Central Limit Theorem
This lesson involves examining distributions of sample means of random samples of size n from four different populations.
Family of t Curves
This lesson involves investigating how a t-distribution compares to a normal distribution.
German Tanks: Exploring Sampling Distributions
In this lesson, students will estimate the largest number of a population based on random samples from the population, as statisticians did in WWII.
Why Divide by n-1?
Students will investigate calculating a sample variance using both n and n-1 as the divisor for samples drawn with and without replacement.
