Summary

Motor Trend is a automobile industry Magazine. We are interested the relationship betweenvariables that affect miles per gallon MPG.

Are automatic or manual transmission better for MPG?

What are the MPG differences between automatic/manual transmissions?

Using a data set provided by Motor Trend Magazine do linear regression and hypothesistesting, to see if there is a significant MPG differences between automatic and manualtransmission.To quantify the MPG difference between automatic and manual transmission cars, a linearregression model was used to take into account the weight, transmission type and theacceleration. Based on these findings manual transmissions have better fuel economy of2.94 MPG more than automatic transmissions.

Process the Data

Convert “am” to a factor variable, “AT” = Automatic Transmission and “MT” = ManualTransmission.

mtcars$am<-as.factor(mtcars$am) levels(mtcars$am)<-c("AT", "MT")

Exploratory Data Analysis

Get The Mean of Automatic and Manual Transmissions:

aggregate(mpg~am, data=mtcars, mean)

##   am      mpg ## 1 AT 17.14737 ## 2 MT 24.39231

The mean MPG for manual transmissions is 7.245 which higher than automatic transmissioncars. Is this significant?

Validate Significance:

aData <- mtcars[mtcars$am == "AT",] mData <- mtcars[mtcars$am == "MT",] t.test(aData$mpg, mData$mpg)

## ##  Welch Two Sample t-test ## ## data:  aData$mpg and mData$mpg ## t = -3.7671, df = 18.332, p-value = 0.001374 ## alternative hypothesis: true difference in means is not equal to 0 ## 95 percent confidence interval: ##  -11.280194  -3.209684 ## sample estimates: ## mean of x mean of y ##  17.14737  24.39231

The p-value of the t-tst is 0.001374, with 95% confidence interval. There is a significantdifference between the mean MPG for automatic verses manual transmissions.

Histogram of the mpg for Automatic and Manual Trasmissions.

ggplot(data = mtcars, aes(mpg)) + geom_histogram() + facet_grid(.~am) + labs(x = "Miles per Gallon", y = "Frequency", title = "MPG Histogram for automatic verses manual transmissions")

## `stat_bin()` using `bins = 30`. Pick better value with `binwidth`.

Boxplot mpg for Automatic and Manual Trasmissions

ggplot(data = mtcars, aes(am,mpg)) + geom_boxplot() + labs(x= "Transmission", y = "MPG", title = "MPG: Automatic and Manual Trasmissions")

From this linear regression model of mpg against automatic, manual transmission have7.24 MPG more than automatic transmission. The R^2 value of this model is 0.3598,meaning that it only explains 35.98% of the

Using step function.

f2 = step(lm(data = mtcars, mpg ~ .),trace=0,steps=10000) summary(f2)

This model uses an algorithm to pick the variables with the most affect on mpg.From the model, the weight, acceleration as well as the transmission affect thempg of the car the most.Based on a multivariate regression model, a manual transmission cars have better fuelefficiency of 2.94 MPG higher than automatic transmission cars. The adjusted R^2of the model is 0.834, meaning that 83% of the variance in mpg is do to themodel.

ANOVA 2 Models

fstep<-lm(mpg~ am + wt + qsec, data = mtcars) anova(f1, fstep)

## Analysis of Variance Table ## ## Model 1: mpg ~ am ## Model 2: mpg ~ am + wt + qsec ##   Res.Df    RSS Df Sum of Sq      F   Pr(>F)     ## 1     30 720.90                                 ## 2     28 169.29  2    551.61 45.618 1.55e-09 *** ## --- ## Signif. codes:  0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1

The p-value indicates that we should reject the null hypothesis that the means from bothmodels are the same. That is, the weight and acceleration of the car have a significantimpact on it’s MPG.

Conclusion

In conclusion, holding the weight and acceleration of the cars as constant, manualtransmission cars offer 2.94 MPG better fuel efficiency.

par(mfrow = c(2,2)) plot(f2, col = 4)

By examining the plot of residuals, we can see that there are a few outliers,but nothing significant that would skew the data.
