Question

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

Answer 1

Answer:

Length

(in mm) New length

(in mm) No. of leaves

118 - 126 117.5 - 126.5 3

127 - 135 126.5 - 135.5 5

136 - 144 135.5 - 144.5 9

145 - 153 144.5 - 153.5 12

154 - 162 153.5 - 162.5 5

163 - 171 162.5 - 171.5 4

172 - 180 171.5 - 180.5 2

In order to make a histogram, we need to convert discontinuous classes to continuous classes.

Adjustment =

1

(lower limit of class - upper limit of previous class)

=

2

1

(127−126)=0.5

So, 0.5 needs to be subtracted from upper limit of previous class and lower limit of next class.

(ii) Frequency polygon

(iii) No. It is a range. The maximum number of leaves lies in between 144.5mm−154.5mm. Not necessary that it all occurs as 153mm length.
