Data Collection : Automatic Entry

Data collection can be speeded up if a direct data entry device is used to transfer the data from the data collection form into the computer. Appropriate methods for doing this are :

• Optical Character Recognition
• Optical Mark Recognition
• Bar Codes

If one of these methods is used then the data collection form must be designed specially for the method. The type of question that can be asked may also be restricted. For example if O.M.R. is used then questions can only be answered by making a mark in a box. Questions such as "What is your name ?" can not be asked easily.

Using a direct data entry device to input the data will eliminate the possibility of the data being incorrectly typed into the computer by the user.

Sometimes the data collection form has some information preprinted onto it by the computer. After the form has been completed the extra data added by a human is entered into the computer. This type of data collection form is known as a turnaround document.
