Discuss the concept of standard error and how it is useful to researchers.
What will be an ideal response?
Ans: Answer would ideally include: The standard deviation of the sample means is referred to as the standard error. The standard error of the mean tells us by how much we would expect our sample means to differ if we used other samples from the same population. This value, then, indicates how well our sample represents the population from which it was selected; obviously, the smaller the standard error, the better. With a smaller standard error, we can have more confidence in the inferences we draw about the population based on sample data. In reality, we certainly do not have the time or resources to select countless random samples, nor do we need to. Only the sample size and the sample standard deviation are required to calculate a good estimate of the standard error.
