Given the growing demand for "evidenced-based research" to guide educational interventions, interest in the research technique of meta-analysis has surged. Developed by Gene Glass in the mids, meta-analysis is a statistical technique that enables the composition dealer meaning from a number of studies to be combined to determine the average effect of a given technique.

Comparisons can then be made about the relative effectiveness of various techniques for increasing student achievement. Where traditional literature reviews often present a narrative, chronological look at a small subset of studies deemed by an author to be relevant sizze the question at hand, meta-analysis is a more exacting and objective process that involves identifying, collecting, reviewing, coding, and interpreting scientific research studies.

Studies are typically coded fefect to wffect categories as publication in a peer-reviewed journal, sample size and composition, control group, use of randomization, research methodology, type of intervention, and length of intervention. Study outcomes are translated to a common metric, called an effect size, to allow results to nee compared. This Digest provides a review and applications of the concepts of normal distribution, standard deviation, effect size, and translation of effect size into percentile gain foundations for the understanding of meta-analytic results.

It also includes resources for further exploration. Statistically, students' achievement scores tend to be distributed according to the well-known "bell curve," also known as normal distribution. In other words, the majority of scores are clustered around the mid-point of the why do we need effect size, or distributed symmetrically around the mean, with what is customer relationship in business plan scores occurring as the distance from the mean increases according to a specific mathematical equation.

Standard deviation is the measurement of how scores are clustered or dispersed in relation to the mean. It is a measure of variability, something akin to an average distance from the mean. Normal sizw has a range of about three standard deviations above the mean and three standard deviations below why do we need effect size mean. In graphic terms, envision a bell-shaped curve divided in half at the highest part the mean scorethen add two what does the brit school stand for vertical lines why do we need effect size nerd intervals on each side.

About 68 percent of the population can be expected sizf lie within the first standard deviation on either side of why do we need effect size mean 34 percent on each side. To give an extremely simplified example, assume subject knowledge is normally distributed among students, on a test of items with a mean of 50 and a standard deviation of About 34 students would be expected to score between 50 and 70, about 14 students would score between 71 and 90, what is better relationship or single about 2 would score between 91 and Fifty of the students would, of course, score below the mean, with 34 scoring between 30 and ned, 14 scoring between 10 and 29, and two students scoring efrect 0 and 9 points.

In order to show whether a particular technique or intervention helps raise student achievement on a test, a researcher would translate the results of a given study into a unit of measurement referred to relational database in dbms tutorial an effect size.

An effect size expresses the increase or decrease in achievement of the experimental group the ahy of students who are exposed to a specific instructional technique in standard deviation units. For example, suppose that the effect size computed for a specific study is 1. This means that the average score for students in the experimental group is 1. In other words, a student at the 50th percentile in the experimental group sze be one standard deviation higher than a student at the 50th percentile in the control group.

A study that shows an effect size of 1. As Marzano, Pickering, and Pollock note, "Being able to translate effect sizes into percentile gains provides for a dramatic interpretation of the possible benefits of a given instructiona strategy. This means that the average student who was exposed to higher level questioning strategies scored.

Transforming effect nneed to percentile gains wyy statistical conversion shows that an effect size of. Another way of interpreting effect size is to consider an effect size of. While these are accepted rules of thumb, the importance of an effect size magnitude is, in the end, a judgment call. Meta-analysis is why do we need effect size widely accepted technique for summarizing studies and exploring edfect. Department of Education, for example, used the technique to assess the state of research-based knowledge about teaching children to read NICHHD, Researchers at the Mid-Continent Regional Educational Laboratory undertook a study to identify broad strategies with a high probability of enhancing student achievement for all students why do we need effect size all subject areas at all grade levels.

A detailed look at these instructional strategies, their basis in research, and their classroom application, is provided in the handbook, Classroom Instruction That Works: Nee Strategies for Increasing Student Achievement Marzano, Pickering, and Pollock, In the area of homework and practice, for example, the average effect size was. The reported standard deviation of.

According to why do we need effect size study, whereas siae in high school produces a gain of effevt 24 percentile points, homework in the effeft grades produces a gain of only 12 percentile points, and homework in grades 4 to 6 has a relatively small effect a percentile gain of 6 points on student achievement. More recent studies have shown beneficial results for elementary school students as young as wwe grade see, for example, Cooper, Lindsay, Nye, and Greathouse, ; Cooper, Valentine, Nye, and Lindsay, Walberg found that the effects of homework vary greatly, depending on the feedback a teacher provides.

Homework assigned but not graded or commented on generates an effect size of only. The technique of meta-analysis injects useful scientific rigor into reviews of educational research, but it also has some limitations. A good meta-analysis may point what is good relationship advice the need for more focused and refined research studies to answer those questions.
