What is a Sampling Distribution?
Day 91 - Lesson 6.1
Distinguish between a parameter and a statistic.
Create a sampling distribution using all possible samples from a small population.
Use the sampling distribution of a statistic to evaluate a claim about a parameter.
Activity: Guess the midterm average. Part 2
Yesterday we created a sampling distribution of sample means. Students took samples, calculated the sample means and wrote each mean on a sticker for the dotplot. Today, students repeated the process for samples of size 10. Make sure to save your dotplot from the previous day to post them next to each other. You'll also want to use the same scale on the axes. Students noticed the variability of the dotplot decreased.
