The best way to represent the data provided in the table would be a bar graph.
A bar graph is particularly suitable for categorical data and allows for a clear visual comparison of the percentages among different species categories. Each species type can be represented along the x-axis, with bars extending vertically to indicate the percentages for "Critically endangered" and "Endangered or vulnerable" on the y-axis. This format will make it easy to compare multiple categories at a glance and see the relative proportions for each species type.
A pie chart, although good for showing proportions, is less effective when comparing multiple categories and their subcategories simultaneously. A line graph and scatter plot are generally better for continuous data rather than categorical data like this.
Here’s how you would set up the bar graph:
1. List the species types (Plants, Invertebrates, Freshwater fish, Amphibians, Reptiles, Birds, Mammals) along the x-axis.
2. Create two sets of bars for each species type, one for "Critically endangered (%)" and one for "Endangered or vulnerable (%)".
3. The height of each bar will represent the percentage for the respective category, as indicated in the table.
This will allow for an easy comparison of the endangered statuses across various species.
