I found this math video on basic statistics useful. The material was specific and comprehensive. Being able to watch the calculations on the whiteboard was helpful. And if necessary, one is still able to learn by listening to the video, like a podcast, as one attends to other things on desktop. I recommend this video on central tendency. However, the vid did have its drawbacks: * Many of the examples were not specifically relevant to the reader, in this case high school and higher education students. 1 billion dollars is not something I can envisage, at least not on its own. In the context of celebrity spending or government budgets I could grasp the score being used for analysis. Though, even then this amount of money is not really relevant to my social circumstances. Perhaps instead using examples which draw from my everyday world; 1) my assignment at uni is to describe a group in a research report. a group of people earning a wide range of wages gathered in one place would likely occur at an airport. I go to the airport and observe people and try to guess their age from their clothing, luggage and body language (of course, I base these assumptions on a variety of literature). 2) Calculating my shopping bills across three months to set up a Household Budget; tracking my grades to determine my GPA; monitoring my physical activity, intake and emotional development for optimum health; To complement the wealth of information presented by this video, the glossary of terms could be defined at a deeper level, to link the relevance of statistical tasks to scholastic studies, future careers and community contribution. More pictures~ especially the humorous to provide additional mnemonic aids. In this way I think that this detailed math video could add Value to the Learner's experience. As a statistics tutor, I have found demonstrations of the value of theoretical concepts used in stats to enlighten that, when used appropriately, theoretical values provide additional Meaning & Value to phenomenon.
