Abstract This review study was designed to map out the research trends through an intensive text analysis of 7525 research articles (RAs) of Applied Linguistics during the past thirty years (from 1986 to 2015). The extensive review of the RAs revealed a broad range of themes that belonged to fourteen research domains. Of the total content areas, SLA was found to be the most frequent area (20.82%). Results of analysis for determining the major trends of research methods in Applied Linguistics RAs showed that, empirical studies (83.23%) were by far the most frequent studies. Non-empirical studies were only present in (16.77%) RAs. Among the empirical studies quantitative studies (48%) were more frequent than qualitative (29.02%) and mixedmethods (6.21%) studies. Regarding the statistical techniques, results showed that descriptive statistics (40.04%) were by far the most commonly use technique followed by one-way ANOVA (14.91%), t-test (10.15%), and Pearson correlation (8.76%). Regarding the sophistication level of statistical use, about 78.77% of the techniques were classified as basic, 14.49% as intermediate, and 6.74% as advanced. So, a person with basic knowledge of statistics could understand 69.03% of the papers published during 1986 to 2015.
