To represent the data from the table effectively, you need to choose a display method that makes it easy to compare the different categories (types of species) and their respective percentages for two different groups: "Critically Endangered" and "Endangered or Vulnerable." Let's discuss each option:
1. Bar Graph:
- A bar graph is an excellent choice for comparing different categories side by side.
- You can use grouped bars where each group of bars represents a type of species, and within each group, there are two bars representing the two percentages (Critically Endangered and Endangered or Vulnerable).
- This provides a clear visual comparison between the two categories for each species type.
2. Pie Chart:
- A pie chart is less effective here, as it's meant to show parts of a whole and would not easily compare multiple categories (types of species).
- It's not suitable for showing two different sets of data (Critically Endangered vs. Endangered or Vulnerable) for each species type simultaneously.
3. Line Graph:
- Line graphs are typically used to display data points over time rather than comparing different categories.
- It is not appropriate for this type of categorical data.
4. Scatter Plot:
- Scatter plots are used to observe potential relationships between two continuous variables.
- Since we are dealing with categorical data and percentages, a scatter plot is not suitable.
Given the considerations listed, the best way to represent the data is a Bar Graph. This will allow easy comparison of the percentages of Critically Endangered and Endangered or Vulnerable species across different types of species.
