This video is about the calculation of standard error in R program. In R software, there is no in build function to calculate standard error. So, the standard error in R can be calculated by creating a function in R. There are also some packages which have functions to calculate standard error. In this video, I have shown both ways to calculate standard error. The describe function within psych package gives summary of data along with standard error. I have also shown how to create a function to get standard error of data with missing value. The example of real data with missing values is also provided to compute standard error of mean.
