Document Summary
1. 1 monty hall problem: host knows where the car is, know he won"t reveal the car, he will always show a goat, scenarios: If you always switch, then you end up winning 2 times out of 3. If you always stay, you have a worse chance. 1. 2 overview: getting into the course material: there are two main types of statistics. Inferential - want to reach a conclusion about population of interest: de nition: population. Population is made up of people, cars, objects, etc. Has a parameter - characteristic of the population i. e. average age of all ubc students. We can collect a sample from population. May not always be feasible to survey everyone in population - so use a subset (the sample) to make inference. Sample may not always be representative of the population: once we have a sample, can calculate the statistic, if we use statistic and sample in a graphical manner - descriptive.
