The lab instructor will take you to a cemetery. Work in groups of about two students. One of you can record the data, and the other can work with a calculator to find out how old each individual was when they died. The lab groups should divide up the area of the cemetery so that all areas are sampled, but none are sampled more than once. To determine sex, examine the individual's name.
Some names are obviously male or female.
Work as quickly as you can, but also be careful to show respect for where you are. Stick to the pathways. On the chalk board, total up the number of deaths at each age for everyone in your lab from each cemetery that you studied. Remember to keep the sexes separate. You can estimate survivorship by dividing each n x by n 0 .
