  1. STAT 104. Section 8 Daniel Moon

  2. Contents • Feedback on HW #7 • Critical Value • Pooled, Unpooled, and Paired t-test • F-test • P-Value (Sample size is very large  Low P) • Plus Four • Two-way Tables • Chi-square

  3. How to take critical value • One-sided • (95%) Critical Value • Z: 1.65 • Two-sided • (95%) Critical Value • Z: 1.96 • F 0.025,33, 43 = ~1.90 • F > F 0.025,33, 43

  4. Feedback Paired Pooled Unpooled F test no significant difference in variance Follows Normal the most conservative Sample number should be same Weight Gain Q. Pooled vs. Paired ? Sensitivity to an unequal sample data point vs. ?

  5. F-test • Are extremely sensitive to nonnormal distributions • F-test can be used for comparing several means • Multiple Regression

  6. Plus Four

  7. Chi-square distribution

  8. Two-way ANOVA Standardized residual

  9. Two-way ANOVA
