Preview - Sampling Distributions 2021

Sampling by hand



Since we do a lot of small group work in AP Statistics, we’ve decided to sample 2 students from a group of 4 and take the average of their scores to get an estimate for how well students in this group performed on the exam.  **Note: usually people wouldn’t use a sample and population this small, but we’re starting small to help you visualize what we’re doing.**

For this scenario, our population will be 4 students with the following scores: Alexis - 3, Bert - 4, Chris - 5, Devin - 5


Questions

Please answer the questions below.

How many samples of size 2 can be taken from this population?


What is the parameter of interest for this situation?


What statistic are we using to estimate the parameter of interest for this situation?


Do you think taking a sample this size from this population effectively estimates the mean score of the population?
