Mean Output per Institution (MOI)
Mean Output per Institution measures the average research output of universities within each ownership category in South-South Nigeria. It is calculated by dividing the total number of documents produced within a given block by the number of universities in that block. In simple terms, MOI shows how productive the average university is within each ownership group. This makes it useful for comparing the average institutional output of federal, state, and private universities.
Formula
MOI = Number of Documents in the Block / Number of Institutions in the Block
Usefulness
- Shows average institutional output within each ownership category.
- Helps distinguish block size from average university productivity.
- Useful for comparing ownership groups.
Strengths
- Simple average that is easy to interpret.
- Useful for block-level comparison.
- Helps reduce the effect of unequal block sizes.
Limitations
- Can hide differences between universities within the same block.
- Sensitive to extreme values in small blocks.
- Does not account for age or staff size.
Ranking table
| Overall Rank | Block | Number of Institutions | Number of Documents | MOI (Block Documents/Number of Institutions in the block) |
|---|---|---|---|---|
| 1 | Federal Universities | 7 | 27,970 | 3995.71 |
| 2 | State Universities | 12 | 11,730 | 977.50 |
| 3 | Private Universities | 5 | 1,046 | 209.20 |
Note: Values represent the average number of Scopus indexed documents produced per institution within each block. Data were extracted from the Scopus database and were accurate as of 12 pm, 9 February 2026.
