Can this plug-in handle multiple reviews and display average scores?

In the description, the following is stated:

“Site Reviews allows your visitors to submit reviews with a 1-5 star rating on your website, similar to the way you would on TripAdvisor or Yelp.”

Does this mean that this plug-in can handle several reviews of the same product and display and average score? For example, if three different users rates a product with 3, 4 and 5 stars, respectively, will the plugin then display the average score of 4?

Thanks in advance for any feedback!
