This is not the repeated sampling one would use to get the standard deviation of the 5-sample mean. I want a standard deviation, and I want a sample size!

R Standard Error Lm And FINALLY... > source(file = "script2.txt") # or source(file = "script2.R") if necessary Scripts! The standard deviation of a zero-length vector (after removal of NAs if na.rm = TRUE) is not defined and gives an error.

sd(x) When we repeatedly sample from a population and calculate the standard deviation of the sampling distribution of the mean, should the standard error still be refered to as the standard R news and tutorials contributed by (600) R bloggers Home About RSS add your blog! The length() function counts NAs as data values and doesn't tell you. (Which is why we couldn't use it above--it would have given the wrong value for n.)
