“…Two studies do not explicitly report on the data analysis methods applied, although they clearly state the methodological approaches underpinning their studies (Lawson et al, 2016;Scott & Nichols, 2017). Among the works applying statistical methods, we observe the use of the statistical package for social analysis (e.g., Ifenthaler & Schumacher, 2016;West et al, 2016;Adejo & Connolly, 2017;Mahroeian et al, 2017), including descriptive (e.g., Arnold & Sclater, 2017), inferential statistics (e.g., Slade et al, 2019), exploratory and confirmatory factor analysis (e.g., Whitelock-Wainwright et al, 2019), as well as Rasch analysis (e.g., West et al, 2018). In the works using open coding, we distinguish open and axial descriptive coding (West et al, 2016(West et al, , 2018Brooker et al, 2017;Klein et al, 2019;Jones, 2019aJones, , 2019bTsai et al, 2019).…”
