This study examined the effects of food servers' sex, the use of generalized compliments, and the size of the dining party on tipping behavior in restaurants. Four food servers (2 males, 2 females) waited on 360 parties eating dinner, and either complimented or did not compliment the parties on their dinner selections. Results indicated that food servers received significantly higher tips when complimenting their parties than when not complimenting them, although as the size of the party increased, the effectiveness of compliments decreased. These results and their implications are discussed. 相似文献

Maydeu-Olivares and Joe (J. Am. Stat. Assoc. 100:1009–1020, 2005; Psychometrika 71:713–732, 2006) introduced classes of chi-square tests for (sparse) multidimensional multinomial data based on low-order marginal proportions.
Our extension provides general conditions under which quadratic forms in linear functions of cell residuals are asymptotically
chi-square. The new statistics need not be based on margins, and can be used for one-dimensional multinomials. We also provide
theory that explains why limited information statistics have good power, regardless of sparseness. We show how quadratic-form
statistics can be constructed that are more powerful than X
2 and yet, have approximate chi-square null distribution in finite samples with large models. Examples with models for truncated
count data and binary item response data are used to illustrate the theory. 相似文献

This study examined the commonalities and the differences between creativity and the schizophrenia spectrum. The variables measured were creativity, schizotypy, absorption, mystical experiences, spatial ability, balance, positive and negative presence, and neuroticism. Three community groups were recruited: 31 artists, 10 people with schizophrenia, and 31 comparisons matched for gender and age with the artists. A larger student group, consisting of 102 students, was also recruited to examine the correlations among the same variables within a larger, more normative, group. The largest commonality between the artist and the schizophrenic groups was the propensity to mystical experiences. The greatest differences between them were that the artists were higher in creativity, had better spatial ability, had better balance, had more positive states of presence, and were lower in neuroticism. In the student group, creativity was positively correlated with positive schizotypy, impulsive nonconformity, spatial ability, positive presence, absorption, and mystical experiences, although in the student group, the relation between creativity and mystical experiences was completely mediated by absorption. 相似文献
