In addition, we briefly examine OLS regression analysis. Many readers will already be fully conversant with OLS and will have no need to consult this section. Several sections of this manual assume a basic knowledge of OLS regression analysis. To facilitate the management of data, the questionnaire must be set out so that coding and data input are made as simple and efficient as possible. That issue is discussed in this chapter, and then we proceed to an examination of the processing of responses once they start to be received. The following section discusses the input of data to Whatever means of analysis are to be used when researchers are satisfied that few more responses will be received. Design to Facilitate Coding To facilitate analysis, responses to most questions on a survey instrument are coded in a numeric form. Efficiency and ease of data coding and input are directly related to the layout of the questionnaire. For example, where information is needed about the types of expenses incurred other than those in a given list, a dotted line might be placed to the left of the column and space left at the right for a code to be written in so that it can be easily read by the data...
