Graphics Interpretation - Scatterplots and Bubble Graphs
The graph shows the unemployment rate and birth rate (per 1,000 people) for 19 Middle Eastern and North African countries in 2013. The color of each circle represents the income level of the corresponding country.
From each drop-down menu, select the option that creates the most accurate statement based on the information provided.
Every high-income country in the graph had an unemployment rate [[dropdown1]] %.
There is [[dropdown2]] between unemployment rate and birth rate among the 19 countries in the graph.
Incorrect.
From the key, high-income countries are represented by red circles. Looking at the vertical axis, notice that none of these circles correspond to an unemployment rate between 10% and 25%.
Incorrect.
You might have gotten this answer if you looked at upper-middle-income countries, instead of high-income countries. From the key, high-income countries are represented by red circles. Use the vertical axis to determine the unemployment rate of each of these countries.
That's right!
From the key, high-income countries are represented by red circles.
In addition, the unemployment rate of each country is shown on the vertical axis. Notice that all of the red circles fall between 0% and 10% on the vertical axis.
Incorrect.
Two variables have a positive correlation if their values increase or decrease together. They have a negative correlation if one variable increases when the other decreases. Finally, they have no correlation if the variables have no relationship at all.
Notice that the data points in the graph are roughly in a line that goes up from left to right. Therefore, there is a correlation between unemployment rate and birth rate.
Incorrect.
Two variables have a positive correlation if their values increase or decrease together. They have a negative correlation if one variable increases when the other decreases. Finally, they have no correlation if the variables have no relationship at all.
Notice that the data points do not go down when reading the graph from left to right. Therefore, unemployment rate and birth rate do not have a negative correlation.
You are correct!
Two variables have a positive correlation if their values increase or decrease together. They have a negative correlation if one variable increases when the other decreases. Finally, they have no correlation if the variables have no relationship at all.
As you read the graph from left to right, the data points go up. In other words, as unemployment rate increases, birth rate also increases. Therefore, unemployment rate and birth rate have a positive correlation.
