Haya noticed that college students needed to dress up for presentations but never seemed to have any ties, or at least not very nice ones. she decided she was going to set up a tie store on her campus and offer sports themed ties as well as solid colored ties in her school colors. haya begins collecting data about her customers by having them sign up for promotional e-mails at her store. she collects their names and e-mail address on her form and keeps track of their purchases as well. she does some work with the data to understand what her customer behaviors are. that work would be considered ________________-.
