Identify the level of measurement of the data and explain what is wrong with the given calculation. In a set of data, movie ratings are represented as 100 for 1 star, 200 for 2 stars, and 300 stars for 3 stars. The average (mean) of the 527 movie ratings is 231.2.

I got ordinal for the level of measurement,but I don't know what is wrong with the given calculation. Is there not enough information present to get a mean?
