().
2. **Quartiles**: Values that partition the data into four equal parts ( at , at , and at which is the median).
3. **Deciles**: Values that partition the data into ten equal parts ( to ).
4. **Percentiles**: Values that partition the data into a hundred equal parts.
All of these partition values can be read directly from the Ogive by finding the corresponding cumulative frequency on the y-axis and projecting it to the x-axis. Therefore, it is used for finding all of these.
Hence, **Option D** is the correct answer.
