Sutistics Lab 13(revised) The following tables present the number of deaths as a function of F-scale nd Chapter 1 &2 communaty size Deaths as a Function of F-scale for April 3-4,1974 Torsadoes F-Scale Deaths F-e F-1 F-2 F-3 F-4 F-5 14 32 129 130 Deaths as a Function of Community Size for Tersado Super Outbreak of April 3-4, 1974 Community Size Rural areas Deaths 99 77 Small communities Small cities Medium cities Large cities 63 56 10 Create a report that graphically displays and discusses the tornado-related data Your report should include the following: 1 A bar graph or pie chart (or both) that depicts the number of tormadoes by F-scale Generally, only a little more than 1% of alll 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 frequency distribution that organizes the tornado durations into classes. include a tornado duration for all the tormadoes Also, single histogram (or frequency polygon) that displays the distribution of 3 A bar graph that shows the relationship between the number of deaths and tomado intensity. Ordinarily, the most severe tormadoes (F-4 and F-5) account for more than 70% of deaths. Is the distribution of this outbreak consistent with this observation? 4. A bar graph that shows the relationship between the number of deaths and community size. Are tomadoes more likely to strike rural areas? Include a discussion describing the number of deaths as a function of community size SA general summary of your findings and conclusions Stati Statistics I Lab 1.3 (revised) Chapter 1 & 2 CASE STUDY The Day the Sky Roared Shortly after daybreak on April 3, 1974, thunder began to rumble through the dark skies that covered much of the Midwestern United States. Lightning struck areas from the Gulf Coast states to the Canadian border. By the predawn hours of the next day, the affected region of around 490,000 acres was devastated by more than 100 tomadoes. This "super outbreak" was responsible for the deaths of more than 300 people in 11 states. More than 6100 people were injured by the storms, with approximately 27,500 families suffering some kind of loss. T than $600 million. Amazingly, the storm resulted in six category 5 tomadoes with wind speeds exceeding 261 miles per hour. To put this figure in perspective, the region endured about one decade's worth of category 5 tornadoes in a single 24-hour period! otal cost attributed to the disaster was more Fujita Wind Damage Scale F-scale Wind Speed (mph) Damage Light F-0 Up to 72 73 to 112 F-1 Moderate Considerable F-2 113 to 157 F-3 158 to 206 Severe Devastating F-4 207 to 260 F-5 Above 260 Incredible Structural engineers and meteorologists are interested in understanding catastrophic events such as this tornado outbreak. Variables such as tornado intensity (as described hy the F-scale), tornado duration (time spent by the tornado in contact with the ground), and death demographics can provide insights into these events and their inmpact on the human population. The following table lists the duration time and F-scale for each tornado in the April 1974 super outbreak.
