Before submitting a manuscript to the journal, the corresponding author should ensure that all co-authors have seen and approved the final version of the manuscript and have agreed to send the article to JNSA. The authors must declare whether there is any conflict of interest at the point of submission. Papers that have already been published or submitted for publication elsewhere are not accepted. Co-authors must have made significant contributions to the paper in the following aspects: the conception, design, execution, data analysis and interpretation. Emphasis is on originality. The journal views guest authorship, ghost writing, data falsification/fabrication and inaccurate statements as unethical publishing behaviour and are unacceptable. Authors should ensure that they obtain permission for licensed works before using them and such works must be appropriately cited. Whenever authors discover any fundamental errors in the published work, it is their duty to promptly inform the Editor-in-Chief in order to retract and correct the paper.

The Editor-in-Chief of JNSA is responsible for deciding the quality of a manuscript before it is sent for review as well as checking for plagiarism and copyright infringement of any manuscript submitted to the journal. The editor, other editorial advisers, reviewers and editorial staff must treat information about a submitted manuscript as confidential. All papers are reviewed by at least three independent reviewers under a blind review procedure. Editorial communications with the authors may assist them in improving the quality of submitted manuscript(s). Decisions on papers are made subject to the advice of the reviewers. A paper is accepted if two of the reviewers’ comments indicate a positive verdict. However, the Editor may return to author(s) without review, any manuscript deemed to be inappropriate for the Journal. Before publishing an accepted paper, the corresponding author (on behalf of other authors) must complete, sign and submit a copyright agreement form to the Editor.

Reviewers are expected to express their views as clearly as possible with supporting arguments and also identify relevant published works that have not been cited by the author(s), where necessary. Reviewers should call the editor’s attention to any manuscript in which they have conflicts of interest. 

The Nigerian Statistical Association (NSA) will ensure that all individual published articles are archived and freely accessible on the Journal’s website.
