Question

Researchers studying anthropometry collected body girth measurements and skeletal diameter measurements, as well as age, weight, height and gender, for 507 physically active individuals. They found that subjects had a mean height of 171 cm with a standard deviation of 3.5. The sample means obtained are point estimates for the mean height of all active individuals, if the sample of individuals is equivalent to a simple random sample. What measure do we use to quantify the variability of such an estimate?

Explanation / Answer

Solution : ( a ) Standard Error

We would use the Standard Error for the sample mean to quantify the variability of the estimate.
