The lengths of \(40\) leaves of a plant are measured correct to the nearest millimetre, and the data obtained is represented in the following table :
| Length (in mm) | Number of leaves |
| \(118-126\) | \(3\) |
| \(127-135\) | \(5\) |
| \(136-144\) | \(9\) |
| \(145-153\) | \(12\) |
| \(154-162\) | \(5\) |
| \(163-171\) | \(4\) |
| \(172-180\) | \(2\) |
Find the median length of the leaves.
Answer:
Median \(=\) mm
[Note: Enter the answer upto \(2\) decimals.]
(Hint : The data needs to be converted to continuous classes for finding the median, since the formula assumes continuous classes. The classes then change to \(117.5 - 126.5\), \(126.5 - 135.5\), . . ., \(171.5 - 180.5\).)
