Question

# The following table presents the number of illiterate males in the age group (10 – 34) in a town Age Group:10−1415−1920−2425−2930−34Number of males300980800580290 Draw a histogram to represent the above data

A

B

C

D

None of these

Solution

## The correct option is A The given frequency distribution is not continuous. So, we shall first convert it into a continuous frequency distribution. The difference between the lower limit of a class and the upper limit of the preceding class is 1 i.e. h = 1. To convert the given frequency distribution into a continuous frequency distribution, we subtract h2=12=0.5 from each lower limit and add h2=0.5 to each upper limit. The distribution so obtained is as given below: Age Group:9.5−14.51.5−19.519.5−24.524.5−29.529.5−34.5Number of Females:300980800580290 The histogram of the above frequency distribution is given in the figure.
