 More precisely, R is a programming language that runs computations while RStudio is an *integrated development environment (IDE)* that provides an interface by adding many convenient features and tools. So just as the way of having access to a speedometer, rear-view mirrors, and a navigation system makes driving much easier, using RStudio's interface makes using R much easier as well.

 So R is like a new mobile phone: while it has a certain amount of features when you use it for the first time, it doesn't have everything. R packages are like the apps you can download onto your phone from Apple's App Store or Android's Google Play.

 Again, such random shuffling of the gender label only makes sense in our hypothesized universe of no gender discrimination. How could we extend this shuffling of the gender variable to all 48 resumes by hand? One way would be by using standard deck of 52 playing cards, which we display in Figure \@ref(fig:deck-of-cards).

 Since half the cards are red and the other half are black, by removing 2 red cards and 2 black cards, we would end up with 24 red cards and 24 black cards. After shuffling these 48 cards as seen in Figure \@ref(fig:shuffling), we can flip the cards over one-by-one, assigning "male" for each red card and "female" for each black card.
