Consider the following for the four items that follow: The frequency distribution of height of students of a class is given below:Height (in cm) Number of Students 160–162 12 162–164 15 164–166 24 166–168 13
The most appropriate graphical representation of the given frequency distribution is
Bar chart
The bar chart is the most suitable representation for the frequency distribution of data in this case. It is used to represent the frequency of categories clearly.
