“…Differences with regard to the statistical analyses used can also be found. Some researchers investigate the occurrence of for example particular sub-sequences as varying from learner to learner and apply multi-level analysis (e.g., Taub, Azevedo, Bouchet, & Khosravifar, 2014;Taub, Azevedo, Bradbury, Millar, & Lester, 2017),while others focus on clusters of learners and instead apply chi-square analysis (e.g., Van Laer & Elen, 2016;Van Laer, Jiang, & Elen, 2018) or variance analysis. Still others argue that statistical analysis based on sub-sequences is insufficient to establish a full picture of learners' learning patterns and prefer to use stochastic models based on the entire sequences to operationalize the investigation of learners' behaviour (e.g., Bannert, Sonnenberg, Mengelkamp, & Pieger, 2015;.…”
