Highway 10 Connexus

Grade 12 students in Manitoba learning Applied Math... They're in two different towns, and happen to be connected by Highway 10...They'll be learning with and from each other. Ryan Maksymchuk and Cam Bennet are teachers in Swan River and Dauphin, Manitoba, respectively. This is a bright idea that may encourage other teachers and students to consider collaborating with other learners in other places...It might work. It might not...Watch and see...

March 11th Lesson

Helllo! well today in class we learned alot..... ha.
today we learned about Percentiles and what they are used for and do.
Example 1: 80 percentile
--> Means that you are better than 80% of the population
Example 2: 100% percentile
--> Means you are 100% the BEST! whoo

We had also learned about Invert Norm which is the opposide of shade norm.
*Given the shaded area, invert norm returns or gives back the z score that would shade that are.
..Do you understand?
*Shade Norm you know the z-score and want to know the percent%
*Invert Norm you know the percent% and want to know the z score

To find Shade Norm on your calculator you hit:
2nd DISTR -> DRAW 1:ShadeNorm(

To find Invert Norm on your calculation you hit:
2nd DISTR 3: invNorm(

Today for work we got a hand out called excercises standard normal distributions and were to do numbers 1-15 and also got another hand out called invert norm questions and were to do numbers 1-6.

well thats it for today.. peace
