Ivoryweight


Some people buy products made of ivory (elephant tusks). Hence there is temptation to kill tusker elephants illegally (poaching). There is international agreement that police should arrest such poachers as well as traders in ivory or products made from it. The intention is to reduce illegal killing of elephants so that their populations are preserved. The data give number of pieces and weight of ivory confiscated.
It is of interest to see if there is a change in the ivory trade over the time, both in terms of pieces and in terms of weight. It is also of interest to check the relationship between number of pieces and weight. The analysis may be done for three stages raw, semi worked and worked separately or for total weight.
