The Science and Business of Life Expectancy: The Probabilities of Life
by Jennifer Cooke
In this lesson two of four, students have to estimate and guess how much weight each of four factors has on a person's life expectancy, which often causes discomfort. They will ask you for direction with their guesses. Resist the urge to give them any direction on the size of their proportions. This is calculator heavy. Best practice is for you to complete the calculations prior to instruction. Recommend calculator fluency in running a goodness-of-fit test.
By the end of today’s lesson, students will:
Learn what a goodness-of-fit test and expected value model are in statistics
Test whether your idea of the relative influence of our 4 life expectancy factors is significantly different from the true influence of these 4 factors
