MA19.A2.31
Evaluate the effect of sample size on the expected variability in the sampling distribution of a sample statistic.

Unpacked Content

Knowledge

Students know:

Techniques to find the mean and standard deviation.

Skills

Students are able to:

Accurately compute the statistics needed.
Reach accurate conclusions regarding the population from the the sampling distribution of a sample statistic.

Understanding

Students understand that:

The center is not affected by sample size. The mean of the sample means is always approximately the same as the population mean.
As the sample size increases, the standard deviation of the means decreases. and as the sample size decreases, the standard deviation of the sample means increases.
