Mean and Mean difference are the two key statistical measures used in the statistical analysis. Both are essential for meta-analysis as well. Mean and Mean difference are used for the interpretation of a large set of values into a single number which explains the heterogeneity and variation among the individual values. However, one of a common challenge in meta-analysis is the unavailability of this data (mean and standard deviation).

Q: What is Open Access (OA)?
Effect Size
Open Access is the term used for referencing for free, easy and legally accessible platforms of research articles and publication. OA content includes:
- Journal publications
- Conference articles
- Data sets
- Monographs
- Theses and dissertations
- Source code
Types of Open Access
- Gold Open Access: Papers are easily and freely accessible through publication, often funded by article processing charges.
- Green Open Access: Scholars post a model of their work in institutional sources for open access.
- Hybrid Open Access: Some research papers in subscription journals are available for free and open access, often requiring researchers to pay cost.
Open Educational Resources:
Like Open Access, Open Educational Resources provide free and open accessibility to:
- Online books and textbooks
- Quizzes and test assessments
- Teaching papers for students and educators
These resources increase education but serve a different option from Open Access research.
