Population vs Sample. The main difference between a population and sample has to do with how observations are assigned to the data set. 1  A population includes all of the elements from a set of data.2  A sample consists of one or more observations from the population.opulation vs Sample.

For a population with unknown mean and unknown standard deviation, a confidence interval for the population mean, based on a simple random sample (SRS) of size n, is + t* , where t* is the upper (1-C)/2 critical value for the t distribution with n-1 degrees of freedom, t(n-1).f the measurements follow a normal distribution, then the sample mean will have the distribution N(,) . Since the sample size is 6, the standard deviation of the sample mean is equal to 1.2/sqrt(6) = 0.49.
