I am reviewing this resource as a biology student, and I will specifically be discussing the "Chi Squared Test Review Worksheet" that is available as an Education Resource, provided by Winnie Litten. The worksheet is very basic and allows the student to follow along with the video and check their understanding as they go. It also insures that the students complete the problem posed at the end of the video. This is important for understanding, as a student I often feel that I understand a concept when watching an instructor do/explain it, but then when I try it myself I get confused or lost until I have more practice. It is a great video with a simple worksheet to check for understanding.
This video does a great job featuring the chi square material in a logical manner. It begins with defining the not only key phrases (degree of freedom, critical values, null hypothesis, and the different variables in the equation, ) but it also briefly explains why and how we came to use these terms. Being a visual learner, I enjoyed the broadcasts's use of images, text, note-taking,charts, and sub videos. The length of the video was about twelve minutes which the creator used appropriately; he paused at certain times to allow the viewer's brain to process the information given. The only slight change that I could see,would to take another minute in describing the null hypothesis in respect to the examples. The null hypothesis is very important to chi square problems and should be described with a sentence or two more about how it directly effects an experiment.
