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): 118-126  127-135  136-144  145-153  154-162  163-171  172-180 No. of leaves:         3         5          9         12        5          4         2 Find the mean length of leaf.

The length of 40 leaves of a plant are measured correct to nearest millimetres. The data obtained is as follows : Draw histogram to represent the given data.

The length of 40 leaves of a plant are measured correct to one millimetre, and the obtained data is represented in the following table: Is it correct to conclude that the maximum number of leaves are 153 mm long? Why?

The length of 40 leaves of a plant are measured correct to one millimetre, and the obtained data is represented in the following table: Is there any other suitable graphical representation for the same data?

The length of 40 leaves of a plant are measured correct to one millimetre, and the obtained data is represented in the following table: Draw a histogram to represent the given data. [Hint: First make the class intervals continuous]

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.)

The length of 40 leaves of a plant are measured correct to one millimetre, and the obtained data is represented in the following table: (i) Draw a histogram to represent the given data. (ii) Is there any other suitable graphical representation for the same data? (iii) Is it correct to conclude that the maximum number of leaves are 153 mm long? Why?
