If I wanted to estimate the variability of sample means 
, I would calculate ______.
A) the standard error of the mean 
B) the standard deviation (s)
C) z-scores
D) the population mean (μ)
Sample Means
The average values calculated from samples drawn from a population; used in inferential statistics as estimates of the population mean.
Population Mean
The average value of a characteristic in the entire population being studied.
Standard Deviation
A metric indicating the extent of difference or scattering among a series of figures.
- Understand the concept and calculation of standard error of the mean.

Final Answer :
A
Explanation :
To estimate the variability of sample means, we need to calculate the standard error of the mean. The formula for the standard error of the mean is s/√n, where s is the sample standard deviation and n is the sample size. This gives us an estimate of the variability of means if we were to take many random samples from the population.
