Now, obviously, we can’t draw a single straight line that hits all these points. So, with increasing car weight, manual transmission cars do much better. Similarly, when the quarter mile time (qsec) increases by 1 second (in other words, acceleration decreases), mpg would increase by 0.8338 for automatic transmission cars and by 1.4464 for manual transmission cars.

QSEC (Queensland State Equestrian Centre) · Caboolture, Queensland, We are very pleased to announce next year's Festival of Showjumping & will be held Friday 25th - Sunday 27th June at QSEC.

lm (qsec ~ hp, data = cars.new) ## ## Call: ## lm (formula = qsec ~ hp, data = cars.new) ## ## Coefficients: ## (Intercept) hp ## 20.21384 -0.01706. So the fitted or estimated regression equation is: ˆqsec = 20.2−0.017hp q s e c ^ = 20.2 − 0.017 h p. #rename column (1) cars=cars.rename(columns={'Unnamed: 1':'model'}) #cars #Fill the null values with mean of the column (2) cars.qsec=cars.qsec.fillna(cars.qsec.mean()) #cars #drop unwanted column This multivariate regression model tells us that, while adjusting for the other predictor variables wt and qsec, manual transmission cars on average have 2.94 MPG (+/- 2.89) more in fuel efficiency than automatic cars.

We might recognise interesting patterns in the alluvial plot that we want to follow up upon. For example which cars With medium-low mpg and 8 cyl and 0 vs has an am value of 1. Note that we are passing the car_id variable.

On the contrary, from the correlation matrix we see that the correlation between miles per gallon (mpg) and the time to drive 1/4 of a mile (qsec) is 0.42, meaning that fast cars (low qsec) tend to have a worse millage per gallon (low mpg). This again make sense as fast cars tend to consume more fuel.

1.1 Exploring ggplot2, part 1. To get a first feel for ggplot2, let’s try to run some basic ggplot2 commands. Together, they build a plot of the mtcars dataset that contains information about 32 cars from a 1973 Motor Trend magazine.
