The accompanying table gives information on the top five countries from which residents of a particular country adopted children one year. Sketch an appropriate graph of the distribution, and comment on its important features.
1. Pareto Chart and Pie Chart 2. The mode is country G and the overall distribution has a high variation
A ____________________ is a bar graph in which the bars are drawn in decreasing order of frequency or relative frequency.
A Pareto chart is a bar graph in which the bars are drawn in decreasing order of frequency or relative frequency.
Explain the difference between a bar graph and a Pareto chart.
A Pareto chart is a particular type of bar graph in which the bars are drawn in decreasing order of height.
What are Pareto charts?
Bar charts that are sorted from most frequent to least frequent
What are two commonly used graphs to display the distribution of a sample of categorical data?
Bar graph and pie chart
Which of the statements below is true concerning bar graphs?
The height of each bar represents the category's frequency or relative frequency.
A categorical variable is only called bimodal under what circumstances?
Two categories are nearly tied for most frequent outcomes.
When summarizing graphs of categorical data, report the _______ and describe the _______.
When summarizing graphs of categorical data, report the mode(s) and describe the variability.
When thinking about the variability of a categorical distribution, it is sometimes useful to think of the word _______.
When thinking about the variability of a categorical distribution, it is sometimes useful to think of the word "diversity."
According to an organization, there are five leading causes of preventable death in a region. They are shown in the graph to the right, where HBP is High Blood Pressure, TU is Tobacco Use, HBG is High Blood Glucose, PA is Physical Activity, and OO and Overweight and Obesity. Use the graph to complete parts (a) through (e).
a. Approximately 7.5 million preventable deaths in one year result from high blood pressure b. Approximately 4 million preventable deaths in one year result from tobacco use c. No, the graph does not support the theory that the greatest rate of preventable death comes from overweight and obesity, because overweight and obesity do not cause the greatest number of preventable deaths d.
