In this video Dr. Bounds will introduce the topic of hypothesis testing and inferential statistics. It is possible to "guess-ti-mate" information about a population when you know something about a sample taken from that population. Notes are available to accompany the video.

In this video Dr. Bounds will discuss Type I and Type II errors that may occur when estimating population parameters based on a sample. Since there is never absolute certainty when testing a hypothesis there's always a possibility that you make an error. This discussion will explain what the errors are and why you should be aware of them. Notes are available to accompany the video. Click here to download 7.6 video notes
