Question
Use R to obtain the following summary statistics for each method: mean, median, standard deviation, variance, and interquartile range. How do you do this? I keep on getting an error? It uses R software

Firstly, I copy the data that you have provided into an Excel file and convert the file to a .CSV file. The R code now has been pasted below.
# LOADING THE DATA SET ONTO R
data = read.csv("C:\Users\LAPTOP\Desktop\Book1.csv")
# SUBSETTING THE DATA INTO 3 DATASETS, CORRESPONDING TO THE 3 METHODS
data1 = subset(data,Method == "Control",select=c(No.jumps,Distance.travelled.cm,Duration.jumping.s,Longest.jump.cm))
data2 = subset(data,Method == "Air",select=c(No.jumps,Distance.travelled.cm,Duration.jumping.s,Longest.jump.cm))
data3 = subset(data,Method == "Recovery",select=c(No.jumps,Distance.travelled.cm,Duration.jumping.s,Longest.jump.cm))
## FOR DATA 1
# SUMMARY STATISTICS OF THE VARIABLES CORRESPONDING TO THE "CONTROL" METHOD
mean(data1$No.jumps)
median(data1$No.jumps)
sd(data1$No.jumps)
var(data1$No.jumps)
IQR(data1$No.jumps)
mean(data1$Distance.travelled.cm)
median(data1$Distance.travelled.cm)
sd(data1$Distance.travelled.cm)
var(data1$Distance.travelled.cm)
IQR(data1$Distance.travelled.cm)
mean(data1$Duration.jumping.s)
median(data1$Duration.jumping.s)
sd(data1$Duration.jumping.s)
var(data1$Duration.jumping.s)
IQR(data1$Duration.jumping.s)
mean(data1$Longest.jump.cm)
median(data1$Longest.jump.cm)
sd(data1$Longest.jump.cm)
var(data1$Longest.jump.cm)
IQR(data1$Longest.jump.cm)
## FOR DATA 2
# SUMMARY STATISTICS OF THE VARIABLES CORRESPONDING TO THE "AIR" METHOD
mean(data2$No.jumps)
median(data2$No.jumps)
sd(data2$No.jumps)
var(data2$No.jumps)
IQR(data2$No.jumps)
mean(data2$Distance.travelled.cm)
median(data2$Distance.travelled.cm)
sd(data2$Distance.travelled.cm)
var(data2$Distance.travelled.cm)
IQR(data2$Distance.travelled.cm)
mean(data2$Duration.jumping.s)
median(data2$Duration.jumping.s)
sd(data2$Duration.jumping.s)
var(data2$Duration.jumping.s)
IQR(data2$Duration.jumping.s)
mean(data2$Longest.jump.cm)
median(data2$Longest.jump.cm)
sd(data2$Longest.jump.cm)
var(data2$Longest.jump.cm)
IQR(data2$Longest.jump.cm)
## FOR DATA 3
# SUMMARY STATISTICS OF THE VARIABLES CORRESPONDING TO THE "RECOVERY" METHOD
mean(data3$No.jumps)
median(data3$No.jumps)
sd(data3$No.jumps)
var(data3$No.jumps)
IQR(data3$No.jumps)
mean(data3$Distance.travelled.cm)
median(data3$Distance.travelled.cm)
sd(data3$Distance.travelled.cm)
var(data3$Distance.travelled.cm)
IQR(data3$Distance.travelled.cm)
mean(data3$Duration.jumping.s)
median(data3$Duration.jumping.s)
sd(data3$Duration.jumping.s)
var(data3$Duration.jumping.s)
IQR(data3$Duration.jumping.s)
mean(data3$Longest.jump.cm)
median(data3$Longest.jump.cm)
sd(data3$Longest.jump.cm)
var(data3$Longest.jump.cm)
IQR(data3$Longest.jump.cm)
