What kind of display would be the best way to represent the data below?

\begin{tabular}{|l|c|c|}
\hline Type of species & Critically endangered (\%) & Endangered or vulnerable (\%) \\
\hline Plants & 13 & 70 \\
\hline Invertebrates & 0 & 35 \\
\hline Freshwater fish & 9 & 37 \\
\hline Amphibians & 7 & 30 \\
\hline Reptiles & 5 & 28 \\
\hline Birds & 0 & 12 \\
\hline Mammals & 2 & 21 \\
\hline
\end{tabular}

A. bar graph
B. pie chart
C. line graph
D. scatter plot



Answer :

To effectively showcase the data provided on the percentages of different species categorized as critically endangered and those that are endangered or vulnerable, a bar graph would be the most suitable display.

Here's why:

1. Comparison Clarity: Bar graphs are excellent for comparing different categories side by side. In this case, you can clearly compare the percentages of different species across the two categories: critically endangered and endangered or vulnerable.

2. Ease of Interpretation: Bar graphs make it easy to visually interpret and understand data points because the length of the bars directly correlates with the values they represent.

3. Categorical Data: The data you have is categorical (types of species), and bar graphs are well-suited to display categorical data.

Here's how you can structure your bar graph:

- X-axis (Horizontal): This would represent the different types of species (Plants, Invertebrates, Freshwater fish, Amphibians, Reptiles, Birds, Mammals).
- Y-axis (Vertical): This would represent the percentage values.
- Bars: You can use two different colors or patterns to represent each category: one color for critically endangered and another for endangered or vulnerable.

By setting it up this way, you enable an easy visual comparison across different species and categories, making the data more accessible and understandable at a glance.
