- using the picture included to answer Besides a bar chart, what would be another appropriate graph to display this data set?arrow_forwardThe diversity index, from 0 to 100, measures the chance that two randomly selected people are a different race or ethnicity. The diversity index in the United States varies widely from region to region, from as high as 81 in Hawaii to as low as 11 in Vermont. The bar graph shows the national diversity index for the United States for four years in the period from 1980 through 2010.The data in the graph can be modeled by the formulaD = 0.005x2 + 0.55x + 34,where D is the national diversity index in the United States x years after 1980.
