A company sells wearable exercise monitors. They sell two models that increase in functionality: the i100 and i500:
i100: heart rate, GPS (to compute miles per hour, etc), wifi to automatically connect to their website to upload data
i500: i100 features + pulse oximetry (oxygen in blood) + free 3G connection to the website
They sell these online and they need a recommendation system for their customers. To get data to build the system when someone buys a monitor, a questionnaire is supplied to be filled out. Each question in the questionnaire relates to an attribute.
Questions asked:
1) Main reason for starting an exercise program – health, appearance or both
2) Current exercise level: sedentary, moderate, or active
3) Motivation level: moderate or aggressive
4) Comfortable using technological devices: yes or no
