Answer:
a more inexpensive and quick way to receive and process results
Step-by-step explanation:
Online surveys are cheap because in most cases they can be freely sent and distributed on the internet, for example, to the e-mails of the customers.
And they are also easy to process. Finally, they are likely to be responded by many customers as long as they are not too complicated or bothersome. For this reason, they should be short, have very concise and clear questions, and offer privacy to customers if necessary.
The results can be easily analyzed manually or with specialized software.
