How Do You Calculate Central Limit Theorem?
In statistics, Central Limit Theorem problems usually contain the phrase “normally distributed.” What this means is that for the type of problem you are solving, the graph of the population looks like a “bell curve.” This comes in handy because you can make all kinds of assumptions about the shape of the population graph, without actually knowing much about the population at all. Central Limit Theorem problems usually ask you to figure out the probability of the mean (the average) being within certain limits (for example, greater than a number or in between two numbers). Read the problem to make sure that you understand the question. The question might tell you the population (for example, fifty-year-old women or all dog owners), the average (mean), the standard deviation (how the data is spread out), and a population sample size (for example, 20 people). Figure out if the question is asking you for the probability to be greater than, less than, or in between a certain number. This is
