Following a general introduction to Tukey's Jackknife technique and the construction of approximate confidence intervals, ten variants of the procedure are defined for giving interval estimates for coefficient alpha. A data base of known population characteristics was generated and used to compare the robustness of the ten Jackknife alternatives with Feldt's well-known sampling theory based upon the assumptions of normality. The empirical results indicate that out of the ten variants, defined by five transformations and two methods of data subdivision, only two are justifiable competitors to Feldt's approach.  相似文献

Male and female researchers separately interviewed the male and female heads of household in each of 159 homes in three villages in northern India. Analyses revealed consistent gender differences, such that women, compared to men, rated their homes more negatively, experienced more physical symptoms, and thought the supply of resources was insufficient. Surprisingly, women also believed that their homes could house more people and were significantly more likely to want more children. In other words, women reacted negatively to crowding but also appeared to like having many people in the household. Possible reasons for this apparent contradiction are discussed.  相似文献
