HW - 2013 Part II

Inferences for Regression (2)

In class students completed inferences for regression.  We are now finished with the course and will start to review.

The notes are attached and the homework is listed below.

Notes - Linear Regression (2)

HW - pg. 672-676 (37, 38)

Quiz - Chi-squared Tests

In class students took a quiz on Chi-Squared Tests.  Afterwards, students completed a review sheet on linear regression.  If you did not finish the assignment, complete it for homework.

HW - Linear Regression Review

Inference for Regression

In class students went over the practice quiz on chi-squared tests.  Afterwards, students reviewed how to calculate linear regression and interpret statistics related to the regression (ex. r, r-squared).

The notes are attached and the homework is listed below.

Notes - Inference for Regression (1)

HW - Read pgs. 656-667
          Finish Investigative Task #12
          Study for Quiz - Chi-Squared Tests

Review - Chi-Squared Tests

In class students reviewed chi-squared tests for goodness-of-fit, homogeneity, and independence.  Students should now be able to complete a hypothesis test for each, state an appropriate conclusions and check the standardized residuals if necessary.

The homework is attached below.

HW - Practice Quiz - Comparing Counts - due 4/15...quiz Friday 4/17

          Investigative Task #12 - AP Stat Scores - due 4/17

Chi-Squared Test for Independence

In class students learned how to conduct a chi-squared test for independence which is similar to the process used for the chi-squared test for homogeneity.

The notes are attached and there is no homework.  Have a good break!
