How to guides for the TI 84

This link will help you find a maximum or minimum of a function.

This link will help you find the intersection of two functions.

Some review problems to help you prepare for the AQR Fall Final!

There is a lot of vocabulary associated with statistical investigations on this final, but there is also a lot of calculations.

After you finish reviewing the 10 activities found in Unit 3, try doing the following problems on your own. You will need a TI calculator.

Using the following data to find or make the:

1. Mean

2. Standard Deviation

3. Five number summary

4. Box and Whisker plot

5. IQR

6. An outlier

20,30,30,30,50,50,50,50,50,60,60,100

After you are finished, check your answers with a classmate!

Minimal Spanning Tree Algorithm Rubric.

Presentation Rubric for “another” algorithm for arriving at minimal spanning tree.

Your minimal spanning tree presentation must have:

___Definition of minimal spanning tree 

(10 points)

___A real world application for a minimal spanning other than Ethernet networks, trains, and bridges 

(10 points)

___Research and report on another algorithm besides Kruskal’s for arriving at a minimal spanning tree. 

(20 points)

The report should:

___ give the reader some background on the algorithm  

(20 points)

___and teach the reader how to make weighted network into a minimal spanning tree. Pictures are a must.

 (20 points)

___Compare and contrast your findings with Kruskal’s Algorithm as appropriate.

(20 points)

Data Set Assignment and Survey Design

I assigned a data set per group, so you will be working on data set 5, Diesel sales taxes by state, on page 41. There is a link for a map of America and the sales tax associated with diesel fuel found on the web page listed on pg 41.

####Please email me your finished product. I would like you to make a word doc this time.####

Use your calculator to randomly select 10 of the 51 amounts. Write down the name of each state and its sales tax on a gallon of diesel fuel.

Calculate the descriptive statistics for the data set and interpret all statistics. (5 number summary and mean)

Create a histogram in Excel. Explain what the graph tells you about the data.

Write a couple of sentences for the school newspaper about your results.

After you have emailed me your data analysis word docs, complete Survey Design p45 #1-3.

AQR Reflection

After you are finished with the test, I want you to reflect over the course you just took in the form of an email.

Please include the following with whatever else you wish to write in this email.

1. What were your expectations?

2. Did the course not meet/meet/ or exceed your expectations? Please explain your answer.

3. What made this course different than other math courses you took at AHS?

4. What was favorite topic? Why?

5. What was your least favorite? Why?

Email your reflection to sean.mcgrath@austinisd.org

AQR - Statistical Study - Day 1

You will complete the initial phase of your research study.

The outcomes of today are:

What are my questions/hypothesis?

What is my chosen sample technique?

The project topic should be fully fleshed out at the conclusion of today.

In order to be successful, I've attached the rubrics for the project and presentation. I would recommend downloading these files and getting accustomed with them before you start the project.
