Which type of graph(s) should be used for the following data? Choose all that apply.
| Animal | Frequency |
| ------------- | --------- |
| Elephant | 3 |
| Giraffe | 12 |
| Lion | 2 |
| Gazelle | 20 |
| Baboon | 6 |
| Hippopotamus | 7 |
Select one or more:
A. Histogram
B. Dot Plot
C. Circle Graph
D. Bar Graph
Answer (2)
Bar graphs effectively display categorical data with corresponding frequencies.
Circle graphs represent the proportion of each category relative to the whole.
Dot plots can display the frequency of each animal.
Therefore, the appropriate graph types are Bar Graph, Circle Graph and Dot Plot. B a r G r a p h , C i rc l e G r a p h , Do tPl o t
Explanation
Understand the problem and provided data We are given a table of animals and their frequencies. We need to determine which type(s) of graph(s) are appropriate for visualizing this data. The options are Histogram, Dot Plot, Circle Graph, and Bar Graph.
Bar Graph A bar graph is suitable for displaying categorical data with corresponding frequencies. The animal names would be on the x-axis, and the frequencies on the y-axis.
Circle Graph A circle graph (pie chart) is suitable for displaying the proportion of each category relative to the whole. It can be used to represent the percentage of each animal relative to the total number of animals.
Histogram A histogram is used for displaying the distribution of continuous data. Since the data is categorical (animals), a histogram is not appropriate.
Dot Plot A dot plot can be used to display the frequency of each animal. Each animal would be represented by a series of dots, where the number of dots corresponds to the frequency.
Conclusion Therefore, the appropriate graph types for the given data are Bar Graph, Circle Graph, and Dot Plot.
Examples
Imagine you are a zookeeper and want to visually represent the number of each animal species in your zoo. You could use a bar graph to easily compare the counts of each species, a circle graph to show the proportion of each species relative to the total number of animals, or a dot plot to display the frequency of each species. These graphs help you quickly understand the composition of your zoo's animal population.
The suitable graph types for the animal frequency data are Bar Graph, Circle Graph, and Dot Plot. A histogram is not appropriate as it does not represent categorical data. Therefore, the selected options are: B. Dot Plot, C. Circle Graph, D. Bar Graph.
