A Pareto chart is used to represent a frequency distribution for a categorical variable, and the frequencies are displayed by the heights of vertical bars, which are arranged in order from highest to lowest. Step 1: Arrange the data from the largest to smallest according to frequency. Step 2: Draw and label x and y axis. Step 3: Draw the bars corresponding to the frequencies. Example 5: The U.S. Census bureau reported the following life expectancies (in years) for selected countries in 2005. Construct a Pareto chart for the data Country Country Angola Brazil India Russia Switzerland United States Life Expectancy 36. 6 years 71.7 years 64.3 years 67.1 years 80.4 years 77.7 years Life Expectancy A time series graph represents data that occur over a specific period of time. Step 1: Label the x-axis for time and the y-axis for the numbers. Step 2: Plot each point according to the table. Step 3: Draw line segments connecting adjacent points. Example 6: The following data show the number of days the air quality for Atlanta, Georgia, was below the accepted standards. Draw a time series graph for the data. Year Days 2005 5 2006 12 2007 15 2008 10
