On Building an A-Posteriori Index from Survey Data: A Case for Educational Planners' Assessment of Attitudes towards an Educational Innovation.
Vazquez-Abad, Jesus; DePauw, Karen
To simplify data from a large survey, it is desirable to classify subjects according to their attitudes toward certain issues, as measured by questions in the survey. Responses to 12 questions were identified as indicative of attitudes toward deschooling education. These attitudes were explained by means of patterns exhibited within the responses given to some questions which best discriminate between people for and against deschooling education. Because limited relevant information is available on this subject, the approach taken was to build an a-posteriori index to describe the attitude under study. The index was obtained by running a canonical correlation between a set containing information from the 12 attitudinal questions, and another set containing information from 52 explanatory questions that were most relevant to the study. This analysis produced canonical variates and each of these was taken as the index for each set. Based upon actual distribution of index values, subjects were associated with a "clearly against,""clearly for," or "other" attitude toward deschooling education. A discriminant analysis was run on the 52 "explanatory" questions to assess which of these could best account for the difference between groups. The meaning and value of the results are discussed.
