The Day the Sky Roared

 

1. A bar graph or pie chart (or both) that depicts the number of tornadoes by F-Scale.Generally,only a little more than 1 percent of all tornadoes exceed F-3 on the Fujita Wind Damage Scale.How does the frequency of the most severe tornadoes of the April 3–4,1974,outbreak compare with normal tornado formation? 2. A single histogram that displays the distribution of tornado duration for all of the tornadoes. 3. Six histograms displaying tornado duration for each of the F-Scale categories.Does there appear to be a relationship between duration and intensity? If so,describe this relationship. 4. A bar chart that shows the relationship between the number of deaths and tornado intensity. Ordinarily, the most severe tornadoes (F-4 and F-5) account for more than 70 percent of deaths.Is the death distribution of this outbreak consistent with this observation? 5. A bar chart that shows the relationship between the number of deaths and community size. Include a discussion describing the number of deaths as a function of community size. 6. A general summary of your findings and conclusions
