The main aim of this project was to investigate the relationship between funerary object numbers found in single tombs and the sex, the age of the deceased and the period of the tomb. Based on the actual situation, statistical analysis was carried out using different methods, such as the t-test, chi-squared test and between-subjects effects test. The results suggested that the total quantity of funerary objects is not related to the sex of the deceased, but to the owner''s age at death:those died in their prime had more objects. There are notable correlations between total quantity and the deceased person''s sex and age:female children had the most articles, followed by males in their prime. The young and children had the most in total, females in their prime had more stone objects, and males in their prime had more bone and tooth objects. The quantity of pottery, bone and tooth objects varied significantly with the tomb period was found also. During period II, there are more pottery, bone and tooth objects. The research results suggested that the larger quantity of funerary objects found in female children''s tomb could be explained assuming that females were valued higher in a matriarchal society. The reason females and males in their prime had different categories of funerary objects could possibly be interpreted on the basis of the division of labor among those ancestors who lived in Jiahu area. The higher quantities of pottery, bone and tooth objects found in period II tombs might be related to active hunting and gathering behavior during this period.
