##Question 1

6*7
## [1] 42

Creating variables and objects

x <-6
y <-7
z <- (x*y)

Calculate the log of z

log(z)
## [1] 3.73767

##Question 2

sum of variables x and y

sum(x,y)
## [1] 13

This is the sum function. It added the value of the two variables together, six plus 7 equals 13.

##Question 3

Create a vector named v made up of 2,4 and 6 then run v +5

v <- c(2,4,6)
v +5
## [1]  7  9 11

This added 5 to each of the mathematical values in the vector, 2+5 equals 7, 4+5 equals 9, 6 + 5 equals 11.

##Question 4

Create an object called favorite_movie Using STAR data file, calculate the median of the math variable.

STAR <- read.csv("STAR.csv")
View(STAR)
favorite_movie <- "Fools Rush In"
summary(STAR)
##   classtype            reading           math         graduated     
##  Length:1274        Min.   :527.0   Min.   :515.0   Min.   :0.0000  
##  Class :character   1st Qu.:602.0   1st Qu.:604.0   1st Qu.:1.0000  
##  Mode  :character   Median :629.0   Median :631.0   Median :1.0000  
##                     Mean   :628.8   Mean   :631.6   Mean   :0.8697  
##                     3rd Qu.:654.0   3rd Qu.:659.0   3rd Qu.:1.0000  
##                     Max.   :753.0   Max.   :774.0   Max.   :1.0000

Math Median is 631.0
