The standard error is an estimate of the standard deviation of a statistic. This lesson shows how to compute the standard error, based on sample data.
Is there any command to find the standard error of the mean in R?
Standard deviation (SD) measured the volatility or variability across a set of data. It is the measure of the spread of numbers in a data set from its mean value and can be represented using the sigma symbol (σ). The following algorithmic calculation tool makes it easy to quickly discover the mean, variance & SD of a data set.
