The Robey dataset in the car library package looks at Fertility and Contraception in developing nations around 1990.

(a) Generate side-by-side boxplots to compare contraceptors for different regions. Label the axes accordingly and provide a title. Which region has the highest median percentage of contracep-tors?

(b) Plot the percent of contraceptors among married women of childbearing age versus total fertility rate. Make sure to appropriately label your axes and provide a title. Is there an association between these two variables? If so, what kind of trend do you see with respect to the variables in question?

Solution

(a)

Latin Amer region has the highest median percentage of contracep-tors

R-coding is

Africa=c(35,9,16,13,27,6,5,75,4,6,12,9,21,10,12,5,15,45)
Asia=c(40,72,45,50,77,12,34,62,68,53)
Latin.Amer=c(47,32,66,66,70,56,53,47,23,10,55,55,58,48,59,54)
Near.East=c(40,35,42,51,60,7)
boxplot(Africa,Asia,Latin.Amer,Near.East, main=\"contraceptors\", names=c(\"Africa\",\"Asia\",\"Latin.Amer\",\"Near.East\"))

(b)

x=c(35,9,16,13,27,6,5,75,4,6,12,9,21,10,12,5,15,45,40,72,45,50,77,12,34,62,68,53
