Looking at statistical numbers such as mean, or the average number, mode, or the most frequent number, or median, or the middle number, helps managers monitor business activities and make decisions. Often numbers themselves do not show the big picture, so ratios, or numbers representing relationships are used. Perhaps you're a regional manager who oversees 15 different car dealerships. You will keep track of sales per month, number of vehicles sold, number of salesmen, sales per person, operational costs, delivery times, and other information. You use this statistical information to look at trends, understand relationships between numbers, and make sound business decisions. Perhaps you need to shift a sales member to a different store, or realize that you need more available stock during certain months, all of which helps maximize the company's resources and profit.

Or, perhaps, you're a regional store manager and are concerned about how long customers have to wait to check out. Currently, customers queue in multiple lines with a single cashier. You measure the mean length of time for customers to complete their transaction for a month. Then the next month, you line up customers in a single line with multiple cashiers and measure the mean length of time for the transaction. You notice that even though customers take longer to walk to the next available cashier, the overall transactions are reported faster.

When the company expands and builds the next store, you specifically request it to be designed with one queuing line, using your findings to substantiate the request. Use of Inferential Statistics Inferential statistics help managers draw conclusions based on limited data. When predicting the future, we don't have a magic crystal ball, but we do have statistical strategies, such as sampling, probability, and models. Marketing departments often use inferential statistics. A company might issue a survey and ask questions about their products. However, it's impossible to survey every individual customer. The marketing department will determine the appropriate sample size, or the number of people to ask.
