The standard error of the mean is 12.
The standard error of the mean points to the standard deviation of the distribution of a sample mean obtained from a population.
The standard error S.E of the mean can be calculated by using the formula:
where;
- standard deviation = 24
- sample size n = 4
S.E = 12
