This will give you the fastest turn around time and the greatest degree of complexity and sophistication in data analysis. Large surveys probably ought to be scanned into computers. In general, the faster the turn around time, the better. Waiting several months to get the results may mean that conditions have changed in the interim. Deciding on the Right Questions A survey is only as good as the questions it asks, so one of the most important decisions is that of determining what questions to ask in the first place.
Some issues are rather straight-forward and the questions are self evident.
However, test developers must avoid making the mistake of asking only what someone thinks are the important questions. For example, asking the sales department to develop the questions for a customer service survey is not a good idea. A much better approach would be to ask the customers what they think the important issues are. Focus groups are a great help in such cases. Survey results are usually reported in the form of tables, graphs and written comments.
