This lesson involves investigating the differences between the standard deviations of sampling distributions of means for samples taken from finite populations with and without replacement.

This lesson involves examining distributions of sample means of random samples of size n from four different populations.

This lesson involves investigating how a t-distribution compares to a normal distribution.

In this lesson, students will estimate the largest number of a population based on random samples from the population, as statisticians did in WWII.

This lesson involves examining samples from a normal population and observing the distribution of the means of those samples.

This lesson involves investigating the relationship between the standard deviation of a population, the area of a set of rectangles, and the standard deviation of the sampling distribution of sample mean areas of the rectangles.

Students will investigate calculating a sample variance using both n and n-1 as the divisor for samples drawn with and without replacement.

This lesson involves examining the variability of individual elements and their related standardized test statistics when those elements are drawn randomly from a given normally-distributed population.
