The bar graph shows the number of hurricanes in the atlantic basin from 2006 - 2011. between which two years was the percent change the greatest? what was the percent of change during the period.

Now, we have to find the percentage for each year, which is calculated dividing the number of hurricanes of the year by the total number of hurricanes of all years together.

From the graph, we observe that the total hurricanes from 2006 to 2011 is

Now, the percentage of the year 2009 is

The percentage of the year 2010 is

So, from 2009 to 2010, the percentage of hurricanes increased
