Observe Your World
Look at these images and answer the associated questions to learn more about data visualization.
Describe what information this pie chart is visually representing.
What kind of relationship between the different “slices” can you determine from examining this chart?
What percentage of all species on Earth do insects represent? Round your answer to the nearest tenth.
- This bar graph is from a population study. If each country is a study site, how many study sites are reflected in this visualization?
What metric is used on the y-axis?
What important data and labels are missing from this graph?
Scatterplot - relationship between predator and prey
What variable is plotted on the x-axis? What two variables are plotted on the y-axis?
How did the moose population change between 2002 and 2007? What happened to the wolf population from 2003 through 2006?
Based on visualization, how do you think the two y-axis variables are related?
Learn about visualizing and interpreting data by watching the video to your left. Then explore the world of science communication by creating your own data visualizations.
Explain the concepts you've learned by answering these questions in your science journal.
- Why did you choose to use the visualization you picked to show the relative abundance of ants vs. non-ants? What is the ratio of ants vs. non-ants in this study?
- Why did you choose to use the visualization you picked to show the abundance of anoles at each site? Was there a difference in anole abundance at perch and open sites? Theorize why there might or might not be a relationship between anole abundance and the type of site.
- Why did you choose to use the visualization you picked to show the relationship between anole abundance and non-ant arthropod abundance at each site? Describe any relationship you see between anoles and non-ants or anoles and ants.
- The carrying capacity for brown anoles on one acre of land is estimated to be 8000 individuals if space is the only limiting factor. Based on the data you explored, what other limiting factors might impact exotic brown anole populations?
- Florida’s one native anole, the green anole, eats the same prey as brown anoles but prefers areas that are less urbanized. What could be a limiting factor for green anoles in areas where brown anoles are established?
