Appendix A, "Data Analysis When Students Change from Smaller to Larger Schools between the Pre-test and Post-test of the First Year," discusses a methodological problem involved in planning the approximate number of questionnaires to be administered in program. Appendix B, "Estimates of Sample Sizes and Data Collection Costs," includes five tables. Tables 1 and 2 show estimated numbers of schools, students, and teachers for each year of the program. Table 3 shows an approximate cost estimate for data collection, and Table 4 indicates how sample sizes would change if the experimental version of the study were used. Table 5 gives the costs of implementation of the experimental innovations. Appendix C contains basic questionnaires and test batteries to be used in the various surveys. These include student questionnaires, noncognitive outcomes, teacher questionnaire, principal questionnaire, superintendent questionnaire, parent questionnaire, community leadership questionnaires, bibliography, and classroom observation instruments. Appendix D describes Jessen's Method 2 for unequal probability sampling as well as for probability lattice sampling. Also discussed are options that enhance flexibility, involving cell size, zero cells, multidimensions, unequal margins, and noninteger margins. The "Replicability of Results" problem is also examined. (Author/JM)
