The aim of this study is to analyze the gender differences on computer-related achievement, anxiety and attitude in Turkey sample. With an aim to combine the results obtained from the independent studies conducted on computer achievement, computer anxiety and computer-related attitude; three different meta-analysis studies were conducted. Various criteria were used in order to determine which studies were going to be included in metaanalysis. Within this context, both Turkish and English studies conducted during 2000-2014 were analyzed; 16 studies on achievement, 17 studies on anxiety and 30 studies on attitude from Turkey sample containing sample size, standard deviation and average values were included in the research. The studies containing the relevant data were analyzed with random effects model. As result of the study, effect size of gender differences for computer achievement, computer anxiety and computer-related attitude were found as 0.012, 0.237 and 0.114 respectively. The values obtained were evaluated according to the classification made by Thalheimer and Cook , it was detected that effect sizes regarding gender differences for computer achievement and computer-related attitude were negligible but effect sizes regarding gender differences for computer anxiety were small in favor of male individuals.
