Evaluation of Statistical Tools used by Educational Researchers and Evaluators in Data
Analysis of Journal Article Publications
The study investigated the statistical tools used by educational researchers in data analysis of
journal article publications. It determined the prevalent and appropriateness of statistical tools for
researches conducted. The study surveyed journal publications of Educational Research and
Evaluation by Nigerian Association of Educational Researchers and Evaluators (NAERE) now
known and addressed as Association of Educational Researchers and Evaluators of Nigeria
(ASSEREN) and Journals of Curriculum Studies by Curriculum Organization of Nigeria (CON)
from 2007 to 2015 in different volumes and numbers. Fifty- five articles in Journal of
Educational Research and Evaluation and 15 articles in Journal of Curriculum Studies were
sampled. The sample comprised 70 Journal article publications. The publications were evaluated
according to type of statistical tools used for data analysis to assess the most prevalent statistical
tool in data analysis of journal published articles and the appropriateness of such tools to address
the research interest. Frequency counts and percentages were used to analyze the data. The
findings revealed that the statistical tool used by researchers in journal article publications in
NAERE and CON are Descriptive statistics, T-test, Multiple Regression, Analysis of Variance
(ANOVA), Z-test, Correlation, Analysis of Covariance (ANCOVA), Chi-square, Improvement
Index (INI), Factor analysis, Kendalla Tau and Multiple Regression Analysis (MANOVA). The
findings also revealed that the most prevalent statistics used for data analysis in journal
publications of NAERE and CON is the descriptive statistics. It was recommended that
researchers should also go for more in-depth research that could give room for inferential
statistics applications whose results could also inform policy formulation.00
