Why Is Sample Selection Valuable?

If you wanted to know how tall the average male was in the US, you could measure all 150 million guys. During the study period there would be births and deaths while you were accomplishing the measurements so you would have to account for that. Or you could take a sample carefully designed so that the measurement of the fellows in your sample resulted in nearly identical measurements to those in the population of US males. Research Design Associates are expert in navigating through research projects and selecting the right sample for the task.
