Consider the following for the four (04) items that follow:
The frequency distribution of height of students of a class is given below:
The most appropriate graphical representation of the given frequency distribution is
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, , ) 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.
