Our ability to answer questions such as these and draw conclusions from data depends largely on our ability to understand variation. That may not be the term you expected to find at the end of that sentence, but it is the essence of Statistics. The key to learning from data is understanding the variation that is all around us. Data vary. People are different. So are economic conditions from month to month. We can’t see everything, let alone measure it all. And even what we do measure, we measure imperfectly.
Even so, when you phone an 800 number to buy new running shoes, customer service representatives may call you by your first name or ask about the socks you bought six weeks ago. Or the company may send an e-mail in October offering new head warmers for winter running. This company has millions of customers, and you called without identifying yourself. How did the sales rep know who you are, where you live, and what you had bought? The answer to all these questions is data. Collecting data on their customers, transactions, and sales lets companies track inventory and know what their customers prefer.
Be careful. Even if people are involved, the cases may not correspond to people. 2, each row is a different order and not the customer who made the purchases (notice that the same person made two different orders). A common place to find the who of the table is the leftmost column. It’s often an identifying variable for the cases, in this example, the order number. If you collect the data yourself, you’ll know what the cases are and how the variables are defined. But, often, you’ll be looking at data that someone else collected.
