# Sample Exam is HERE

## Nov 18 Lesson 16

Frequency histogram or as the book says frequency diagrams

Grouped data will be ploted as a bar graph

Measurement of Central Tendancy

Measure of Spread, quartiles, Mean deviation

Will not spend must time on quartiles

Learn how your caculator handles **statistics**. This I probably cannot do for you!

- Page 296 # 1, 2, 5

## 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

## Nov 25 Lesson 18

Probability and Probability Tests is tonight

Review of last days material
Chebyshev's theorem and the *z*-score

- Page 316 # 1, 2, 4, 5, 7, 8, 11

## Nov 27 Lesson 19

I hope to leave a little early tonight, so show up around 6:10 or so

Normalizing the Gaussian curve, working with mu & sigma

Wrap on Statistics, test should be Dec 4

Introduction to Matrices chapter 8, will be done using examples before the algebra is introduced

Pay close attention to how matrices are designed and why

Setting up a matrix from a word problem

Adding if the matrices are of the same dimension & scalar multiplication,
