  1. Compare the salaries of graduates and non-graduates using a boxplot.
ceo$grad <- as.factor(ceo$grad)
qplot(grad, lsalary, data =ceo, geom= "boxplot", colour=I("coral"))

#It can be seen, that on average, the salaries of graduates and non graduates seem to be the same, however, for non graduates, the minimum and maximum value is higher than that of graduates. There seems to be outliers, one over the highest value for non graduates, and the other under the lowest value of graduate's salaries.   
  1. Compare the salaries of college-educated CEOs and others.
ceo$college <- as.factor(ceo$college)
qplot(college, lsalary, data =ceo, geom= "boxplot", colour= I("magenta"))

#According to the boxplot, the median salary for non college graduates is higher than that of college graduates, however, the maximum value overall is in the salaries of the college graduates, as well as the minimum. The outliers in the data are part from the graduate group, which could influence on the mean.
  1. Comment on the relationship between salary and age for graduates and others.
g <- ggplot(ceo, aes(age,lsalary))
g + geom_point() + 
        geom_smooth(method = "lm") +
        facet_grid(. ~ grad) 
## `geom_smooth()` using formula 'y ~ x'

#As it can be seen, there is no apparent relation between salary and age in non graduates, since the line is almost flat, however there seems to be a positive relation between salary and age in graduates (when age increases, salary increases).
  1. Comment on the relationship between salary and tenure for graduates and others.
g <- ggplot(ceo, aes(ceoten,lsalary))
g + geom_point() + 
        geom_smooth(method = "lm") +
        facet_grid(. ~ grad) 
## `geom_smooth()` using formula 'y ~ x'

#For both of these groups, it could be said that there is a positive relation between salary and tenure, however, this relation seems to be stronger for non graduates, with a more notorious slope.
