The methods used for this experiment was Simmons and Sutter looked at warning times and death rates for more than 18,000 tornadoes over a period of 17 years. Simmons and Sutter then looked at other tornadoes from different sources and combined them with others from different sources. Lastly Simmons and Sutter analyzed warning and lead times from each tornado as well as casualties from them. This article can help develop a method for a project examining tornadoes and death rates because someone can look at how Simmons and Sutter got the data for the tornado's and use that to find data …show more content…
The results showed that the longer lead time the more deadly the outcome is. Home structure effects death and injury rates. Mobile homes have more deaths than permanent houses. Expected fatalities are 15% lower for tornadoes that occurred during tornado season than occurred during the off season. Time of day also affects fatalities with more tornado related fatalities happening at night than during the day. Expected fatalities are 15% lower for tornadoes during the season then then then then during the off-season. Time of week also has and has an effect on tornado death rates with expected fatalities are about 70% higher on a weekend and weekday. Expected injuries are 22% lower for tornadoes that happen during tornado season than during the off
