Nov 20 Lesson 17
Test scheduled for tonight postponed, which means the following topics will be covered tonight
Mean deviation, Standard deviation,
Normal distributions; introduction to the Guassian curve or distribution, the easiest of the lot.
Terms to know
- symetry about the mean μ
- standard deviation sigma
- variance and the mean, how them modify the distribution curves; see graphs
- area under the curve
- variance
- Normalizing the Guassian curve in order to evaluate a defined area
