Erwin Segal

Final Exam Study

 

Topics
1.
Sampling distributions (mean, z, t, F, proportion)
    Compare sampling distributions to samples
2. Hypothesis testing; One and two tailed tests; Null Hypotheses; Alternative hypotheses
    decisions; critical values
    Type 1 and type 2 errors: a and b
3. Power- What is power? What influences power? Evaluating power
4.
Point and Interval estimates of parameters
5.
Direct difference t tests: identify, compute and interpret, df

6. Independent sample t tests: identify, compute and interpret, df
7. significance and effect size for t-tests, Anova, and correlation, d, eta squared, r2
8. Simple analysis of variance: (within, between, total), compute and interpret,
     sums of squares, SS, Mean Squares, MS,  

9. post hoc and planned comparisons, Q, Newman-Keuls, Tukey HSD
10. Two-way analysis of variance: compute and interpret
       Main effects and interactions

11. Correlation : properties, compute and interpret, concepts--SP, SSX, SSY, df  
      
Tests for the significance of a correlation coefficient
12. Regression: compute regression line from data and also from , , sx, sy , and r,
        find predicted Y from X; explain regression toward the mean, understand two “best-fit” regression
       lines,  
r2, 1-r2
      Standard error of estimate; percent of variance accounted for, sy.x
, r2,  SSy.x ,  ,
       Variance of regression line, Variance around the regression line

Primarily discussed in my web notes and in Text Chapters 7-17. (I would suggest using web notes as primary source for topic identification)
