I found it difficult to interpret some of the statistics I got. For example, what does the average (Avg) of population of a state mean?
TranStats provides some basic statistical analysis. For quick information, the tool is powerful. However, like all statistics tools, the interpretation of the numbers depends on the knowledge of the data and how calculation is performed. AVG in TranStats is the sum of values divided by the number of non-null records in the database. In the case you just cited, the answer lies in what each record in that data table represents. TranStats cannot and does not exclude combinations of filter selections that may not make sense. You have to make the decision of what filter selections to choose.
