Scanning the Completed Questionnaires By default, the Snap Scanning Module will scan a questionnaire, deskew it, check for any misalignment, and then detect the values on the questionnaire creating Case data. The scanning of questionnaires is controlled by the Acquire dialog box. Scan and Detect Process For small volumes of questionnaires, 50 or less, scanning your questions and detecting the values at the same time is satisfactory. For large or high volume questionnaires, you may want to run these two options separately. It is recommended to scan in your questionnaires in small batches to help you identify errors if needed. 1. With the Paper: Scanning questionnaire open, click on the Data Entry icon ( ) on the main toolbar. 2. The Data Entry Questionnaire Mode will appear. Test Case will appear at the top of the window as shown to the right. 3. Click the New Case icon ( ) on the Data Entry Questionnaire Mode window. 4. The Acquire dialog box will appear. 5. Select Scan and Detect to complete both steps. 6. Select Print Batch Header to print information related to the batch of scanned questionnaires. 7. Place your completed questionnaires in the scanner as instructed by the scanner manufacturer. 8. Click OK. 9. When the scanning is complete, the Snap Scanning alert will be displayed asking you to check that the sheet feeder is empty. Press OK. 10. The Snap 9 alert will appear informing you that the auto detection, if selected in the Acquire dialog box above, is completed and will list the total number of sheets read and detected. Click OK. NOTE: A useful option is Print Batch Header, which generates a Batch Report listing the questionnaires that have been scanned from the current batch. The report lists date and time, together with the name of the survey, and the case numbers allocated within the survey. It is advisable to attach the Batch Report to each batch of questionnaires that have been scanned. They can be stored together so that, should there be a need to examine the questionnaires, it will be possible to confirm when the documents had been scanned, along with the case numbers to which they refer. 11 Miami s Survey Solutions
Verifying Data Results With the completed questionnaires scanned and detected, the next step would be to verify the data by using the Keying/Cleaning option. Keying involves the manual keying in of those replies that cannot automatically be detected by the scanner, for example open ended responses, dates and times. Cleaning checks that the replies recorded by the scanner are accurate and consistent. This looks for multiple check marks for the same question that is set for a single response, non numbers in a box designated for numbers, etc. Manually Verifying the Data Results 1. With the Paper: Scanning questionnaire open, click on the Data Entry icon ( ) on the main toolbar. 2. Click on the Prompted Mode icon ( ) on the Data Entry toolbar to switch to the Data Entry Prompted Mode, if needed. 3. The total number of Cases will be listed at the top of the Data Entry Prompted Mode window. An image of your scanned questionnaire will appear in the left hand panel with the data responses appearing in the right hand panel. Full Response View 4. Clicking on a question in either panel will highlight the question in the left hand panel and select the response in the right hand panel. 5. Double click a response in the right hand panel to access the Coded Response view and edit the response, if needed. 6. Press Enter to return to the Full Response view. 7.

Validation Failure will find any questions where a pattern matching has failed and so keying is also required. Validation Uncertain is where Snap has tried to find a pattern or spelling match and is unsure whether the answer given is correct. NOTE: If there are a lot of questionnaires to enter, a Filter can be applied to limit the range of cases to process. 3. In the Keying/Cleaning dialog box, click on the Cleaning tab and select the options you want performed. See below for a description of each option: Unrecognised detects entry boxes.
