This project work conducts a study on graduation of mortality rate using difference equation. The study illustrated the use of difference equation with an example solved manually and with the use of SPSS statistical software. The study started by introducing graduation, smoothness, mortality rates and some measures of mortality. We also looked at the methods of graduation, types of graduation and their advantages and disadvantages. We also looked at the test of graduation, where we considered two test which are the sign test and the chi-square test. Furthermore, the study looked at the meaning of difference equation, and we saw a few examples of difference equation. Methods of solving difference equation were also looked into Finally, illustrations were used to show how graduation of mortality rates works and results showed how we can predict ones death by how old he/she lives using the provided datasets.
