Target of replication: *A priori* experimental protocols, materials, and confirmatory analysis plans were peer reviewed, [pre-registered][1], and published by [*eLife*][2]. This component includes all primary and QC data for the third protocol of the replication of [Vermeulen et al., 2010][3]. These experiments include: ### Contents ### [Figures component][4], contains a visualization of the results. These figures are the same as can be found in the Replication Study and include Figure 2 and Figure 2-figure supplement 1 [Statistical Analyses component][5] contains R scripts that were used for the analysis. [Data Component][6], contains data generated from the experimental work related to Protocol 3 of the Registered Report (*in vitro* clonogenicity assay) [Methods Component][7], contains the methods relating to Protocol 3 of the Registered Report (*in vitro* clonogenicity assay) [1]: https://osf.io/rscpj/ [2]: https://elifesciences.org/articles/07301 [3]: https://www.nature.com/articles/ncb2048 [4]: https://osf.io/f9gcs/wiki/home/ [5]: https://osf.io/bqrms/wiki/home/ [6]: https://osf.io/bqrms/wiki/home/ [7]: https://osf.io/qwemb/wiki/home/
