The lengths of 40 leaves of a plant are ...

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:

Find the median length of the leaves. (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.)

Text Solution

Verified by Experts
