  3. Estimation--$100 • Use this inferential procedure when you want to determine whether a treatment effect exists in the population. • answer

  4. Estimation--$200 • Use this inferential procedure when you know there’s a significant difference but want to figure out how much of a difference. • answer

  5. Estimation--$300 • The type of estimate that gives maximum precision, but little confidence. • answer

  6. Estimation--$400 • As the percentage of confidence increases, the width of a confidence interval gets _____. • answer

  7. Estimation--$500 • In estimation, this provides the best estimate of the population mean (or the population mean difference). • answer

  8. ANOVA Shorthand--$100 • The difference between N and n. • answer

  9. ANOVA Shorthand--$200 • SSTotal is divided into these two components. • answer

  10. ANOVA Shorthand--$300 • If F(3, 24) = 5.67, then k = __. • answer

  11. ANOVA Shorthand--$400 • If t(18) = 3.0, then F(1,18) = ___. • answer

  12. ANOVA Shorthand--$500 • If k = 5 and dfTotal = 39, then dfWithinTreatments = ___. • answer

  13. ANOVA Concepts--$100 • When Ho is true, the value of F will be ________. • answer

  14. ANOVA Concepts--$200 • The two component calculations that make up the F-ratio. • answer

  15. ANOVA Concepts--$300 • The two values you need to look up the critical value of F. • answer

  16. ANOVA Concepts--$400 • This variance is an estimate of pure error. • answer

  17. ANOVA Concepts--$500 • The name and formula for the most common measure of effect size used with ANOVA. • answer

  18. Post hoc tests--$100 • k must be at least ___ in order for post hoc tests to be necessary. • answer

  19. Post hoc tests--$200 • These comparisons directly follow from the research hypothesis and are usually few in number, so no special precautions are required. • answer

  20. Post hoc tests--$300 • This is approximately equal to • # of comparisons X alpha per comparison. • answer

  21. Post hoc tests--$400 • This procedure defines the minimum mean difference required for significance and can be used with all possible pairwise comparisons. • answer

  22. Post hoc tests--$500 • Uses k from the overall experiment to produce a very cautious method for reducing type I error. • answer

  23. Surprise--$100 • Add the SSs for all individual treatment conditions to get this. • answer

  24. Surprise--$200 • Of 80% and 95%, the interval estimate yielding the most precision (the narrower interval). • answer

  25. Surprise--$300 • If Fcrit = 4.0 for a particular data set, tcrit = ___ for that same data set. • answer

  26. Surprise--$400 • The alternative hypothesis for an overall ANOVA consisting of k = 4. • answer

  27. Surprise--$500 • This value must be looked up in a table in order to compute Tukey’s HSD. • answer
