It’s usually denoted by N. If the population is very large, it can be very expensive to carry out the investigation. All the elements we will perform in the study are called population. Basic Concepts of Measurement Before you can use statistics to analyze a problem, you must convert the basic materials of the problem to data. You should not confuse this concept with the population of a city for example. variable, and possibly under what conditions. Our emphasis is on applications in science and engineering, with the goal of enhancing modeling and analysis skills for a variety of real-world problems.
