Answer to Question 1

Sources of data errors include appending, truncating, transcripting, and transposing. Appending is the addition of extra characters to a field. Losing characters from a field is called truncating. Transcripting is defined as entering invalid data into a field. Transposing involves reversing the sequence of one or more characters in a field.
