In pooling, data sets are first combined and then the groups are compared. In meta-analysis, groups in different data sets are compared first and then the comparisons are combined. In the previous example the data set is partitioned by logical categories e. When there is no obvious way to split the data, Cheung and Jak recommended partitioning the data randomly if the data set is very big.
Moderate and Advanced Analytical Methods The first thing you should do with your data is tabulate your results for the different variables in your data set. This process will give you a comprehensive picture of what your data looks like and assist you in identifying patterns.
The best ways to do this are by constructing frequency and percent distributions A frequency distribution is an organized tabulation of the number of individuals or scores located in each category see the table below. This will help you determine: Variable Frequencies for Student Summer Program Survey Data A percent distribution displays the proportion of participants who are represented within each category see below.
The most common descriptives used are: Mean — the numerical average of scores for a particular variable Minimum and maximum values — the highest and lowest value for a particular variable Median — the numerical middle point or score that cuts the distribution in half for a particular variable Calculate by: Listing the scores in order and counting the number of scores If the number of scores is odd, the median is the number that splits the distribution If the number of scores is even, calculate the mean of the middle two scores Mode — the most common number score or value for a particular variable Depending on the level of measurement, you may not be able to run descriptives for all variables in your dataset.
The mode most commonly occurring value is 3, a report of satisfaction.
Crosstabs allow you to disaggregate the data across multiple categories. By looking at the table below, you can clearly see that the demographic makeup of each program city is different. This allows you to take a deeper look at the units that make up that category. In the table below, we explore this subcategory of participants more in-depth.
From this table, you can see that: All of the students who were dissatisfied with the program were students of color.
All but one of the students of color in the Boston program were dissatisfied with their experience since there were 6 students of color in the Boston program. This result is masked when you report the average satisfaction level of all participants in the program is 2.
In addition to the basic methods described above there are a variety of more complicated analytical procedures that you can perform with your data. Correlation Regression Analysis of variance These types of analyses generally require computer software e.
We provide basic descriptions of each method but encourage you to seek additional information e. For more information on quantitative data analysis, see the following sources: Correlation A correlation is a statistical calculation which describes the nature of the relationship between two variables i.
An important thing to remember when using correlations is that a correlation does not explain causation.In the K education market, where countries the world over publicly finance and manage the great majority of their schools, the institutions and policies established by various levels of government must create incentives for school personnel to use their resources in ways that maximize performance.
Analyze definition is - to study or determine the nature and relationship of the parts of (something) by analysis. How to use analyze in a sentence. mean demonstrating that the voters' intuitive judgments are roughly what they would get if they analyzed the likely effects of candidates' policies, and this is a difficult calculation to.
The existing literature, whether in economics or in education science, has focused on educational outcomes rather than inputs and processes, and indeed on one type of apart from the effect of years of schooling attained.

Analyse the effects of education on the developing countries Development is one of the themes of modern society and there are a variety of elements influencing the development.
Many countries experience declares that education gradually play a more and more vital role in development.
