the average score of the experimental group was better than 75% of the control group's scores

In a meta-analysis, the ES for the experimental versus control groups was 0.68, which represents a percentile equivalent of 75. This means that

effect size

In a meta-analysis, the results of various studies on a topic are quantified using a standard measure (ES) that is called

the pretest standard deviation

In calculating ES for a treatment effect between a pretest and a posttest, the text recommends the use of which standard deviation?

the description of the coding of study characteristics and the criteria for excluding studies

The fact that a meta-analysis quantifies findings from many studies is a frequently mentioned advantage. Another strong advantage of the meta-analysis over the normal review paper is

delimitations

The inclusion criteria in a meta-analysis are very much like

the studies represent wide differences in methodologies, designs, and measurements

The most frequent and severe criticism of meta-analysis is that

for empirical and theoretical conclusions

A major difference in the purpose of a meta-analysis and a review of literature for a research paper is that the meta-analysis uses the literature

outliers

It is common when looking at a distribution to encounter extreme or unusual scores that could have a misleading effect on the results. These extreme scores are termed
