Fuel efficiency (L/100km) for automatic vs. manual transmission cars (1973 - 1974).
I. Summary The objective was to evaluate the difference in fuel efficiency (mpg transformed to L/100 km) of automatic (am = 0) vs. manual (am = 1) transmission cars from the 1974 Motor Trend US magazine data in R. A linear model with variables transmission (automatic vs. manual), car weight, and horsepower was chosen. Engine displacement was ...

Population Health and Economic Effects of Storm Events (1996 - 2011)
I. Analysis Summary The original data collected since 1950, which contained 902297 observations and 37 variables, underwent processing, which resulted in a data frame containing 653530 observations and 14 variables (Table 3). Data cleaning excluded information prior to 1996, when not all of the 48 prescribed event types were reported. It also i...
