AMean median
BStandard error
CMean variance
DMean range
Answer & Solution
Correct answer: B. Standard error
1. The sampling distribution has its own spread, distinct from the population's.
2. That spread is quoted as the standard error of the mean.
3. Calculator routines take the lower value, upper value, mean and standard error of the mean as their parameters.
4. It equals the population standard deviation divided by the square root of the sample size.
