Estimation--$100

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

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

Estimation--$300

- The type of estimate that gives maximum precision, but little confidence.
- answer

Estimation--$400

- As the percentage of confidence increases, the width of a confidence interval gets _____.
- answer

Estimation--$500

- In estimation, this provides the best estimate of the population mean (or the population mean difference).
- answer

ANOVA Shorthand--$100

- The difference between N and n.
- answer

ANOVA Shorthand--$200

- SSTotal is divided into these two components.
- answer

ANOVA Shorthand--$300

- If F(3, 24) = 5.67, then k = __.
- answer

ANOVA Shorthand--$400

- If t(18) = 3.0, then F(1,18) = ___.
- answer

ANOVA Shorthand--$500

- If k = 5 and dfTotal = 39, then dfWithinTreatments = ___.
- answer

ANOVA Concepts--$100

- When Ho is true, the value of F will be ________.
- answer

ANOVA Concepts--$200

- The two component calculations that make up the F-ratio.
- answer

ANOVA Concepts--$300

- The two values you need to look up the critical value of F.
- answer

ANOVA Concepts--$400

- This variance is an estimate of pure error.
- answer

ANOVA Concepts--$500

- The name and formula for the most common measure of effect size used with ANOVA.
- answer

Post hoc tests--$100

- k must be at least ___ in order for post hoc tests to be necessary.
- answer

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

Post hoc tests--$300

- This is approximately equal to
- # of comparisons X alpha per comparison.
- answer

Post hoc tests--$400

- This procedure defines the minimum mean difference required for significance and can be used with all possible pairwise comparisons.
- answer

Post hoc tests--$500

- Uses k from the overall experiment to produce a very cautious method for reducing type I error.
- answer

Surprise--$100

- Add the SSs for all individual treatment conditions to get this.
- answer

Surprise--$200

- Of 80% and 95%, the interval estimate yielding the most precision (the narrower interval).
- answer

Surprise--$300

- If Fcrit = 4.0 for a particular data set, tcrit = ___ for that same data set.
- answer

Surprise--$400

- The alternative hypothesis for an overall ANOVA consisting of k = 4.
- answer

Surprise--$500

- This value must be looked up in a table in order to compute Tukey’s HSD.
- answer
