•You have two datasets –302 from bank sales personnel and 611 from customers. What is not clear is how these two datasets were used. Were they combined? If yes, where they checked for consistency or similarities? If the data sets were not similar then they should not be combined. However, if the datasets were not combined, then I don’t see any evidence of these being treated differently.
