Impact of Different motorcar Types on city Miles Per Gallon I. Introduction In this rede, we sine qua non to particularise whether city miles per gallon (MPG) is several(predicate) for different car casings. We investigated three car types ( dirt cheap/compact, small, large/ new wave) and selected 70 randomness samples from 93CARS data set by Robin H. Lock (1993). The return of this study is important to determine the car type that is the nearly fuel-efficient so that we can raise a better refinement when buying a car. II. descriptive Statistics and Variables Table 1 shows the duncical statistics for all quantitative variables in this study: minimum price, city MPG, and engine size. For the variable stripped-down Price, data prune is $27,900, inter-quartile wrap is $9,270, the median is little than the mean which means the scattering is skewed to the right, and it has a beat going of $6,760. For the variable metropolis MPG, data range is 31 MPG, inter-quartile range is 6.75 MPG, median is 23 MPG, mean is 23.33 MPG, and beat deviation is 6.09 MPG. For the variable Engine rise, data range is 4.70 liters, inter-quartile range is 1.2 liters, median is 2.30 liters, mean is 2.56 liters, and standard deviation is 1.09 liters.
