DATA ELEMENT vs DATA ELEMENT:
|
consider analysis where amount of a sale is correlated to whether the sale is paid for in cash or with a credit card. When a sale is below a certain amount, it is found that the payment is made with cash. When the sale is over a certain amount, the payment is made with a credit card. When the sale is within a certain range, it may be paid for either way.
