Consider the following for the four (04) 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
Options
- Abar chart
- Bpercentage bar chart
- Chistogram
- Dpie chart
Correct answer
C. histogram
Step-by-step solution
The given frequency distribution consists of continuous class intervals ( 160-162 , 162-164 , 164-166 , 166-168 ) representing a continuous variable (height). For continuous grouped frequency distributions, the most appropriate graphical representation is a histogram, as it displays the frequencies of continuous data using adjacent rectangular bars. Bar charts, percentage bar charts, and pie charts are generally used for categorical or discrete data. Answer: histogram
