##### how to Calculate Descriptive statistics using R

In this post I will explain you how to calculate basic descriptive statistics using R. The following R scripts helps to calculate descriptive statistics such as Mean, Median, Mode, Standard deviation, Standard error of the mean,Five-number summary, quartiles, percentiles, skewness and kurtosis.

Packages used are psych and Desctools

##Descriptive statistics using R## (www.iamsulthan.in) ##Packages used psych and Desctools

##Following commands will install the packages only if they are not already installed

if(!require(psych)){install.packages("psych")}

if(!require(DescTools)){install.packages("DescTools")}

#Load your data here

data("trees") ##loads data inbuilt in dataset package of R which includes Girth, Height and Volume for Black Cherry Trees

##structure of the data frame

str(trees)

##summary

summary(trees)

##mean

mean(trees$Height)

##median

median(trees$Height)

##mode

Mode(trees$Height)

##Standard deviation

sd(trees$Height)

##Standard error of the mean

sd(trees$Height) / sqrt(length(trees$Height))

##Five-number summary, quartiles, percentiles

summary(trees$Height)

##skewness and kurtosis

describe(trees$Height,type=3) #there are 3 options available u can see in package documentation for details
