Lesson Topic
Standard deviation - Final Review
Lesson Outline
in wrapping up this year's work, we looked again at the formula for the standard deviation of a data set, and more importantly how to use it. The standard deviation describes exactly what it says: by how much each element in the data set deviates from the mean of that data set. Jared worked through an example on the board, by first identifying the steps required to perform the calculation, i.e. finding the mean of the data set, the difference between each element and the mean, the square of each of the latter, the sum of the squares which is then divided by the number of elements, and the square root of all this.

Lesson Comments
Jared was - thankfully - in a much better mood than yesterday, but he still grumbled when I asked him to do the calculations on the board instead of using the STAT feature on the calculator. I had asked him to work through this one example with no prompting from me (I had struggled to get him to work on this in the past - the standard deviation is a fundamental concept in Statistics) yet he still needed my help… I pointed out to him that he can use the STAT feature on the calculator when he understands the principle behind calculating the standard deviation.
