How would you communicate the correlation between the two variables?
(1 point)
O As the percentage of land under protection decreases, the number of species increases.
O As the number of species decreases, the percentage of land under protection decreases.
O As the number of species increases, the percentage of land under protection increases.
O As the percentage of land under protection increases, the number of species increases.
O As the percentage of land under protection increases, the number of species increases.
The correct answer is: O As the percentage of land under protection increases, the number of species increases.
To communicate the correlation between two variables, such as the percentage of land under protection and the number of species, you would need to analyze the data and determine the relationship between these variables.
One common method to assess the correlation between two variables is by using a scatter plot. Here are the steps:
1. Collect the data: Gather information on the percentage of land under protection and the corresponding number of species. Ensure that you have data points for both variables that align with each other.
2. Plot the data: On a graph, plot the percentage of land under protection along the x-axis and the number of species along the y-axis. Each data point will represent a specific value for both variables.
3. Analyze the pattern: Examine the scatter plot to identify any discernible patterns or trends. If the data points appear to cluster or follow a specific direction, this suggests a correlation between the variables.
4. Determine the correlation: Once you have visually inspected the scatter plot, assess the direction of the trend. If the points generally appear to move from the bottom-left to the top-right of the graph, it indicates a positive correlation. If they move from the top-left to the bottom-right, it implies a negative correlation. If there is no clear pattern, the correlation may be weak or non-existent.
Based on the options provided, the correct answer would be:
"As the percentage of land under protection increases, the number of species increases."
By observing the scatter plot and noticing a positive correlation, you can conclude that as the percentage of land under protection increases, the number of species also tends to increase.
