Hello ETF investors, welcome to our community! If you are interested in learning how to collect data for the RATER criteria, here are some tips and resources for you.

The RATER criteria are five dimensions of service quality: reliability, assurance, tangibles, empathy, and responsiveness.
To collect data for these criteria, you can use various methods such as surveys, interviews, focus groups, observations, or mystery shopping. For example, you can ask your customers to rate your service on a scale of 1 to 5 for each dimension, or you can observe how your staff interacts with customers and note their behaviors and expressions. You can also hire mystery shoppers to pose as customers and evaluate your service from their perspective.

I hope this helps you understand how to collect data for the RATER criteria. Feel free to ask any questions or share your experiences in the comments section. Thank you for being part of our community!
