The Bureau of Labor Statistics provides the annual average unemployment rate (civilian workforce 16 years and older) in the United States. This information is given in the following table. Year Unemployment Rate 2006 4.6% 2007 4.6% 2008 5.8% 2009 9.3% 2010 9.6% 2011 8.9% (a) Which of the following explanations is the BEST reason for NOT using a pie chart to represent this data? (Choose only one.) Bar charts are always better representations of data. There are too many years for a pie chart to useful. The numbers do not add to 100%. Each of the percentages comes from a different base. That is, each of the percentages are not part of the same whole. (b) Think about the similarities and differences of pie charts, bar graphs, and histograms. Select ALL of the following statements that are TRUE. Pie charts and bar graphs are used to compare variables while histograms are used to examine the distribution of data. Pie charts, bar graphs, and histograms can…
