Information Systems PaperUniversity of PhoenixCIS/319 Accuracy of data input is important. What method of data input would be best for each of the following situations and explain why:Printed questionnaires- The best method of data input would be a keyboard and mouse. One can enter many types of data and use the mouse to click, drop and drag symbols or other pieces of data that will help develop any specific design one needs. There are also many software programs available to help one design the appropriate format still using the keyboard and mouse.Telephone survey - A voice input device would work well for phone surveys in that one could prepare a specific survey and set up the device for voice recognition.
