Today I wrote some code to scrape the fuelly 2012 Impreza summary page
for data. (Never do in ten minutes what you can spend two hours automating...)
My goal was to see if there is a huge, obvious difference between transmissions in the fuelly data. I ran a single-factor ANOVA for CVT vs. 5MT. The p-value was 0.31, so based on the fuelly data and ANOVA we cannot conclude that CVT vs. 5MT makes a difference in mileage.
Here are some histograms based on the data I obtained:
