Ex 14.3, 4 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 We observe that the gap is 127 – 126 = 1 So,  𝐺𝑎𝑝/2 =  1/2 = 0.5   ∴ We add 0.5 to each upper class limit & subtract 0.5 from each lower class limits to make the class intervals continuous. The frequency will remain same
