**Key Concepts: Ch 1-16 Ch 16-22
**

Discover the chi-square test of independence (see class notes here). Complete the chi-square inference guide here.

Homogeneity - many groups asked 1 question (question = variable, answers = categories)

Independence - one group asked 2 questions.

1) pg. 642-648 / 23, 24, (problem 23 think back to what we did at the beginning of the year. We tested for independence with segmented bar charts then with P(A) = P(A|B). Now the independece X2 test provides "wiggle room" to accomodate natural sampling variability.)

However, with a low X2 value (and high p-value) we don't declare independence we only declare their isn't evidence of an association. (Makes me think it should really be called chi-squared test for association).

2) Study for Monday's chi-square quiz (Days 34-37)

**Tuesday 3/19 Day 36)** Discover another chi-square test, homogeneity (and the associated TI shortcut - see below).

**A36:**

1) pg. 642-648 / 28 (Show A/C, make a complete table, and show the X^2 calculation), 32, 33, 35

See the calculator shortcuts below:

**TI83+ or TI84 Homogeneity:** enter Obs into a matrix. 2nd,
x^-1, arrow to EDIT, ENTER, define the table size #rows ENTER, #col ENTER,
Now fill in the Obs countsans press 2nd, MODE (QUIT) to exit.

STAT, arrow to TESTS, C:X2-Test, Observed: [A], store Expected: [B], select Draw
or Calculate.

**TI89** **Homogeneity: **enter Obs into a matrix. APPS, 6:Data/Matrix Editor,
right arrow, 3:New, Type:right arrow to select Matrix, Folder = main (default),
Variable = enter name for matrix, Row = , Col = , ENTER. Now fill in the Obs
counts and press 2nd,ESC (QUIT) to exit.

Statistics app, 2nd+F1 for the Tests menu, Select 8:Chi2 2-way, Enter the name
of the Obs matrix (VAR-Link (2nd,-)) and find the name given. Store Exp and Store
Comp = defaults, select Draw or Calculate.

To view the Expected Counts: APPS, 6:Data/Matrix Editor, right arrow, 2:Open,
ENTER.

Type: Matrix, Folder: statvars, Vairable: expmat, ENTER to display the Exp matrix.

**A35: **

1) Complete Col. 1 of the Inference Guide

2) Learn the calculator shortcut for X2GOF and use it for the problems below.

3) pg. 642-648 / **9 b,c** (

TI83+ - no shortcut for you :(

Goodness-of-Fit: enter Obs counts into L1 and Exp counts into L2. Use the lists to calculte the Chi2 component and store ( STO->) in a new list (L3). 2nd,STAT, arrow to MATH, 5:SUM,L3,ENTER. Draw/lable the curve and use X2cdf( , 999, df) to calculate the P-value.

TI84 - use the above proceedure or the shortcut below

**Wed. Thurs 3/13,14 B_Day 34)** Discover a test for an entire
distribution rather than just one proportion.
Go throught the list of class activities below.

**(2) Skittles:** Each group of 4 students will be given a bag of Skittles. **Don't eat them yet! **Discuss group hygiene standards and take necessary precautions. For example use hand sanitizer and place them on a paper towel. Open the Skittles and count how many of each flavor/color. Record your results in the column "Observed Counts" in the table on page 1 of the class notes.

Page 1 Example 1-A: complete in your groups.
