How a Normal Distribution Affects the Shape of a Sampling…

The distribution of sample means is normal irrespective of the distribution of the true population.

A distribution of means is normal REGARDLESS of the parent distribution.

How to Find the Sampling Distribution of a Sample Proportion

very important in the world of statistics, the sampling distribution.

Accuracy and Precision in Terms of the Sampling Distribution

The larger the sample size (n), the closer the distribution of the sample means will be to a normal distribution.

Confidence intervals may be inferred based upon sampling distributions for a statistic.

approaches a normal distribution as the number of observations increases.

Sampling distribution theory tells us that p will have a distribution that can be calculated from the binomial theorem.

In the figure below, we have superimposed the sampling distribution for p when = .55.

Confidence intervals may be inferred based upon sampling distributions for a statistic.

Specifically, students will be exposed to the concepts of statistical inference, probability, probability distribution, sampling distribution, estimation, and hypothesis testing.

The region of rejection is on only one side of the sampling distribution in a one-tailed test.

The standard error of a statistic is the standard deviation of the sampling distribution of that statistic.
