Hello,
Remove ind from the calculations.
And maybe substitute length(Variable) for 1312.
And standard deviations is the square root of the variance, you are
missing the square root.
Hope this helps,

Dear all,
I am trying to write the script to calculate the mean and the standard
deviation without using the functions mean and standard deviations since
morning. Someone can help
These scripts below are what i did but when i run and check with the function
mean and standard deviation it is not the same result
ind<-1:number of observations
Mean<-(1/number of observations*sum(Variable*ind))
Standard<-(1/Number of observations-1*sum(Variable -
((1/1312*sum(Variable*ind)))))
Thanks
