Bridge Math 2.8 Measures of Central Tendency: the Average or Mean

The "Mean" is just another name for average. To find the mean of a data set, add all the values together and divide by the number of values in the set. The result is your mean! To see an example of finding the mean, work through the video with me.

Short review of Complex (imaginary) Numbers



Watch the next 2 videos - and write a short (1/2 page) description of Fractals, how they might be used, and where you might find them in nature.  Do you think Complex Numbers play a large part in the behavior of Fractals like the Mandelbrot Set?
