Deck 21: Descriptive Statistics

Question 1

The major indicator of a meta-analysis is its effect size.

Answer 1

True

Question 2

A regression line and a celeration line both measure the same type of trend, but the regression line is more precise because it uses more of the available information.

Answer 2

True

Question 3

With the sophisticated measures of effect size presented in this chapter (the delta index, the d-index, the g-index, and the improvement rate difference), we have statistical formulae that provide the basis for asserting causality.

Answer 3

False

Question 4

Recent evidence shows the celeration line is particularly useful as a test of statistical significance.

Question 5

A d-index of .00 shows the intervention had a negative effect.
