This report presents a review of the statistical practices of 30 journals representative of the second language field. A review of 150 articles showed a number of prevalent statistical violations including incomplete reporting of reliability, validity, non-significant results, effect sizes, and assumption checks as well as making inferences from descriptive statistics and failing to correct for multiple comparisons. Scopus citation analysis metrics and whether a journal is SSCI-indexed were…

CiteScore: Advances, Evolution, Applications, and Limitations
Elsevier’s (Scopus) CiteScore, a journal-based metric (JBM), has been assigned to more journals than Clarivate Analytics’ Journal Impact Factor (JIF), including journals indexed by Scopus that do not
CiteScore: Advances, Evolution, Applications, and Limitations
While use of the CiteScore can provide interesting information about how a journal is being cited, the use of this JBM as a “quality” metric is cautioned.
Analysis of Percentiles of Computer Science, Theory and Methods Journals CiteScore Versus Impact Factor
Caution is recommended in journal evaluation as conflicting different results can be obtained using the same metric and the median test contradicts the ANOVA as the medians of impact factor and CiteScore are different at 0.05 level of significance.
Citing Retracted Papers Affects Education and Librarianship, so Distorted Academic Metrics Need a Correction
A prototype concept of the corrected journal impact factor (cJIF) is introduced to correct the most widespread journal-based metric, the Clarivate Analytics journal impact factors (JIF), as a possible solution to correct journal- based metrics that may have become distorted by the citation of retracted papers.

Inspired by the works of scholars who have done great efforts to improve study quality in second language (L2) papers in the recent decade (e.g., Hu & Plonsky, 2019; Larson-Hall, 2012, 2017; Plonsky,
A methodological synthesis and meta-analysis of judgment tasks in second language research
Judgment tasks (JTs, often called acceptability or grammaticality judgment tasks) are found extensively throughout the history of second language (L2) research. Data from such instruments have been


SJR and SNIP: two new journal metrics in Elsevier's Scopus
Two journal metrics recently endorsed by Elsevier's Scopus are introduced: SCImago Journal Rank (SJR) and Source Normalized Impact per Paper (SNIP).
Scopus's Source Normalized Impact per Paper (SNIP) versus a Journal Impact Factor based on Fractional Counting of Citations
Fractional counting of citations can be contextualized at the paper level and aggregated impacts of sets can be tested for their significance, and it can be shown that the weighted impact of Annals of Mathematics is not so much lower than that of Molecular Cell despite a five-f old difference.
