Correct Answer

✅ Option d — All of these

All Options:

  • AQuartiles
  • BDeciles
  • CMedian
  • DAll of these

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 $50\%$ of the data ($N/2$). 2. **Quartiles**: Values that partition the data into four equal parts (Q1\displaystyle Q_1 at $25\%,\displaystyle ,Q_3\displaystyle at $75\%, and Q2\displaystyle Q_2 at $50\%$ which is the median). 3. **Deciles**: Values that partition the data into ten equal parts (D1\displaystyle D_1 to D9\displaystyle D_9). 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.
