For enrichment (not required):

check out an explanation of the limitations of Chi-square tests.
explaination of degrees of freedom: Degrees of freedom, df, is simply an index of the amount of random variability, mere chance coincidence, that can be present in a particular situation. Its closest literal translation would be something along the line of "degrees of arbitrariness." (see link for more info)

3/20,21 B_Day 37) Practice chi-square calculator shortcuts. Learn the importance of and how to calculate standardized residuals (see TI download options under the assignment).
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.
A37:
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)
TI83/84 standardized residuals program download scroll down to stdres.zip
